Firazyr Dosage/Direction for Use

Firazyr is intended for use under the guidance of a healthcare professional.
Posology: Adults: The recommended dose for adults is a single subcutaneous injection of Firazyr 30 mg.
In the majority of cases a single injection of Firazyr is sufficient to treat an attack. In case of insufficient relief or recurrence of symptoms, a second injection of Firazyr can be administered after 6 hours. If the second injection produces insufficient relief or a recurrence of symptoms is observed, a third injection of Firazyr can be administered after a further 6 hours. No more than 3 injections of Firazyr should be administered in a 24 hour period.
In the clinical trials, not more than 8 injections of Firazyr per month have been administered.
Paediatric population: The recommended dose of Firazyr based on body weight in children and adolescents (aged 2 to 17 years) is provided in Table 3 as follows. (See Table 3.)

In the clinical trial, not more than 1 injection of Firazyr per HAE attack has been administered.
No dosage regimen for children aged less than 2 years or weighing less than 12 kg can be recommended as the safety and efficacy in this paediatric group has not been established.
Elderly: Limited information is available on patients older than 65 years of age.
Elderly people have been shown to have increased systemic exposure to icatibant. The relevance of this to the safety of Firazyr is unknown (see Pharmacology: Pharmacokinetics under Actions).
Hepatic impairment: No dose adjustment is required in patients with hepatic impairment.
Renal impairment: No dose adjustment is required in patients with renal impairment.
Method of administration: Firazyr is intended for subcutaneous administration preferably in the abdominal area.
Firazyr solution for injection should be injected slowly due to the volume to be administered.
Each Firazyr syringe is intended for single use only.
Refer to the patient information leaflet for instructions for use.
Caregiver/self-administration: The decision on initiating caregiver or self-administration of Firazyr should only be taken by a physician experienced in the diagnosis and treatment of hereditary angioedema (see Precautions).
Adults: Firazyr may be self-administered or administered by a caregiver only after training in subcutaneous injection technique by a healthcare professional.
Children and adolescents aged 2-17 years: Firazyr may be administered by a caregiver only after training in subcutaneous injection technique by a healthcare professional.
