Overview
Icatibant is a bradykinin B2 receptor antagonist that is FDA approved for the {{{indicationType}}} of acute attacks of hereditary angioedema (HAE) in adults 18 years of age and older. Common adverse reactions include pyrexia, transaminase increase, dizziness, and rash.
Adult Indications and Dosage
FDA-Labeled Indications and Dosage (Adult)
Hereditary Angioedema
- The recommended dose of FIRAZYR is 30 mg administered by subcutaneous (SC) injection in the abdominal area. Additional doses may be administered at intervals of at least 6 hours if response is inadequate or if symptoms recur. No more than 3 doses may be administered in any 24 hour period.
- FIRAZYR should be inspected visually for particulate matter and discoloration prior to administration. The drug solution should be clear and colorless. Do not administer if the product contains particulates or is discolored.
- Attach the provided 25 gauge needle to the syringe hub and screw on securely. Do not use a different needle. Disinfect the injection site and administer FIRAZYR by subcutaneous injection over at least 30 seconds.
- Patients may self-administer FIRAZYR upon recognition of symptoms of an HAE attack after training under the guidance of a healthcare professional [see Patient Counseling Information (17)].

Adverse Reactions
Clinical Trials Experience
- The safety of icatibant was evaluated in three controlled trials that included 223 patients who received FIRAZYR 30 mg (n=113), placebo (n=75), or comparator (n=38). The mean age at study entry was 38 years (range 18 to 83 years), 64% were female, and 95% were white. The data described below represent adverse reactions observed from the two placebo-controlled trials, consisting of 77 patients who received FIRAZYR at a dose of 30 mg SC, and 75 who received placebo.
- The most frequently reported adverse reactions (occurring in greater than 1% of patients and at a higher rate with FIRAZYR versus placebo) are shown in Table 1.
- Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
