Klacid

Clarithromycin, the active ingredient in Klacid, is a macrolide antibiotic presented as tablets for oral use. It treats a range of bacterial infections, including community‑acquired pneumonia, acute bacterial sinusitis, skin and soft‑tissue infections, and is part of combination therapy for Helicobacter pylori eradication.

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

Klacid, a macrolide antibiotic, is employed to treat bacterial infections affecting the respiratory tract, sinuses, skin and gastrointestinal system. - Community‑acquired pneumonia: eliminates the responsible pathogens and facilitates recovery of lung function. - Acute bacterial sinusitis: reduces sinus inflammation by eradicating the infecting bacteria. - Skin and soft‑tissue infections: clears bacterial involvement in cellulitis, abscesses and wound infections. - Helicobacter pylori eradication (in combination therapy): contributes to bacterial clearance as part of a multi‑drug regimen for ulcer disease.

Adverse reactions may occur with clarithromycin therapy and are categorized by frequency and severity.

Common Side Effects: - Nausea: mild to moderate stomach upset. - Diarrhea: loose stools, sometimes watery. - Abdominal pain: cramping or discomfort. - Taste disturbance: altered or metallic taste. - Headache: mild, transient. - Rash: mild skin erythema.

Serious or Rare Side Effects: - Hepatotoxicity: elevated liver enzymes or jaundice. - QT prolongation: cardiac rhythm disturbances. - Severe allergic reactions: anaphylaxis, angioedema. - Clostridioides difficile colitis: severe diarrhea due to bacterial overgrowth.

Before initiating clarithromycin, consider the following safety measures. - Assess liver function: avoid use in patients with severe hepatic impairment. - Review cardiac history: caution in individuals with known QT prolongation or arrhythmias. - Evaluate drug interactions: check for concomitant use of CYP3A4 substrates. - Monitor renal function: adjust therapy in severe renal impairment if needed. - Pregnancy and breastfeeding: use only if the potential benefit outweighs risk. - Store at ambient temperature: keep below 25 °C, retain in original packaging, protect from moisture.

Clarithromycin can affect the metabolism of several co‑administered medicines.

Major Interactions (Avoid): - Simvastatin: risk of severe myopathy; avoid concurrent use. - Pimozide: may cause cardiac toxicity; contraindicated. - Cisapride: can precipitate QT prolongation; avoid.

Moderate Interactions (Monitor Closely): - Warfarin: may increase INR; monitor coagulation parameters. - Carbamazepine: clarithromycin can raise carbamazepine levels; observe for toxicity. - Theophylline: possible increased serum concentrations; adjust dose if needed.
