Clomitab 50 mg Tabs is prescribed for the treatment of ovulatory failure in women who wish to become pregnant and whose husbands are fertile and potent. Properly timed sexual intercourse is very important to increase the chances of conception. The likelihood of conception diminishes with each succeeding course of treatment. Your doctor will determine the need for continuing therapy after the first course. If you do not ovulate after 3 courses or do not become pregnant after 3 ovulations, your doctor will stop the therapy.
