It is also used for in vitro fertilization, where eggs are taken out of the woman's body, fertilized by sperm, and put back into her uterus.

This medicine is also used to test how well the hypothalamus and pituitary glands are working.

Before using this medicine, tell your health care provider if you have ever had:

• an allergic reaction to any medicine
• thyroid or adrenal gland problems
• tumors of the ovary, uterus, breast, testicles, or pituitary gland
• unusual vaginal bleeding
• an ovarian cyst or any unusual growth in the ovaries.

Females of childbearing age: Tell your health care provider if you are pregnant or plan to become pregnant. Do not breast-feed while taking this medicine without your health care provider's approval.

Shots of this medicine are timed with your monthly periods. Your health care provider will determine the dosage and the number of shots you will receive based on your response to the first few shots. You will be given these shots over several days or weeks.

The shots are given just under the skin. If your health care provider is giving you the shots, keep all your appointments.

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 shots and how much medicine to use. Use sterile, disposable syringes and needles. Use each syringe and needle only once and dispose of them safely, following your health care provider's instructions.

Carefully read and follow the directions that come in the package of medicine for preparing the shots. Wash your hands before using this medicine. Follow these steps to give yourself the shots:

1. Your health care provider will tell you where you can give yourself the shots (abdomen, thigh, upper arm, or other sites). If you are giving the shot in your abdomen, choose a site) 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° to 90° angle. After you insert the needle completely, release your grasp of the skin.
4. Inject all of the solution by gently and steadily pushing down the plunger.
5. After you have given yourself the shot, withdraw the needle and syringe and press a gauze pad on the spot where the shot was given.
6. 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.

When you repeat the procedure, use a new syringe.

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

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 health care provider.

If you are not having in vitro fertilization, your health care provider will tell you on which days each month you need to have sexual intercourse. It may take several months to become pregnant.
