How does this medication work? What will it do for me?
Misoprostol belongs to the class of medications called synthetic prostaglandins. This medication is used to treat and prevent stomach (gastric) and intestinal (duodenal) ulcers.
It is used to treat and prevent ulcers caused by a class of painkillers called nonsteroidal anti-inflammatory drugs (NSAIDs). It is also used to treat ulcers caused by peptic ulcer disease, which are most often caused by H. pylori (a bacteria that causes ulcers of the stomach and intestine).
Misoprostol is a synthetic prostaglandin that acts just like the natural prostaglandin found in your body. It works by decreasing acid and increasing mucus and blood flow to the stomach, which protects the walls of the stomach and intestine.
This medication may be available under multiple brand names and/or in several different forms.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Diarrhea: Rare instances of severe diarrhea leading to dehydration have been reported with use of this medication. People with an underlying condition such as irritable bowel disease or those for whom dehydration would be dangerous should be monitored closely by their doctor.
Epilepsy: Epileptic seizures have been reported with medications like misoprostol when administered by routes other than oral (by mouth). Therefore, misoprostol should be used by people with epilepsy only when their epilepsy is adequately controlled and the expected benefits outweigh the potential risks.
Pregnancy: Women who may become pregnant should use adequate birth control (e.g., birth control pills, condoms, or intrauterine devices) while taking misoprostol. Since misoprostol increases the risk of miscarriage, a woman who may be pregnant should not start taking misoprostol until she is sure that she is not pregnant. If you suspect you are pregnant, stop the medication and contact your doctor.
Breast-feeding: Breast-feeding mothers should not take misoprostol, as it may cause significant diarrhea for breast-feeding infants.
Children: The safety and effectiveness of this medication have not been established for children and adolescents under 18 years of age.
