Before Using This Medicine

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For chorionic gonadotropin, the following should be considered:

Allergies - Tell your doctor if you have ever had any unusual or allergic reaction to chorionic gonadotropin. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.

Pregnancy - If you become pregnant as a result of using this medicine with menotropins (e.g., Pergonal) or urofollitropin (e.g., Metrodin), there is an increased chance of a multiple pregnancy (for example, twins, triplets).

Children - Chorionic gonadotropin, when used for treating cryptorchidism (a birth defect where the testes remain inside the body), has caused the sexual organs of some male children to develop too rapidly.

Other medicines - Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your health care professional if you are taking any prescription or nonprescription (over-the-counter [OTC]) medicine.

Other medical problems - The presence of other medical problems may affect the use of chorionic gonadotropin. Make sure you tell your doctor if you have any other medical problems, especially:

• Asthma or
• Epilepsy (seizures) or
• Heart problems or
• Kidney problems or
• Migraine headaches - This medication may worsen these conditions.

• Cancer of the prostate or
• Precocious puberty (a condition that causes early puberty in boys before 9 years of age) - Increases in the amount of testosterone in the bloodstream may make these conditions worse.

• Cyst on ovary or
• Fibroid tumors of the uterus - Chorionic gonadotropin can cause further growth of cysts on the ovary or fibroid tumors of the uterus

• Unusual vaginal bleeding - Irregular vaginal bleeding is a sign that the endometrium is growing too much, of endometrial cancer, or of other hormone imbalances; the increases in estrogen production caused by ovulation can aggravate these problems of the endometrium. If other hormone imbalances are present, they should be treated before beginning ovulation induction
