Clomid (clomiphene) is a prescription medication used for women diagnosed with infertility. This drug works by stimulating the production of hormones necessary for an egg to leave the ovaries and later be fertilized by sperm. Clomid has been reported to cause blurred vision in some patients. If you have to drive or operate machinery make sure you know in advance the effects Clomid has on you to avoid putting the lives of other people at risk. If you have any endocrine problems, uterine fibroids, ovarian cysts or enlarged ovaries, endometriosis, underdiagnosed vaginal bleeding, liver disease, or any other chronic illnesses, as well as if you are pregnant, make sure you tell your health care provider about it before the treatment can be started. If you experience such side effects as vomiting, diarrhea, headache, nausea, flushing, swellings, abdominal pain, abdominal swelling or tenderness caused by ovarian enlargement, abnormal uterine bleeding, and breast tenderness report them to the health care provider that prescribed Clomid. In some cases you will be recommended to carry on with the treatment, while in other cases your dose will have to be adjusted to minimize the symptoms.
