Why is this medication prescribed?

Firazyr is a medication prescribed for the treatment of acute attacks of hereditary angioedema (HAE) in adults, adolescents, and children aged 2 years and older. Hereditary angioedema is a rare genetic disorder characterized by episodes of severe swelling in various parts of the body, including the hands, feet, face, abdomen, and throat. These attacks can be painful and potentially life-threatening, particularly if they affect the airway.

Firazyr contains the active ingredient icatibant, which is a selective bradykinin B2 receptor antagonist. Bradykinin is a substance in the body that can contribute to the development of swelling in HAE attacks. By blocking the effects of bradykinin, Firazyr helps to reduce the severity and duration of HAE attacks.

How should this medicine be used?

Firazyr (icatibant) is typically used to treat acute attacks of hereditary angioedema (HAE) in adults, adolescents (aged 12 years and older), and children (aged 2 years and older). Here are the general guidelines for using Firazyr:

• Administration: Firazyr is administered as a subcutaneous injection, which means it is injected under the skin. It should be injected into the fatty tissue of the abdomen (stomach area) or thigh.
• Dosage: The recommended dose of Firazyr for adults and adolescents (aged 12 years and older) is 30 mg, administered as a single subcutaneous injection. For children aged 2 to 12 years, the dose is based on body weight, with a maximum dose of 30 mg.
• Timing: Firazyr should be administered as soon as possible after the onset of symptoms of an acute HAE attack. It is most effective when given early in the attack.
• Self-administration: Some patients may be trained to self-administer Firazyr injections. Healthcare professionals can provide instructions on proper injection technique and monitoring for adverse reactions.
• Medical supervision: While Firazyr can be self-administered in certain cases, it’s essential to seek medical attention immediately after using it to manage an acute HAE attack. This ensures proper evaluation and monitoring, as well as potential follow-up treatment if necessary.
• Follow-up: After using Firazyr, patients should follow up with their healthcare provider for further evaluation and management of their HAE condition. It’s essential to discuss the frequency of attacks and any changes in symptoms to adjust treatment as needed.

Always follow the specific instructions provided by your healthcare provider for the proper use of Firazyr, including dosage, administration technique, and any precautions or warnings. Never hesitate to ask questions if you’re unsure about how to use the medication correctly.
