Klacid

Clarithromycin, the active ingredient in Klacid, is a macrolide antibiotic presented as an oral dosage form for systemic use. It treats bacterial infections such as community‑acquired pneumonia, acute bacterial sinusitis, skin and soft‑tissue infections, and is used in combination regimens for Helicobacter pylori eradication.

GNH USA supplies Klacid as a licensed, GDP‑compliant international pharmaceutical supplier, providing the product to hospitals, pharmacies and clinics worldwide from its EU‑origin manufacturing network. All shipments comply with EU quality standards and are supported by comprehensive technical documentation.

Clarithromycin is a macrolide antibiotic used to treat bacterial infections in various organ systems.

- Community‑acquired pneumonia: eliminates the causative bacteria and improves respiratory function. - Acute bacterial sinusitis: reduces sinus inflammation and clears the infection. - Skin and soft‑tissue infections: eradicates susceptible Gram‑positive and some Gram‑negative organisms. - Helicobacter pylori eradication: part of combination therapy to achieve bacterial eradication and reduce ulcer recurrence.

Clarithromycin may cause a range of adverse reactions, from mild to severe.

Common Side Effects: - Nausea: mild to moderate upset stomach. - Diarrhea: frequent loose stools. - 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 or angioedema. - QT interval prolongation: risk of cardiac arrhythmias. - Clostridioides difficile-associated diarrhea: severe colitis. - Hepatotoxicity: elevated liver enzymes or hepatitis. - Stevens‑Johnson syndrome: severe skin reactions. - Cardiac arrhythmias: ventricular tachycardia or fibrillation.

Before prescribing clarithromycin, clinicians should consider several safety factors.

- Assess renal function: adjust use in severe impairment. - Monitor liver enzymes: watch for hepatotoxicity. - Avoid in known macrolide hypersensitivity: risk of severe allergy. - Caution in patients with QT prolongation risk: consider ECG monitoring. - Use in pregnancy only if benefit outweighs risk: limited data available. - Store at room temperature: keep in the original pack, protect from moisture.

Clarithromycin interacts with several medicines; awareness helps prevent adverse outcomes.

Major Interactions (Avoid): - Cisapride and pimozide: risk of serious cardiac arrhythmias. - Simvastatin and other CYP3A4 substrates: increased statin levels leading to myopathy. - Ergot alkaloids: risk of ergotism. - Colchicine: heightened toxicity. - Warfarin: enhanced anticoagulant effect.

Moderate Interactions (Monitor Closely): - Oral contraceptives: reduced efficacy, consider backup method. - Carbamazepine and phenytoin: decreased clarithromycin levels. - Digoxin: possible increase in serum concentration. - Theophylline: altered metabolism, monitor levels. - Antacids containing aluminum or magnesium: may affect absorption.
