Firazyr Dosage

Firazyr is a drug that is given as an injection just under the skin (subcutaneously) to treat sudden attacks of swelling caused by hereditary angioedema (HAE). The recommended Firazyr dosage is the same for everyone, regardless of age or weight. However, you can repeat the dose if your symptoms return or do not improve; do not use more than 3 doses in a 24-hour period.

An Introduction to Dosing With Firazyr

There is only one standard dosage of Firazyr® (icatibant). However, you may need to repeat the dose if your symptoms return or do not improve. 
As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.

What Is the Recommended Firazyr Dosage?

The usual recommended dosage of Firazyr for treating acute attacks associated with hereditary angioedema is 30 mg (3 mL). You can give yourself another dose if your symptoms have not improved or have returned, and it has been at least six hours since your previous dose. However, do not use more than 3 doses of this medicine in a 24-hour period.

  • Your healthcare provider will teach you how to self-inject Firazyr. Make sure you understand exactly how to use it before giving yourself injections.
