Misoprostol is a medication used for a variety of purposes. It's commonly known for its role in preventing stomach ulcers in patients taking NSAIDs (nonsteroidal anti-inflammatory drugs), as it helps protect the stomach lining. Additionally, misoprostol is used in obstetrics and gynecology for inducing labor and, in combination with other medications, for medical abortions. It works by mimicking the effects of prostaglandins, which help contract the uterus and protect the stomach lining. As with any medication, it's important to use misoprostol under the guidance of a healthcare professional to ensure it's safe and appropriate for your specific needs. If you have questions about its uses or effects, consulting with a doctor or pharmacist would be advisable.
