Cimetidine is a medication that helps relieve and prevent heartburn caused by acid indigestion and sour stomach. It works by reducing the amount of acid your stomach produces, which can help ease discomfort. For adults and children aged 12 and older, you can take 1 tablet with a glass of water either to relieve symptoms as needed or to prevent them up to 30 minutes before eating or drinking things that trigger heartburn, but do not take more than 2 tablets in a 24-hour period. It's important not to use this medication if you have trouble swallowing, vomiting blood, or black stools, as these could indicate a serious condition. Additionally, if you are taking certain prescription drugs, it's best to consult your doctor or pharmacist, as cimetidine may interact with them.
