Klacid Sr

Clarithromycin, the active ingredient in Klacid Sr, is a macrolide antibiotic presented as an oral tablet for systemic use. It treats a range of bacterial infections in adults and children when prescribed by a healthcare professional. The drug works by inhibiting bacterial protein synthesis, making it effective against common respiratory, sinus, skin and certain gastrointestinal pathogens. It is approved for use in the European Union and is available by prescription.

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

Clarithromycin is used to treat bacterial infections affecting the respiratory, sinus, skin and gastrointestinal systems.

- Community‑acquired pneumonia: eradicates susceptible organisms and improves respiratory function. - Acute bacterial sinusitis: reduces sinus inflammation and clears infection. - Skin and soft‑tissue infections: resolves cellulitis, erysipelas and other bacterial skin conditions. - Helicobacter pylori eradication (in combination therapy): contributes to bacterial clearance as part of triple‑therapy regimens. - Mycobacterial infections: used in selected cases of atypical mycobacterial disease.

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

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 to moderate intensity. - Vomiting: occasional episodes.

Serious or Rare Side Effects: - Severe allergic reactions (anaphylaxis): rash, swelling, difficulty breathing. - QT interval prolongation: risk of cardiac arrhythmias. - Hepatic dysfunction: elevated liver enzymes or jaundice. - Clostridioides difficile‑associated diarrhea: severe colitis. - Stevens‑Johnson syndrome/toxic epidermal necrolysis: extensive skin blistering. - Cardiac arrhythmias: ventricular tachycardia or fibrillation.

When prescribing clarithromycin, clinicians should consider several precautionary measures to ensure safe use.

- Assess renal and hepatic function: adjust therapy if impairment is present. - Monitor for QT prolongation: avoid in patients with known cardiac conduction disorders. - Review concomitant medications: avoid drugs that may cause dangerous interactions. - Check for hypersensitivity: discontinue if allergic reaction occurs. - Use in pregnancy only if benefits outweigh risks: consult obstetric guidance. - Store at ambient temperature: keep in the original pack, protect from moisture and direct sunlight.

Clarithromycin interacts with several medicines; understanding the level of interaction guides clinical decisions.

Major Interactions (Avoid): - Strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole): may increase clarithromycin levels. - Drugs that prolong QT interval (e.g., cisapride, pimozide): risk of serious arrhythmias. - Ergot alkaloids (e.g., ergotamine): can cause ergot toxicity.

Moderate Interactions (Monitor Closely): - Statins metabolized by CYP3A4 (e.g., simvastatin, lovastatin): monitor for myopathy. - Warfarin: may enhance anticoagulant effect, check INR. - Theophylline and carbamazepine: may reduce their plasma concentrations.
