Klacid

Clarithromycin, the active ingredient in Klacid, is a macrolide antibiotic presented as an oral dosage form for oral use. It treats bacterial infections of the respiratory tract, skin and soft tissues, and is used in combination therapy for Helicobacter pylori infection.

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

Klacid is a macrolide antibiotic that targets bacterial infections in several organ systems.

Respiratory tract infections: eradicates susceptible pathogens and improves clinical symptoms. Skin and soft tissue infections: reduces bacterial load and promotes healing. Helicobacter pylori infection: used in combination regimens to achieve eradication.

Common adverse reactions are reported with clarithromycin therapy.

Common Side Effects: - Nausea: mild to moderate gastrointestinal upset. - Diarrhea: loose stools, sometimes watery. - Abdominal pain: cramping or discomfort. - Altered taste: metallic or bitter sensation. - Headache: mild to moderate intensity. - Vomiting: occasional episodes.

Serious or Rare Side Effects: - Anaphylaxis: severe allergic reaction requiring immediate medical attention. - QT interval prolongation: may predispose to cardiac arrhythmias. - Hepatic dysfunction: elevated liver enzymes or hepatitis. - Clostridioides difficile-associated diarrhea: severe colitis. - Stevens‑Johnson syndrome/toxic epidermal necrolysis: life‑threatening skin reactions. - Cardiac arrhythmias: including torsades de pointes.

Before initiating Klacid, clinicians should consider several safety aspects.

Assess liver function: monitor hepatic enzymes in patients with pre‑existing liver disease. Monitor cardiac QT interval: avoid in patients with known prolongation or concurrent QT‑prolonging drugs. Use with caution in renal impairment: dose adjustment may be required. Avoid in known macrolide allergy: discontinue if hypersensitivity occurs. Review concomitant medications: assess for interactions that affect clarithromycin metabolism. Store at room temperature: keep in the original packaging, protect from moisture and direct sunlight.

Clarithromycin interacts with several drug classes that can alter safety or efficacy.

Major Interactions (Avoid): - Cisapride: risk of severe QT prolongation. - Pimozide: can cause life‑threatening arrhythmias. - Ergot alkaloids: may precipitate ergotism. - Simvastatin/Lovastatin: increased risk of myopathy. - Colchicine: heightened toxicity, especially in renal dysfunction.

Moderate Interactions (Monitor Closely): - Oral contraceptives: reduced efficacy, consider backup method. - Carbamazepine: decreased clarithromycin levels. - Phenytoin: may lower plasma concentrations. - Rifampin: induces metabolism, reducing effectiveness. - Digoxin: increased serum levels, monitor for toxicity.
