Cimetidine HCl
Cimetidine HCl (Cimetidine Hydrochloride) is a medication used to treat conditions caused by excess stomach acid, including gastroesophageal reflux disease (GERD), ulcers, and Zollinger-Ellison syndrome. As an H2 receptor antagonist, it works by blocking histamine in the stomach, reducing acid production. This helps alleviate heartburn, heal ulcers, and prevent future ulcers. Cimetidine HCl is available in both prescription and over-the-counter forms, depending on the strength and purpose of use.

Comprehensive Drug Guide
How Does Cimetidine HCl Work?
Cimetidine HCl works by inhibiting the action of histamine on H2 receptors found in the stomach lining. Histamine stimulates acid production, so by blocking these receptors, Cimetidine HCl effectively reduces the amount of acid produced. This action helps in treating acid-related conditions such as ulcers and GERD.
Common Dosages
- Tablets: 200 mg, 400 mg, 800 mg
- Oral Solution: 300 mg/5 mL
- Injectable Solution: Typically used in hospital settings with varying dosages based on clinical needs.

Interactions with Cimetidine HCl
Common Drug Interactions
- Warfarin: Cimetidine HCl may increase warfarin levels, requiring close monitoring of blood clotting parameters.
- Phenytoin and Theophylline: These drugs may have increased blood levels when taken with Cimetidine HCl, which could lead to toxicity.
- Alcohol: Cimetidine HCl can increase the effects of alcohol by slowing its breakdown in the body. Alcohol consumption should be limited while taking Cimetidine HCl.
Alternatives to Cimetidine HCl
- Ranitidine: Another H2 receptor antagonist that reduces stomach acid.
- Famotidine: A widely used H2 blocker that is considered more selective and has fewer drug interactions.
- Proton Pump Inhibitors (PPIs): Such as omeprazole or lansoprazole, often used for long-term or severe GERD and ulcer management.
- Antacids: Used for fast, short-term relief of heartburn and indigestion.
