Cimetidine

Drug Details

Cimetidine, known by the brand name Tagamet HB, is a medication that reduces stomach acid production. It is classified as an H2 blocker, which works by blocking histamine receptors in the stomach, thereby decreasing acid output. This drug is commonly used to treat and prevent various conditions related to excess stomach acid such as stomach and intestinal ulcers, gastroesophageal reflux disease (GERD), and disorders like Zollinger-Ellison syndrome. It also alleviates symptoms like heartburn, stomach pain, and difficulty swallowing caused by acid indigestion. For over-the-counter (OTC) use, Cimetidine is available to relieve and prevent heartburn for individuals aged 12 and older. However, prescription-strength doses are required to manage more severe conditions and are suitable for those 16 and older. Depending on the specific condition being treated, Cimetidine can be taken orally one to four times a day. While generally well-tolerated, some users may experience mild side effects such as headache, dizziness, or diarrhea. It is crucial to follow the package instructions carefully and consult a healthcare professional for guidance, especially if using this medication for self-treatment. Note that Cimetidine should not be used in children under 12 without a doctor's advice.
