Clomid (clomiphene) is an ovulatory stimulant specially intended for women diagnosed with infertility whose ovaries do not produce eggs and some medical stimulation is necessary. This drug can be taken for the treatment of infertility only after you have been examined by your health care provider and obtained a negative pregnancy test. Clomid can affect the health on an unborn child very seriously and therefore must never be taken by pregnant or breastfeeding women. Make sure you tell your doctor before taking Clomid for the first time if you have any of the following medical condition that may be important in determining the safety of using Clomid: endometriosis, uterine fibroids, endometrial carcinoma, ovarian cysts, undiagnosed vaginal bleeding, any chronic medical illness, pregnancy, thyroid problem, endocrine disorder, or liver disease. Report any serious side effects right away - especially double vision, stomach swelling, blurred vision, stomach or lower stomach pain, weight gain, shortness of breath, visual spots or flashes. Less serious side effects are more likely and include breast discomfort, flushing, upset stomach, headache, vomiting, and abnormal vaginal bleeding.
