About FIRAZYR

Firazyr is a medication aligned to the HCPCS J Code: J1744 for billing, pricing, and reimbursement purposes in the United States. It is an Immunology drug administered via the subcutaneous route and manufactured by multiple companies.

According to CMS Drug Use Information: Icatibant is used to treat sudden attacks of a certain immune system condition passed down through families called hereditary angioedema (HAE). Although this medication is not a cure for HAE, icatibant may lessen the symptoms of an attack such as rapid swelling and pain of the hands, arms, feet, legs, face, tongue, and upper airway. When attacks involve the stomach/intestines, symptoms may include abdominal pain/cramps, diarrhea, constipation, or vomiting. Attacks may happen at any time. However, stress, injury, or illness may trigger attacks in some people. Icatibant works by blocking the action of a natural substance in the body called bradykinin. Bradykinin is thought to cause the symptoms of an HAE attack.
