FAM-O 40

# FAMOTIDINE 40 MG ## SHORT DESCRIPTION **Famotidine 40 mg** is an **H2-receptor antagonist (H2 blocker)** that reduces the amount of acid produced in the stomach. It is used to treat conditions associated with excessive stomach acid, including **peptic ulcers, gastroesophageal reflux disease (GERD), and certain hypersecretory conditions**. Famotidine can help relieve symptoms such as **heartburn, acid reflux, and stomach discomfort caused by excess acid**. --- ## KEY BENEFITS * **Reduces Stomach Acid:** Decreases the production of gastric acid. * **Relieves Heartburn:** Helps reduce burning discomfort associated with acid reflux. * **Supports GERD Management:** Helps control acid-related symptoms in people with gastroesophageal reflux disease. * **Helps Treat Peptic Ulcers:** Can promote healing and reduce acid-related irritation of stomach or intestinal ulcers. * **Provides Longer Acid Control:** Famotidine has a relatively long duration of action compared with some older H2 blockers. * **Helps Prevent Acid-Related Symptoms:** May be prescribed to reduce recurrence of certain acid-related conditions. --- ## USES / INDICATIONS Famotidine may be prescribed for: * **Gastroesophageal reflux disease (GERD)** * **Heartburn associated with acid reflux** * **Gastric (stomach) ulcers** * **Duodenal ulcers** * Conditions involving excessive stomach acid production, such as **Zollinger-Ellison syndrome** * Other acid-related gastrointestinal conditions when recommended by a healthcare professional The approved indications and dosing may vary by country and product. --- ## HOW IT WORKS Famotidine selectively blocks **histamine-2 (H2) receptors** on acid-producing cells in the stomach. Normally, stimulation of these receptors increases gastric acid production. By blocking them, famotidine: * Reduces gastric acid secretion * Lowers stomach acidity * Relieves acid-related irritation * Allows acid-damaged tissues to heal Famotidine does **not** neutralize existing stomach acid. Instead, it reduces the amount of new acid produced. --- ## DOSAGE & ADMINISTRATION **Take Famotidine 40 mg exactly as prescribed by your doctor.** The dose and treatment duration depend on the condition being treated and kidney function. * Famotidine may be taken **with or without food**. * Take it at approximately the same time each day when used regularly. * Swallow the tablet with water. * Do not take more than the prescribed dose. * Patients with reduced kidney function may require a lower dose or different dosing interval. ### Missed Dose Take the missed dose when remembered unless it is nearly time for the next scheduled dose. If it is close to the next dose, skip the missed dose. **Do not take two doses at the same time.** --- ## SIDE EFFECTS ### Common Side Effects * Headache * Dizziness * Constipation * Diarrhea * Nausea * Abdominal discomfort ### Less Common Side Effects * Fatigue * Dry mouth * Changes in taste * Mild skin rash ### Serious Side Effects Seek medical attention if you develop: * Severe allergic reaction * Facial, lip, tongue, or throat swelling * Difficulty breathing * Severe or persistent skin rash * Confusion or unusual mental changes, particularly in older adults or people with kidney problems * Yellowing of the skin or eyes --- ## PRECAUTIONS & WARNINGS Before taking Famotidine 40 mg, tell your healthcare professional if you have: * **Kidney disease** * Liver disease * A history of stomach or intestinal ulcers * Difficulty swallowing * Unexplained weight loss * Persistent vomiting * Gastrointestinal bleeding * A history of allergy to famotidine or other H2 blockers ### Kidney Disease Famotidine is primarily eliminated through the kidneys.
