Combination drug: Arthrotec
Misoprostol is a type of drug called a prostaglandin E1 analog that protects the mucosal lining of the stomach and intestines. It is either used alone or in combination with non-steroidal anti-inflammatory drugs (NSAIDs) to prevent injury to stomach and intestinal tissue caused by these agents.

Interactions with Dietary Supplements
Magnesium
A common side effect of misoprostol is diarrhea, which is aggravated by taking magnesium.1 Consequently, individuals who experience diarrhea while taking misoprostol should avoid magnesium supplementation.
Interactions with Foods and Other Compounds
Food
Taking misoprostol with food may lower the maximum concentration of the drug in the blood and delay (though not decrease) absorption up to ten hours.2 3 However, since ingestion of food with misoprostol may reduce the incidence of diarrhea, it is usually recommended that the drug be taken with a meal.4
