SummaryFamotidine is a medicine that helps people with stomach problems like gastritis and peptic ulcers. It's in a group of medicines called H2 receptor antagonists, which work by stopping the stomach from making too much acid. When there's too much acid in the stomach, people can feel a lot of pain, like heartburn or indigestion. Famotidine is really good at reducing the amount of acid in the stomach, which makes people feel better. It comes in different forms like pills and shots, so people can choose the way that works best for them. Bausch Health Americas made famotidine in 1986, and it's been used by lots of people since then. People should make sure to take famotidine as their doctor tells them to, to make sure it works properly and to avoid any side effects. |
