Klacid Forte

Clarithromycin, the active ingredient in Klacid Forte, is a macrolide antibiotic presented as an oral tablet for oral use. It treats bacterial infections such as community‑acquired pneumonia, acute bacterial sinusitis, and skin infections in adults and children as prescribed.

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

Klacid Forte is a macrolide antibiotic indicated for several bacterial infections affecting the respiratory and skin systems.

Community‑acquired pneumonia: eradicates the causative bacteria, improving respiratory function and reducing disease duration. Acute bacterial sinusitis: clears sinus infection, relieving congestion and facial pain. Acute exacerbations of chronic bronchitis: reduces bacterial load, helping to restore normal breathing. Skin and soft tissue infections: eliminates pathogenic bacteria, promoting wound healing. Helicobacter pylori eradication: part of combination therapy to eradicate H. pylori and aid ulcer healing.

Common Side Effects: - Nausea: mild to moderate stomach upset. - Diarrhea: loose stools, often transient. - Abdominal pain: cramping or discomfort. - Taste disturbance: altered or metallic taste. - Headache: mild to moderate. - Vomiting: occasional episodes.

Serious or Rare Side Effects: - Severe allergic reactions: anaphylaxis, rash, swelling. - QT interval prolongation: risk of cardiac arrhythmias. - Hepatic dysfunction: elevated liver enzymes or hepatitis. - Clostridioides difficile-associated diarrhea: severe colitis. - Stevens‑Johnson syndrome: serious skin reaction. - Neutropenia: reduced white blood cell count.

Before initiating therapy, consider the following precautions: - Assess renal and hepatic function: adjust therapy if impairment is present. - Known hypersensitivity: avoid in patients with macrolide allergy. - Cardiac risk: monitor QT interval in patients with existing heart conditions. - Concomitant QT‑prolonging drugs: use with caution to prevent arrhythmias. - Pregnancy and lactation: prescribe only if benefits outweigh potential risks. - Severe hepatic impairment: consider dose reduction or alternative therapy. - Store at ambient temperature: keep in the original pack, protect from moisture.

Clarithromycin may interact with several medications, requiring careful management.

Major Interactions (Avoid): - Erythromycin and other macrolides: additive QT prolongation. - Cisapride: increased risk of serious arrhythmias. - Pimozide: elevated plasma concentrations leading to toxicity. - Terfenadine: risk of cardiac events. - Statins metabolized by CYP3A4 (e.g., simvastatin): heightened myopathy risk.

Moderate Interactions (Monitor Closely): - Warfarin: possible increase in INR and bleeding risk. - Theophylline: clarithromycin can raise theophylline levels. - Carbamazepine: may reduce clarithromycin efficacy. - Oral contraceptives: potential reduction in contraceptive effectiveness. - Antacids containing aluminum or magnesium: may decrease clarithromycin absorption.
