Contents
Micronised purified flavonoid fraction.
Description
500-mg: Each film-coated tablet contains micronised purified flavonoid fraction 500 mg, corresponding to Diosmin 450 mg and Flavonoids expressed as hesperidin: 10 percent equivalent to 50 mg.
1,000-mg: Micronized purified flavonoid fraction 1000 mg corresponding to: Diosmin: 90 percent 900 mg, Flavonoids expressed as hesperidin: 10 percent 100 mg, Mean moisture 40 mg for one film-coated tablet.
The score line is only to facilitate breaking for ease of swallowing and not to divide into equal doses.
Excipients/Inactive Ingredients: Sodium starch glycolate, microcrystalline cellulose, gelatine, magnesium stearate, talc.

Action
Pharmacotherapeutic group: VASOPROTECTIVES/CAPILLARY STABILIZING AGENTS/BIOFLAVONOIDS. C05CA53: Cardiovascular system.
Pharmacology: Pharmacodynamics: In pharmacology: DAFLON exerts a dual action on the venous return system: at vein and venule level, it increases parietal tone and exerts an anti-stasis action, at the microcirculatory level, it reinforces capillary resistance and normalises capillary permeability.
In clinical pharmacology: Controlled, double-blind studies using methods that allow demonstrating and quantifying the activity on venous haemodynamics have confirmed the pharmacological properties of this medicinal product in humans.
Dose/effect relationship: 500-mg: Statistically significant dose-effect relationships have been demonstrated for the following venous plethysmography parameters: Capacitance, distensibility and emptying time. The best dose-effect ratio is obtained with 2 tablets.
1,000-mg: Statistically-significant dose-effect relationships have been demonstrated for the following venous plethysmography parameters: capacitance, distensibility and emptying time. The best dose/effect ratio is obtained with 1 tablet.
Venotonic activity: It increases venous tone; venous occlusion plethysmography with a mercury stain gauge revealed a reduction in venous emptying time.
Microcirculatory activity: Controlled, double-blind studies have demonstrated a statistically-significant difference between this medicinal product and placebo. In patients with signs of capillary fragility, it increases capillary resistance as measured by angiosterrometry.
Efficacy and clinical safety: In clinical practice: Controlled double-blind clinical studies versus placebo demonstrated the therapeutic activity of the medicinal product in phlebology, in the treatment of chronic venous insufficiency (functional and organic) of the lower limbs.
Pharmacokinetics: In humans, following oral administration of the medicinal product with carbon 14-labelled diosmin: Excretion is essentially faecal and urinary excretion is on average of 14% of the administered quantity.
The elimination half-life is 11 hours.
The product is highly metabolised, this metabolism is revealed by the presence of different phenol acids in the urine.
Toxicology: Preclinical safety data: Non-clinical data reveal no special hazard for humans based on conventional studies of repeated dose toxicity, genotoxicity and toxicity to reproduction.
Indications/Uses
Treatment of symptoms related to venolymphatic insufficiency (heavy legs, pain, early morning restless legs).
Treatment of functional symptoms related to acute hemorrhoidal attack.
Dosage/Direction for Use
500-mg: Posology: Usual Dose: 2 tablets daily in 2 divided doses, mid-day and evening at meal times.
Acute Hemorrhoidal Attack: 6 tablets daily for the first 4 days, then 4 tablets daily for 3 days.
Paediatric population: The safety and efficacy of DAFLON 500mg in children and adolescents under 18 years of age have not been established.
1,000-mg: Venolymphatic insufficiency: 1 tablet daily, in the morning at breakfast.
Acute hemorrhoidal attack: 3 tablets per day for the first 4 days, then 2 tablets per day for the next 3 days.
Paediatric population: The safety and efficacy of Daflon 1000 mg in children and adolescents under 18 years of age have not been established.
Method of administration: Oral route.
Overdosage
Symptoms: There is limited experience with DAFLON overdose. The most frequently reported adverse events in overdose cases were gastrointestinal events (such as diarrhoea, nausea, abdominal pain) and skin events (such as pruritus, rash).
Management: Management of overdose should consist in treatment of clinical symptoms.
Contraindications
Hypersensitivity to the active substance or to any of the excipients (see Excipients/Inactive Ingredients under Description).
Special Precautions
Hemorrhoidal attack: The administration of this product does not preclude treatment for other anal conditions. The treatment must be short-term. If symptoms do not subside promptly, a proctological examination should be performed and the treatment should be reviewed.
Effects on the ability to drive and use machines: No specific studies on the effects of flavonoid fraction on the ability to drive and use machines have been performed. However, on the basis of the overall safety profile of flavonoid fraction, DAFLON have nor negligible influence on the ability to drive and use machines.
Use In Pregnancy & Lactation
Pregnancy: There are no or limited amount of data from the use of micronised purified flavonoid fraction in pregnant women.
Animal studies do not indicate reproductive toxicity (see Pharmacology: Toxicology: Preclinical safety data under Actions).
As a precautionary measure, it is preferable to avoid the use of DAFLON during pregnancy.
Breast-feeding:
It is unknown whether the active substance/metabolites are excreted in human milk.
A risk to the newborns/infants cannot be excluded.
A decision must be made whether to discontinue breast-feeding or to discontinue/abstain from DAFLON therapy taking into account the benefit of breast-feeding for the child and the benefit of therapy for the woman.
Fertility:
Reproductive toxicity studies showed no effect on fertility in male and female rats (see Pharmacology: Toxicology: Preclinical safety data under Actions).
