Drugs Home > C1 Esterase Inhibitor
- C1 esterase inhibitor comes as a powder that is dissolved in sterile water for injection to form a liquid. It is given as a slow injection into a vein (an intravenous, or IV, injection).
- The injections may be given by your healthcare provider, or (after proper training) self-injected. If you will be self-administering this medication, make sure you completely understand how to prepare your dose and inject it.
- You should wash your hands before preparing your dose, and work on a clean surface to prevent contaminating the medicine with germs.
- If you self-administer C1 esterase inhibitor to treat a laryngeal (voice box) attack, you should seek immediate medical attention after treating yourself. Laryngeal attacks can be life-threatening.
- If you use the medication to treat an abdominal (stomach) attack, let your healthcare provider know afterwards so other possible causes of your symptoms can be excluded.
- For the medication to work properly, it must be used as prescribed.
