Cimetidine belongs to the class of medications known as H2 receptor antagonists. It’s often prescribed for managing conditions such as gastroesophageal reflux disease (GERD), peptic ulcer disease, and Zollinger-Ellison syndrome. While cimetidine is effective in treating these issues, it may also cause a range of side effects, from mild to severe.
In this blog post, we’ll explore both common and serious side effects associated with cimetidine.
