Omeprazole: Uses, Side Effects, and Drug Interactions
Brand names: Omeprazole
# Omeprazole Overview Omeprazole is a medicine that reduces the amount of acid your stomach makes. Doctors prescribe it to treat heartburn, acid reflux, and ulcers. When you have too much stomach acid, it can cause a burning feeling in your chest or throat. Omeprazole helps by blocking the cells in your stomach that produce acid, giving your digestive system time to heal. Many people use this medicine to feel better and prevent painful symptoms. Before taking omeprazole, there are some important safety things to know. You should talk to your doctor if you're pregnant, breastfeeding, or taking other medicines, since omeprazole might not be safe for you or could interact with other drugs. Don't use this medicine if you're allergic to omeprazole or any ingredients in it. Make sure to follow the dosage instructions your doctor gives you and don't take more than recommended. If you experience any unusual side effects or your symptoms don't improve, stop taking it and contact your doctor right away. Always keep omeprazole out of reach of children.
