Klerimed

Clarithromycin, the active ingredient in Klerimed, is a macrolide antibiotic presented as an oral dosage form for systemic use. It treats a range of bacterial infections, including respiratory, sinus, skin and soft‑tissue, and is used in Helicobacter pylori eradication regimens.

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

Clarithromycin is employed to treat infections caused by susceptible bacteria in several organ systems. - Community‑acquired pneumonia: effective in treating infection caused by susceptible respiratory pathogens. - Acute bacterial sinusitis: reduces sinus inflammation and clears bacterial infection. - Acute bacterial exacerbations of chronic bronchitis: shortens duration and severity of flare‑ups. - Skin and soft‑tissue infections: eradicates susceptible skin pathogens. - Helicobacter pylori eradication regimens: part of combination therapy to eliminate H. pylori infection.

Adverse reactions may occur with clarithromycin therapy.

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

Serious or Rare Side Effects: - Allergic reactions: rash, itching, swelling, or anaphylaxis. - QT interval prolongation: may lead to cardiac arrhythmias. - Severe hepatic dysfunction: jaundice or elevated liver enzymes. - Clostridioides difficile colitis: severe diarrhea with abdominal pain. - Stevens‑Johnson syndrome or toxic epidermal necrolysis: serious skin reactions.

Before initiating clarithromycin, consider the following safety measures. - Assess renal function: adjust use in patients with renal impairment. - Monitor liver enzymes: watch for hepatic toxicity during therapy. - Review cardiac history: avoid in patients with known QT prolongation. - Avoid in known hypersensitivity: discontinue if allergic reaction occurs. - Use with caution in pregnancy: benefits must outweigh potential risks. - Store at room temperature: keep in original container, protect from moisture.

Clarithromycin can interact with several medicines, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid): - QT‑prolonging agents (e.g., erythromycin, cisapride): increased risk of arrhythmia. - Strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole): may raise clarithromycin levels. - Antacids containing aluminum or magnesium: reduce clarithromycin absorption.

Moderate Interactions (Monitor Closely): - Warfarin: may enhance anticoagulant effect, monitor INR. - Oral contraceptives: possible reduction in contraceptive efficacy, advise backup method.
