Motidin (Famotidine)

Famotidine, the active ingredient in Motidin, is a H2 receptor antagonist presented as an oral tablet for oral use. It reduces gastric acid production and is employed in the management of ulcer‑related and acid‑reflux conditions in adults. It works by blocking histamine H2 receptors on gastric parietal cells, leading to decreased secretion of stomach acid and promotion of ulcer healing.

GNH USA supplies Motidin as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Famotidine is used to treat several acid‑related gastrointestinal conditions. - Peptic ulcer disease: promotes ulcer healing and reduces recurrence by lowering gastric acid secretion. - Gastroesophageal reflux disease (GERD): alleviates heartburn and regurgitation symptoms through acid suppression. - Erosive esophagitis: aids mucosal healing by decreasing acid exposure in the esophagus. - Zollinger‑Ellison syndrome: controls excessive gastric acid production associated with gastrin‑secreting tumors.

Famotidine may cause a range of adverse reactions, which are categorized by frequency and severity.

Common Side Effects: - Headache: mild to moderate pain in the head region. - Dizziness: sensation of light‑headedness or unsteadiness. - Diarrhea: loose, watery stools occurring intermittently. - Nausea: feeling of queasiness or urge to vomit. - Constipation: infrequent or hard stools. - Rash: mild skin redness or itching.

Serious or Rare Side Effects: - Anaphylaxis: severe, potentially life‑threatening allergic reaction with breathing difficulty. - Cardiac arrhythmias: irregular heart rhythms that may require medical attention. - Neutropenia: significant reduction in neutrophil count increasing infection risk. - Hepatic enzyme elevation: abnormal liver function tests indicating possible liver injury. - Thrombocytopenia: low platelet count leading to bleeding tendencies.

When prescribing or dispensing Famotidine, several precautions should be considered to ensure safe use. - Renal function assessment: adjust dose in patients with impaired kidney function. - Elderly patients: monitor for increased sensitivity and possible accumulation. - Concomitant use with antacids: separate administration times to avoid reduced absorption. - Discontinuation: avoid abrupt cessation in patients with severe ulcer disease without medical guidance. - Pregnancy and lactation: evaluate risk‑benefit ratio before use. - Store at ambient temperature: keep below 25 °C in original packaging, protect from moisture.

Famotidine can affect or be affected by other medicines; interactions are classified by clinical significance.

Major Interactions (Avoid): - Antacids containing aluminum or magnesium: markedly decrease famotidine absorption; separate dosing by at least 2 hours. - Ketoconazole or itraconazole: reduced antifungal efficacy due to increased gastric pH. - Atazanavir: diminished antiviral absorption leading to subtherapeutic levels.

Moderate Interactions (Monitor Closely): - Warfarin: potential alteration of anticoagulant effect; monitor INR. - Theophylline: possible increase in plasma concentration; observe for toxicity signs. - CYP450 inhibitors (e.g., cimetidine): may raise famotidine levels; adjust dose if needed.
