Misoprostol is a medication used to prevent stomach ulcers in people who are taking nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin and ibuprofen. It is also used to induce labor in pregnant women and for the treatment of missed miscarriage. Misoprostol works by reducing acid secretion in the stomach and increasing the production of protective mucus.
Misoprostol is available in tablet form for oral administration, typically in doses of 100 or 200 micrograms. The dosage and duration of treatment may vary depending on the condition being treated and the individual's response to the medication. Common side effects include diarrhea, abdominal pain, nausea, and headache. Misoprostol is not recommended for use during pregnancy as it can cause birth defects or miscarriage. It is also contraindicated in people with a history of allergy to prostaglandins or any of the ingredients in the medication.
