Icatibant and Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Icatibant falls into category C. In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans, though. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.

Your doctor and you will decide if the benefits outweigh the risk of using icatibant.

Step-by-Step Instructions for your icatibant injection

Step 1. Preparing your dose of icatibant

  • Wash your hands with soap and water.
  • You will need the following supplies:
    • Your icatibant carton that includes 1 single-use icatibant prefilled syringe and 1 needle.
    • An alcohol wipe
    • The medicine inside your icatibant prefilled syringe should be clear and colorless. Do not use your icatibant prefilled syringe if the solution contains particles, is cloudy, or an unusual color.

Step 2. Remove the prefilled syringe and needle from the carton.

Step 3. Remove the seal from the needle cap (the needle should remain inside the protective needle cap until ready to use).

Step 4. Hold the syringe firmly. Carefully attach the needle to the prefilled syringe containing the colorless icatibant solution. 

Step 5. Firmly screw the needle on the prefilled syringe. Be careful not to remove the needle from the needle cap.

Step 6. Choose the injection site. The injection site should be a fold of skin on your stomach, about 2 to 4 inches (5 to 10 cm) below your belly button on either side. 

The area you choose for injection should be at least 2 inches (5 cm) away from any scars. Do not choose an area that is bruised, swollen, or painful.

Step 7. Clean your icatibant injection site with an alcohol wipe and allow it to dry.

Injecting your icatibant

Step 8. Remove the needle from the needle cap by holding the needle cap and carefully pulling the syringe. Do not pull up on the plunger. 

Step 9. Hold the icatibant prefilled syringe in 1 hand, between your fingers and thumb.

Step 10. Use your other hand to gently pinch the fold of skin you cleaned with the alcohol wipe between your thumb and fingers for your injection. 

Step 11. Hold the syringe between a 45 to 90 degree angle to your skin with the needle facing the fold of skin you are holding.

Step 12. Hold the fold of skin. Bring the syringe to the skin and quickly insert the needle into the skin fold.

Step 13. Push the plunger, at the top of the syringe, over at least 30 seconds until no icatibant is in the syringe.

Step 14. Release the skin fold and gently pull the needle out.

Disposal of your used icatibant prefilled syringe

Step 15. Place the used icatibant syringe with the needle attached, in a sharps container (such as a red biohazard container), a hard, plastic container, (such as a detergent bottle), or a metal container (such as an empty coffee can). Seal the container and throw it away the right way. There may be state and local laws about the right way to throw away used syringes and needles. Ask your healthcare provider or pharmacist how to throw away used syringes and needles.
