Special Precautions
Patients and their carers must be instructed that PecFent contains an active substance in an amount that can be fatal to a child.
In order to minimise the risks of opioid-related adverse reactions and to identify the effective dose, it is imperative that patients be monitored closely by health professionals during the titration process.
It is important that the long acting opioid treatment used to treat the patient's persistent pain has been stabilised before PecFent therapy begins.
Respiratory depression: There is a risk of clinically significant respiratory depression associated with the use of fentanyl. Patients with pain who receive chronic opioid therapy develop tolerance to respiratory depression and hence the risk of respiratory depression in these patients is reduced. The use of concomitant central nervous system depressants may increase the risk of respiratory depression.
Chronic pulmonary disease: In patients with chronic obstructive pulmonary diseases, fentanyl may cause more serious adverse reactions. In these patients, opioids may decrease respiratory drive and increase airway resistance.
Increased intracranial pressure: PecFent should only be administered with extreme caution in patients who may be particularly susceptible to the intracranial effects of CO2 retention, such as those with evidence of increased intracranial presssure or impaired consciousness. Opioids may obscure the clinical course of patients with a head injury and should be used only if clinically warranted.
Cardiac disease: Fentanyl may produce bradycardia. PecFent should, therefore, be used with caution in patients with previous or pre-existing bradyarrhythmias.
Impaired hepatic or renal function: In addition, PecFent should be administered with caution to patients with hepatic or renal impairment. The influence of hepatic and renal impairment on the pharmacokinetics of the medicinal product has not been evaluated; however, when administered intravenously the clearance of fentanyl has been shown to be altered in hepatic and renal impairment due to alterations in metabolic clearance and plasma proteins. Therefore, special care should be taken during the titration process in patients with moderate or severe hepatic or renal impairment.
Careful consideration should be given to patients with hypovolaemia and hypotension.
Abuse potential and tolerance: Tolerance and physical and/or psychological dependence may develop upon repeated administration of opioids such as fentanyl. However, iatrogenic addiction following therapeutic use of opioids is rare.
Athletes should be informed that treatment with fentanyl could lead to positive doping tests.
Serotonin Syndrome: Caution is advised when PecFent is coadministered with medicinal products that affect the serotoninergic neurotransmitter systems.
The development of a potentially life-threatening serotonin syndrome may occur with the concomitant use of serotonergic medicinal products such as Selective Serotonin Re-uptake Inhibitors (SSRIs) and Serotonin Norepinephrine Re-uptake Inhibitors (SNRIs), and with medicinal products which impair metabolism of serotonin (including Monoamine Oxidase Inhibitors [MAOIs]). This may occur within the recommended dose.
Serotonin syndrome may include mental-status changes (e.g., agitation, hallucinations, coma), autonomic instability (e.g., tachycardia, labile blood pressure, hyperthermia), neuromuscular abnormalities (e.g., hyperreflexia, incoordination, rigidity), and/or gastrointestinal symptoms (e.g., nausea, vomiting, diarrhoea).
If serotonin syndrome is suspected, treatment with PecFent should be discontinued.
Route of administration: PecFent is only intended for nasal use, and must not be administered by any other route. Due to physico-chemical properties of excipients included in the formulation, intravenous or intra-arterial injection must be avoided in particular.
Nasal conditions: If the patient experiences recurrent episodes of epistaxis or nasal discomfort while taking PecFent, an alternative method of administration for treatment of breakthrough pain should be considered.
PecFent excipients: PecFent contains propyl parahydroxybenzoate (E216), Propyl parahydroxybenzoate may cause allergic reactions (possibly delayed) and, exceptionally, bronchospasm (if the medicinal product is not correctly administered).
Effects on ability to drive and use machines: Opioid analgesics may impair the mental and/or physical ability required for driving or operating machinery.
Patients should be advised not to drive or operate machinery if they experience somnolence, dizziness, or visual disturbance or other adverse reactions which can impair their ability to drive or operate machinery.
