If you are a woman of childbearing age, you may take misoprostol to prevent ulcers only if you have had a negative pregnancy test in the past 2 weeks and if you use a reliable method of birth control while taking misoprostol. You must begin taking misoprostol on the second or third day of your menstrual period. If you become pregnant while taking misoprostol, stop taking it and call your doctor immediately.

Do not take more or less of it or take it more often than prescribed by your doctor.
Misoprostol must be taken regularly to be effective. Women should not take their first dose until the second or third day of their menstrual period (to be sure that they are not pregnant). Do not stop taking misoprostol without talking to your doctor.

What side effects can this medication cause?

If you experience any of the following symptoms, call your doctor immediately:

If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration's (FDA) MedWatch Adverse Event Reporting program online (http://www.fda.gov/Safety/MedWatch) or by phone (1-800-332-1088).
What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). Throw away any medication that is outdated or no longer needed. Talk to your pharmacist about the proper disposal of your medication.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
