Clomid (clomiphene) is a medicine prescribed for women unable to have a child because of certain hormonal problems. It stimulates the release of specific hormones that cause ovulation to occur making it possible for the patient to become pregnant. Clomid has been classified as FDA pregnancy category X – it is very dangerous for the health of an unborn baby. You need to take all the necessary precautions to avoid getting pregnant while you are taking this medicine, and your health care provider or your pharmacist may give you advice on the birth control methods you could use. As most drugs Clomid can cause a number of side effects. Although these side effects may be quite unpleasant your health care provider may recommend taking Clomid anyway – the period of treatment is just 5 days, every menstrual cycle. The most commonly reported side effects include diarrhea, nausea, vomiting, abnormal uterine bleeding, swellings, flushing, breast tenderness and diarrhea. Make sure your health care provider knows about any of these side effects, as lowering your dosage may help. Since every doctor has a slightly different recommended routine of taking this medicine make sure you call you health care provider if you happened to miss a dose.
