6 ADVERSE REACTIONS The most commonly reported adverse reactions were injection site reactions, which occurred in almost all patients (97%) in clinical trials.
Other common adverse reactions occurring in greater than 1% of patients included pyrexia, transaminase increase, dizziness, and rash.

6.1 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
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.

5 WARNINGS AND PRECAUTIONS Laryngeal attacks: Following treatment of laryngeal attacks with FIRAZYR, advise patients to seek immediate medical attention.
( 5.1 ) 5.1 Laryngeal Attacks Given the potential for airway obstruction during acute laryngeal HAE attacks, patients should be advised to seek medical attention in an appropriate healthcare facility immediately in addition to treatment with FIRAZYR.
Like all medications, Firazyr can cause side effects. However, not everyone who takes this medication will experience them. Many side effects are dose-dependent and may improve as your body adjusts to the medication. Others may require dose adjustment or medical attention.
