Full Prescribing Info
Contents
Insulin glargine.
Description
Each ml contains 300 units insulin glargine* (equivalent to 10.91 mg).
Each pen contains 1.5 ml of solution for injection, equivalent to 450 units.
*Insulin glargine is produced by recombinant DNA technology in Escherichia coli.
Excipients/Inactive Ingredients: Zinc chloride, Metacresol, Glycerol, Hydrochloric acid (for pH adjustment), Sodium hydroxide (for pH adjustment), Water for injections.
Action
Pharmacotherapeutic group: Drugs used in diabetes, insulins and analogues for injection, long-acting. ATC Code: A10AE04.
Pharmacology: Pharmacodynamics: Mechanism of action: The primary activity of insulin, including insulin glargine, is regulation of glucose metabolism. Insulin and its analogues lower blood glucose levels by stimulating peripheral glucose uptake, especially by skeletal muscle and fat, and by inhibiting hepatic glucose production. Insulin inhibits lipolysis in the adipocyte, inhibits proteolysis and enhances protein synthesis.
Pharmacodynamic effects: Insulin glargine is a human insulin analogue designed to have a low solubility at neutral pH. At pH 4, insulin glargine is completely soluble. After injection into the subcutaneous tissue, the acidic solution is neutralised leading to formation of a precipitate from which small amounts of insulin glargine are continuously released. As observed in euglycemic clamp studies in patients with type 1 diabetes, the glucose lowering effect of Toujeo was more stable and prolonged in comparison with insulin glargine 100 units/ml after subcutaneous injection. Figure 1 shows results from a crossover study in 18 patients with type 1 diabetes conducted for a maximum of 36 hours after injection. The effect of Toujeo was beyond 24 hours (up to 36 hours) at clinically relevant doses. The more sustained release of insulin glargine from the Toujeo precipitate compared to insulin glargine 100 units/ml is attributable to the reduction of the injection volume by two thirds that results in a smaller precipitate surface area. (See figure.)

*GIR: Glucose infusion rate: determined as amount of glucose infused to maintain constant plasma glucose levels (hourly mean values). The end of the observation period was 36 hours.
Insulin glargine is metabolised into 2 active metabolites M1 and M2 (see Pharmacokinetics as follows).
Insulin receptor binding: In vitro studies indicate that the affinity of insulin glargine and its metabolites M1 and M2 for the human insulin receptor is similar to the one of human insulin.
IGF-1 receptor binding: The affinity of insulin glargine for the human IGF-1 receptor is approximately 5 to 8-fold greater than that of human insulin (but approximately 70 to 80-fold lower than the one of IGF-1), whereas M1 and M2 bind the IGF-1 receptor with slightly lower affinity compared to human insulin.
The total therapeutic insulin concentration (insulin glargine and its metabolites) found in type 1 diabetic patients was markedly lower than what would be required for a halfmaximal occupation of the IGF-1 receptor and the subsequent activation of themitogenic-proliferative pathway initiated by the IGF-1 receptor. Physiological concentrations of endogenous IGF-1 may activate the mitogenic-proliferative pathway; however, the therapeutic concentrations found in insulin therapy, including in Toujeo therapy, are considerably lower than the pharmacological concentrations required to activate the IGF-1 pathway.
In a clinical pharmacology study, intravenous insulin glargine and human insulin have been shown to be equipotent when given at the same doses. As with all insulins, the time course of action of insulin glargine may be affected by physical activity and other variables.
Clinical efficacy and safety
The overall efficacy and safety of Toujeo (insulin glargine 300 units/ml) once-daily on glycaemic control was compared to that of once-daily insulin glargine 100 units/ml in open-label, randomised, active-control, parallel studies of up to 26 weeks of duration, including 546 patients with type 1 diabetes mellitus and 2,474 patients with type 2 diabetes mellitus (Table 1 and 2).
Results from all clinical trials with Toujeo indicated that reductions in HbA1c from baseline to end of trial were non-inferior to insulin glargine 100 units/ml. Plasma glucose reductions at the end of the trial with Toujeo were similar to insulin glargine 100 units/ml with a more gradual reduction during the titration period with Toujeo. Glycaemic control was similar when Toujeo was administered once daily in the morning or in the evening.
Improvement in HbA1C was not affected by, gender, ethnicity, age, diabetes duration (<10 years and ≥10 years), HbA1c value at baseline (<8% or ≥8%) or baseline body mass index (BMI).
At the end of these treat-to-target trials, depending on the patient population and concomitant therapy, a 10-18% higher dose was observed in the Toujeo group than in the comparator group (Table 1 and 2).
Results from clinical trials demonstrated that the incidence of confirmed hypoglycaemia (at any time of the day and nocturnal) was lower in patients treated with Toujeo compared to insulin glargine 100 units/ml-treated patients, in patients with type 2 diabetes treated in combination with either non-insulin anti-hyperglycaemic medicinal product or mealtime insulin.
The superiority of Toujeo over insulin glargine 100 units/ml in lowering the risk of confirmed nocturnal hypoglycemia was shown in patients with type 2 diabetes treated with basal insulin in combination with either non-insulin anti-hyperglycaemic medicinal product (18% risk reduction) or mealtime insulin (21% risk reduction) during the period from week 9 to end of study period. Overall, these effects on hypoglycaemia risk were consistently observed whatever the age, gender, BMI and duration of diabetes (<10 years and ≥10 years) in Toujeo-treated patients compared to insulin glargine 100 units/ml-treated patients.
In patients with type 1 diabetes, the incidence of hypoglycaemia was similar in patients treated with Toujeo compared to insulin glargine 100 units/ml-treated patients (Table 1). (See Tables 1-3.)

Flexibility in dosing time: The safety and efficacy of Toujeo administered with a fixed or flexible dosing time were also evaluated in 2 randomized, open-label clinical studies for 3 months. Type 2 diabetic patients (n=194) received Toujeo once daily in the evening, either at the same time of the day (fixed time of administration) or within 3 hours before or after the usual time of administration (flexible dosing time). Administration with a flexible dosing time had no effect on glycaemic control and the incidence of hypoglycaemia.
Antibodies: Results from studies comparing Toujeo and insulin glargine 100 units/ml did not indicate any difference in term of development of anti-insulin antibodies, on efficacy, safety or dose of basal insulin between Toujeo and insulin glargine 100 units/ml.
Body weight: Mean change in body weight of less than 1 kg at the end of the 6-month period was observed in Toujeo-treated patients (see Table 1 and 2).
Results from a study on progression of diabetic retinopathy: Effects of insulin glargine 100 units/ml (once daily) on diabetic retinopathy were evaluated in an open-label 5 year NPH-controlled study (NPH given bid) in 1024 type 2 diabetic patients in which progression of retinopathy by 3 or more steps on the Early Treatment Diabetic Retinopathy Study (ETDRS) scale was investigated by fundus photography. No significant difference was seen in the progression of diabetic retinopathy when insulin glargine 100 units/ml was compared to NPH insulin.
Long term efficacy and safety outcome study: The ORIGIN (Outcome Reduction with Initial Glargine INtervention) study was a multicenter, randomized, 2x2 factorial design study conducted in 12,537 participants at high cardiovascular (CV) risk with impaired fasting glucose (IFG) or impaired glucose tolerance (IGT) (12% of participants) or type 2 diabetes mellitus (treated with ≤1 antidiabetic oral agent) (88% of participants). Participants were randomized (1:1) to receive insulin glargine 100 units/ml (n=6264), titrated to reach FPG ≤95 mg/dl (5.3 mM), or standard care (n=6273).
The first co-primary efficacy outcome was the time to the first occurrence of CV death, nonfatal myocardial infarction (MI), or nonfatal stroke, and the second co-primary efficacy outcome was the time to the first occurrence of any of the first co-primary events, or revascularisation procedure (coronary, carotid, or peripheral), or hospitalisation for heart failure.
Secondary endpoints included all-cause mortality and a composite microvascular outcome.
Insulin glargine 100 units/ml did not alter the relative risk for CV disease and CV mortality when compared to standard of care. There were no differences between insulin glargine and standard care for the two co-primary outcomes; for any component endpoint comprising these outcomes; for all-cause mortality; or for the composite microvascular outcome.
Mean dose of insulin glargine 100 units/ml by study end was 0.42 U/kg. At baseline, participants had a median HbA1c value of 6.4% and median on-treatment HbA1c values ranged from 5.9 to 6.4% in the insulin glargine 100 units/ml group, and 6.2% to 6.6% in the standard care group throughout the duration of follow-up.
The rates of severe hypoglycaemia (affected participants per 100 participant years of exposure) were 1.05 for insulin glargine 100 units/ml and 0.30 for standard care group and the rates of confirmed non-severe hypoglycaemia were 7.71 for insulin glargine 100 units/ml and 2.44 for standard care group. Over the course of this 6-year study, 42% of the insulin glargine 100 units/ml group did not experience any hypoglycaemia.
At the last on-treatment visit, there was a mean increase in body weight from baseline of 1.4 kg in the insulin glargine 100 units/ml group and a mean decrease of 0.8 kg in the standard care group.
Pharmacokinetics: Absorption and distribution: In healthy subjects and diabetic patients, insulin serum concentrations indicated a slower and more prolonged absorption resulting in a flatter time-concentration profile after subcutaneous injection of Toujeo in comparison to insulin glargine 100 units/ml. Pharmacokinetic profiles were consistent with the pharmacodynamic activity of Toujeo.
Steady state level within the therapeutic range is reached after 3-4 days of daily Toujeo administration. After subcutaneous injection of Toujeo, the intra-subject variability, defined as the coefficient of variation for the insulin exposure during 24 hours was low at steady state (17.4%).
Biotransformation: After subcutaneous injection of insulin glargine, insulin glargine is rapidly metabolized at the carboxyl terminus of the Beta chain with formation of two active metabolites M1 (21A-Gly-insulin) and M2 (21A-Gly-des-30B-Thr-insulin). In plasma, the principal circulating compound is the metabolite M1. The exposure to M1 increases with the administered dose of insulin glargine. The pharmacokinetic and pharmacodynamic findings indicate that the effect of the subcutaneous injection with insulin glargine is principally based on exposure to M1. Insulin glargine and the metabolite M2 were not detectable in the vast majority of subjects and, when they were detectable their concentration was independent of the administered dose and formulation of insulin glargine.
Elimination: When given intravenously the elimination half-life of insulin glargine and human insulin were comparable.
The half-life after subcutaneous administration of Toujeo is determined by the rate of absorption from the subcutaneous tissue.
The half-life of Toujeo after subcutaneous injection is 18-19 hours independent of dose.
Toxicology: Preclinical safety data: Non-clinical data reveal no special hazard for humans based on conventional studies of safety pharmacology, repeated dose toxicity, genotoxicity, carcinogenic potential, toxicity to reproduction.
Indications/Uses
Treatment of diabetes mellitus in adults.
Dosage/Direction for Use
Posology: Toujeo is a basal insulin for once-daily administration at any time of the day, preferably at the same time every day.
The dose regimen (dose and timing) should be adjusted according to individual response.
In type 1 diabetes mellitus, Toujeo must be combined with short-/rapid-acting insulin to cover mealtime insulin requirements.
In patients with type 2 diabetes mellitus, Toujeo can also be given together with other anti-hyperglycaemic medicinal products.
The potency of this medicinal product is stated in units. These units are exclusive to Toujeo and are not the same as IU or the units used to express the potency of other insulin analogues (see Pharmacology: Pharmacodynamics under Actions).
Flexibility in dosing time: When needed, patients can administer Toujeo up to 3 hours before or after their usual time of administration (see Pharmacology: Pharmacodynamics under Actions)
Patients who forget a dose, should be advised to check their blood sugar and then resume their usual once-daily dosing schedule.
Patients should be informed not to inject a double dose to make up for a forgotten dose.
Initiation: Patients with type 1 diabetes mellitus: Toujeo is to be used once-daily with meal-time insulin and requires individual dose adjustments.
Patients with type 2 diabetes mellitus: The recommended daily starting dose is 0.2 units/kg followed by individual dose adjustments.
Switch between insulin glargine 100 units/ml and Toujeo: Insulin glargine 100 units/ml and Toujeo are not bioequivalent and are not directly interchangeable.
When switching from insulin glargine 100 units/ml to Toujeo, this can be done on a unit-to-unit basis, but a higher Toujeo dose (approximately 10-18%) may be needed to achieve target ranges for plasma glucose levels.
When switching from Toujeo to insulin glargine 100 units/ml, the dose should be reduced (approximately by 20%) to reduce the risk of hypoglycaemia.
Close metabolic monitoring is recommended during the switch and in the initial weeks thereafter.
Switch from other basal insulins to Toujeo: When switching from a treatment regimen with an intermediate or long-acting insulin to a regimen with Toujeo, a change of the dose of the basal insulin may be required and the concomitant anti-hyperglycaemic treatment may need to be adjusted (dose and timing of additional regular insulins or fast-acting insulin analogues or the dose of non-insulin anti-hyperglycaemic medicinal products).
Switching from once-daily basal insulins to once-daily Toujeo can be done unit-to-unit based on the previous basal insulin dose.
Switching from twice-daily basal insulins to once-daily Toujeo, the recommended initial Toujeo dose is 80% of the total daily dose of basal insulin that is being discontinued.
Patients with high insulin doses because of antibodies to human insulin may experience an improved insulin response with Toujeo.
Close metabolic monitoring is recommended during the switch and in the initial weeks thereafter.
With improved metabolic control and resulting increase in insulin sensitivity a further adjustment in dose regimen may become necessary. Dose adjustment may also be required, for example, if the patient's weight or life-style changes, if there is a change in the timing of insulin dose or if other circumstances arise that increase susceptibility to hypo-or hyperglycaemia (see Precautions).
Switch from Toujeo to other basal insulins: Medical supervision with close metabolic monitoring is recommended during the switch and in the initial weeks thereafter.
Please refer to the prescribing information of the medicinal product to which the patient is switching.
Special populations: Toujeo can be used in elderly people, renal and hepatic impaired patients.
Elderly population (≥65 years old):
In the elderly, progressive deterioration of renal function may lead to a steady decrease in insulin requirements (see Pharmacology: Pharmacodynamics under Actions and Adverse Reactions).
Renal impairment: In patients with renal impairment, insulin requirements may be diminished due to reduced insulin metabolism (see Adverse Reactions).
Hepatic impairment: In patients with hepatic impairment, insulin requirements may be diminished due to reduced capacity for gluconeogenesis and reduced insulin metabolism.
Paediatric population: The safety and efficacy of Toujeo in children and adolescents below 18 years of age have not been established. No data are available.
Method of Administration: Toujeo is for subcutaneous use only. Toujeo is administered subcutaneously by injection in the abdominal wall, the deltoid or the thigh. Injection sites must be rotated within a given injection area from one injection to the next (see Adverse Reactions).
Toujeo must not be administered intravenously. The prolonged duration of action of Toujeo is dependent on its injection into subcutaneous tissue. Intravenous administration of the usual subcutaneous dose could result in severe hypoglycaemia. Toujeo must not be used in insulin infusion pumps.
With Toujeo SoloStar pre-filled pen, a dose of 1-80 units per injection, in steps of 1 unit, can be injected. The dose window shows the number of Toujeo units to be injected. The Toujeo SoloStar pre-filled pen has been specifically designed for Toujeo, therefore no dose re-calculation is required.
Toujeo must not be drawn from the cartridge of the SoloStar pre-filled pen into a syringe or severe overdose can result (see Overdosage and Caution for Usage).
A new sterile needle must be attached before each injection. Re-use of needles increases the risk of blocked needles which may cause underdosing or overdosing (see Caution for Usage).
To prevent possible transmission of disease, insulin pens should never be used for more than one person, even when the needle is changed (see Caution for Usage).
Before using Toujeo SoloStar pre-filled pen, the instructions for use included in the package leaflet must be read carefully (see Caution for Usage).
Overdosage
Symptoms: Insulin overdose may lead to severe and sometimes long-term and life-threatening hypoglycaemia.
Management: Mild episodes of hypoglycaemia can usually be treated with oral carbohydrates. Adjustments in dose of the medicinal product, meal patterns, or physical activity may be needed.
More severe episodes with coma, seizure, or neurologic impairment may be treated with intramuscular/ subcutaneous glucagon or concentrated intravenous glucose. Sustained carbohydrate intake and observation may be necessary because hypoglycaemia may recur after apparent clinical recovery.
Contraindications
Hypersensitivity to the active substance or to any of the excipients.
Special Precautions
Toujeo is not the insulin of choice for the treatment of diabetic ketoacidosis. Instead, regular insulin administered intravenously is recommended in such cases.
In case of insufficient glucose control or a tendency to hyper- or hypoglycaemic episodes, the patient's adherence to the prescribed treatment regimen, injection sites and proper injection technique and all other relevant factors must be reviewed before dose adjustment is considered.
Hypoglycaemia: The time of occurrence of hypoglycaemia depends on the action profile of the insulins used and may, therefore, change when the treatment regimen is changed.
Particular caution should be exercised, and intensified blood glucose monitoring is advisable in patients in whom hypoglycaemic episodes might be of particular clinical relevance, such as in patients with significant stenoses of the coronary arteries or of the blood vessels supplying the brain (risk of cardiac or cerebral complications of hypoglycaemia) as well as in patients with proliferative retinopathy, particularly if not treated with photocoagulation (risk of transient amaurosis following hypoglycaemia). Patients should be aware of circumstances where warning symptoms of hypoglycaemia are diminished. The warning symptoms of hypoglycaemia may be changed, be less pronounced or be absent in certain risk groups. These include patients: in whom glycaemic control is markedly improved, in whom hypoglycaemia develops gradually, who are elderly, after transfer from animal insulin to human insulin, in whom an autonomic neuropathy is present, with a long history of diabetes, suffering from a psychiatric illness, receiving concurrent treatment with certain other medicinal products (see Interactions).
Such situations may result in severe hypoglycaemia (and possibly loss of consciousness) prior to the patient's awareness of hypoglycaemia.
The prolonged effect of insulin glargine may delay recovery from hypoglycaemia.
If normal or decreased values for glycated haemoglobin are noted, the possibility of recurrent, unrecognised (especially nocturnal) episodes of hypoglycaemia must be considered.
Adherence of the patient to the dose and dietary regimen, correct insulin administration and awareness of hypoglycaemia symptoms are essential to reduce the risk of hypoglycaemia. Factors increasing the susceptibility to hypoglycaemia require particularly close monitoring and may necessitate dose adjustment. These factors include: change in the injection area, improved insulin sensitivity (e.g., by removal of stress factors), unaccustomed, increased or prolonged physical activity, intercurrent illness (e.g. vomiting, diarrhoea), inadequate food intake, missed meals, alcohol consumption, certain uncompensated endocrine disorders, (e.g. in hypothyroidism and in anterior pituitary or adrenocortical insufficiency), concomitant treatment with certain other medicinal products (see Interactions).
Switch between insulin glargine 100 units/ml and Toujeo: Since insulin glargine 100 units/ml and Toujeo are not bioequivalent and are not interchangeable, switching may result in the need for a change in dose and should only be done under strict medical supervision (see Dosage & Administration).
Close metabolic monitoring is recommended during the switch and in the initial weeks thereafter.
Switch between other insulins and Toujeo: Switching a patient between another type or brand of insulin and Toujeo should be done under strict medical supervision. Changes in strength, brand (manufacturer), type (regular, NPH, lente, long- acting, etc.), origin (animal, human, human insulin analogue) and/or method of manufacture may result in the need for a change in dose (see Dosage & Administration).
The onset of action of Toujeo develops over 6 hours following an injection. In type 1 diabetes patients treated with IV insulin, consider the longer onset of action of Toujeo before stopping IV insulin. The full glucose lowering effect may not be apparent for at least 3 days.
Intercurrent illness: requires intensified metabolic monitoring. In many cases urine tests for ketones are indicated, and often it is necessary to adjust the insulin dose. The insulin requirement is often increased. Patients with type 1 diabetes must continue to consume at least a small amount of carbohydrates on a regular basis, even if they are able to eat only little or no food, or are vomiting etc. and they must never omit insulin entirely.
Insulin antibodies: Insulin administration may cause insulin antibodies to form. In rare cases, the presence of such insulin antibodies may necessitate adjustment of the insulin dose in order to correct a tendency to hyper-or hypoglycaemia.
Combination of Toujeo with pioglitazone: Cases of cardiac failure have been reported when pioglitazone was used in combination with insulin, especially in patients with risk factors for development of cardiac heart failure. This should be kept in mind if treatment with the combination of pioglitazone and Toujeo is considered. If the combination is used, patients should be observed for signs and symptoms of heart failure, weight gain and oedema. Pioglitazone should be discontinued if any deterioration in cardiac symptoms occurs.
Medication errors prevention: Insulin label must always be checked before each injection to avoid medication errors between Toujeo and other insulins (see Caution for Usage).
Patients must visually verify the number of selected units on the dose counter of the pen. Patients who are blind or have poor vision should be instructed to get help/assistance from another person who has good vision and is trained in using the insulin device. (See Adiministration under Dosage & Administration.)
Excipients: This medicinal product contains less than 1 mmol (23 mg) sodium per dose, i.e. it is essentially 'sodium-free'.
Effects on ability to drive and use machines: The patient's ability to concentrate and react may be impaired as a result of hypoglycaemia or hyperglycaemia or, for example, as a result of visual impairment. This may constitute a risk in situations where these abilities are of special importance (e.g. driving a car or using machines).
Patients should be advised to take precautions to avoid hypoglycaemia whilst driving. This is particularly important in those who have reduced or absent awareness of the warning symptoms of hypoglycaemia or have frequent episodes of hypoglycaemia. It should be considered whether it is advisable to drive or use machines in these circumstances.
Use In Pregnancy & Lactation
Pregnancy: There is no clinical experience with use of Toujeo in pregnant women.
For insulin glargine no clinical data on exposed pregnancies from controlled clinical studies are available. A large amount of data on pregnant women (more than 1,000 pregnancy outcomes with a medicinal product containing insulin glargine 100 units/ ml) indicate no specific adverse effects on pregnancy and no specific malformative nor feto/neonatal toxicity of insulin glargine.
Animal data do not indicate reproductive toxicity.
The use of Toujeo may be considered during pregnancy, if clinically needed.
It is essential for patients with pre-existing or gestational diabetes to maintain good metabolic control throughout pregnancy to prevent adverse outcomes associated with hyperglycemia. Insulin requirements may decrease during the first trimester and generally increase during the second and third trimesters. Immediately after delivery, insulin requirements decline rapidly (increased risk of hypoglycaemia). Careful monitoring of glucose control is essential.
Breast-feeding: It is unknown whether insulin glargine is excreted in human milk. No metabolic effects of ingested insulin glargine on the breast-fed newborn/infant are anticipated since insulin glargine as a peptide is digested into amino acids in the human gastrointestinal tract.
Breast-feeding women may require adjustments in insulin dose and diet
Fertility: Animal studies do not indicate direct harmful effects with respect to fertility.
Adverse Reactions
Summary of the safety profile: The following adverse reactions were observed during clinical studies conducted with Toujeo (see Pharmacology: Pharmacodynamics under Actions) and during clinical experience with insulin glargine 100 units/ml.
Hypoglycaemia, in general the most frequent adverse reaction of insulin therapy, may occur if the insulin dose is too high in relation to the insulin requirement.
Tabulated list of adverse reactions: The following related adverse reactions from clinical investigations are listed as follows by system organ class and in order of decreasing incidence (very common: ≥1/10; common: ≥1/100 to <1/10; uncommon: ≥1/1,000 to <1/100; rare: ≥1/10,000 to <1/1,000; very rare: <1/10,000; not known: cannot be estimated from the available data).
Within each frequency grouping, adverse reactions are presented in order of decreasing seriousness. (See Table 4.)

Description of selected adverse reactions: Metabolism and nutrition disorders: Severe hypoglycaemic attacks, especially if recurrent, may lead to neurological damage. Prolonged or severe hypoglycaemic episodes may be life-threatening. In many patients, the signs and symptoms of neuroglycopenia are preceded by signs of adrenergic counter-regulation. Generally, the greater and more rapid the decline in blood glucose, the more marked is the phenomenon of counter-regulation and its symptoms.
Immune system disorders:
Immediate-type allergic reactions to insulin are rare. Such reactions to insulin (including insulin glargine) or the excipients may, for example, be associated with generalised skin reactions, angio-oedema, bronchospasm, hypotension and shock, and may be life-threatening. In Toujeo clinical studies in adult patients, the incidence of allergic reactions was similar in Toujeo-treated patients (5.3%) and insulin glargine 100 units/ml-treated patients (4.5%).
Eyes disorders: A marked change in glycaemic control may cause temporary visual impairment, due to temporary alteration in the turgidity and refractive index of the lens. Long-term improved glycaemic control decreases the risk of progression of diabetic retinopathy. However, intensification of insulin therapy with abrupt improvement in glycaemic control may be associated with temporary worsening of diabetic retinopathy. In patients with proliferative retinopathy, particularly if not treated with photocoagulation, severe hypoglycaemic episodes may result in transient amaurosis.
Skin and subcutaneous tissue disorders:
Lipodystrophy may occur at the injection site and delay local insulin absorption. Continuous rotation of the injection site within the given injection area may help to reduce or prevent these reactions.
General disorders and administration site conditions: Injection site reactions include redness, pain, itching, hives, swelling, or inflammation. Most minor reactions to insulins at the injection site usually resolve in a few days to a few weeks. In Toujeo clinical studies in adult patients, the incidence of injection site reactions was similar in Toujeo-treated patients (2.5%) and insulin glargine 100 units/ml-treated patients (2.8%).
Rarely, insulin may cause oedema particularly if previously poor metabolic control is improved by intensified insulin therapy.
Paediatric population:
No clinical studies with Toujeo have been conducted in the paediatric population. Therefore, the safety profile of Toujeo has not been established.
Other special populations: Based on the results from clinical studies, the safety profile of Toujeo in elderly patients and in patients with renal impairment was similar to that of the overall population (see Pharmacology: Pharmacodynamics under Actions).
Reporting of suspected adverse reactions: Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the national reporting system.
Drug Interactions
A number of substances affect glucose metabolism and may require dose adjustment of insulin glargine.
Substances that may enhance the blood-glucose-lowering effect and increase susceptibility to hypoglycaemia include antihyperglycaemic medicinal products, angiotensin converting enzyme (ACE) inhibitors, disopyramide, fibrates, fluoxetine, monoamine oxidase (MAO) inhibitors, pentoxifylline, propoxyphene, salicylates and sulfonamide antibiotics.
Substances that may reduce the blood-glucose-lowering effect include corticosteroids, danazol, diazoxide, diuretics, glucagon, isoniazid, oestrogens and progestogens, phenothiazine derivatives, somatropin, sympathomimetic medicinal products (e.g. epinephrine [adrenaline], salbutamol, terbutaline), thyroid hormones, atypical antipsychotic medicinal products (e.g. clozapine and olanzapine) and protease inhibitors. Beta-blockers, clonidine, lithium salts or alcohol may either potentiate or weaken the blood-glucose-lowering effect of insulin. Pentamidine may cause hypoglycaemia, which may sometimes be followed by hyperglycaemia.
In addition, under the influence of sympatholytic medicinal products such as beta-blockers, clonidine, guanethidine and reserpine, the signs of adrenergic counter-regulation may be reduced or absent.
Caution For Usage
Special precautions for disposal and other handling: Before first use, the pen must be stored at room temperature at least 1 hour before use.
Before using Toujeo SoloStar pre-filled pen, the Instructions for Use included in the package leaflet must be read carefully. Touje SoloStar pre-filled pen has to be used as recommended in these Instructions for Use (see Dosage & Administration).
The cartridge should be inspected before use. It must only be used if the solution is clear, colourless, with no solid particles visible, and if it is of water-like consistency. Since Toujeo is a solution, it does not require resuspension before use.
Insulin label must always be checked before each injection to avoid medication errors between Toujeo and other insulins. The strength "300" is highlighted in honey gold on the label (see Precautions).
A syringe must never be used to withdraw Toujeo from the cartridge of the SoloStar pre-filled pen or severe overdose can result (see Dosage & Administrtaion).
Needles must be discarded immediately after use. A new sterile needle must be attached before each injection. Re-use of needles increases the risk of blocked needles which may cause underdosing or overdosing. Using a new sterile needle for each injection also minimizes the risk of contamination and infection. In the event of blocked needle, the patients must follow the instructions described in Step 3 of the Instructions for Use accompanying the package leaflet (see Dosage & Administration).
Used needles should be thrown away in a puncture resistant container or disposed of in accordance with local requirements.
Empty pens must never be reused and must be properly discarded.
To prevent possible transmission of disease, insulin pen should never be used by for more than one person, even when the needle is changed (see Dosage & Administration).
Incompatibilities: Toujeo must not be mixed or diluted with any other insulin or other medicinal products. Mixing or diluting Toujeo changes its time/action profile and mixing causes precipitation.
Storage
Before first use: Store in a refrigerator (2°C-8°C).
Do not freeze or place next to the freezer compartment or a freezer pack. Keep the pre-filled pen in the outer carton in order to protect from light.
After first use or if carried as a spare: For storage conditions after first opening of this medicinal product, see previously mentioned.
Shelf-Life: 30 months.
Shelf life after first use of the pen: The medicinal product may be stored for a maximum of 6 weeks below 30°C and away from direct heat or direct light. Pens in use must not be stored in the refrigerator. The pen cap must be put back on the pen after each injection in order to protect from light.
