How do I use it?

Check the label on the medicine for directions about your specific dose. Follow your healthcare provider's directions exactly.

These shots are given just under the skin (subcutaneous) once a week. Sometimes you can give yourself these shots or have someone at home give them to you. Be sure you know how and when to have them and how much medicine to use. Use sterile, disposable syringes and needles. Use them only once and dispose of them safely, following your healthcare provider's instructions.

Carefully read and follow the directions that come in the package of medicine for the shots.

Wash your hands before using this medicine. Follow these steps to give yourself the shots:

1. Choose a site on your abdomen (thigh, upper arm, or other sites) around the belly button but not in the belly button. Each day, choose a different spot for the shot to lessen irritation.
2. Use an alcohol swab to clean the skin where you will give yourself the shot.
3. Gently pinch up the skin and insert the needle into the skin at a 45-degree angle. After you insert the needle completely, release your grasp of the skin.
4. After you have given yourself the shot, withdraw the needle and syringe and press the alcohol swab at the spot where the shot was given.
5. Discard the syringe, needle, and drug vial. Use the syringes and needles ONLY ONCE. Throw them away after use. Put used needles in rigid puncture-resistant containers with lids or caps, such as heavy plastic bleach bottles with screw caps. DO NOT throw needles directly into garbage cans or dumpsters.

If you are not sure of how to give yourself the shots, ask your healthcare provider or pharmacist for help.

What if I miss a dose?

If you miss a dose, use it as soon as you remember unless it is almost time for the next scheduled dose. In that case, skip the missed dose and use the next one as directed. Do not use double doses. If you are not sure of what to do if you miss a dose, or if you miss more than one dose, contact your healthcare provider.
