Famotidine 20 mg tablets are a prescription-strength medication used to treat conditions caused by excessive stomach acid, such as ulcers and severe acid reflux.
Key Uses
Famotidine works as a histamine H2-receptor antagonist, decreasing the amount of acid the stomach produces to help heal and prevent ulcers and reduce related symptoms.
It is primarily used to treat:
- Stomach and duodenal ulcers (sores on the lining of the stomach or small intestine).
- Gastroesophageal reflux disease (GERD), stomach acid flows back into the esophagus, causing heartburn and injury.
- Erosive esophagitis (inflammation/damage to the lining of the esophagus) due to acid reflux.
- Zollinger-Ellison syndrome and other conditions where the stomach produces too much acid.
Important Precautions & Warnings
- Do not stop suddenly: Do not stop taking the medication without consulting your doctor, as this may delay the healing process or worsen your symptoms.
- Kidney issues: The dose may need to be adjusted for patients with kidney problems, as the medicine is removed by the kidneys.
- Lifestyle adjustments: Avoiding alcohol, reducing stress, and avoiding certain spicy or acidic foods may help the medication work better.
