Summary
Famotidine is used to treat heartburn, which is a burning sensation in the chest, gastroesophageal reflux disease (GERD), which is a condition where stomach acid frequently flows back into the tube connecting your mouth and stomach, and ulcers, which are sores on the lining of the stomach or small intestine.
Famotidine works by blocking histamine, which is a chemical that stimulates acid production in the stomach. This action reduces stomach acid, helping to relieve symptoms like heartburn and promote healing of the stomach lining.
The usual starting dose for adults is 20 mg to 40 mg once or twice daily, depending on the condition. It can be taken with or without food. Always follow your doctor's specific dosing instructions and do not exceed the recommended dose without medical advice.
Common side effects of Famotidine include headache, which is pain in the head, dizziness, which is a sensation of spinning or losing balance, and constipation, which is difficulty in emptying the bowels.
Do not take Famotidine if you're allergic to it. It should be used with caution in people with kidney problems, as it may require dose adjustments. Always inform your doctor about any medical conditions or allergies before starting Famotidine.
