Klacid

Clarithromycin, the active ingredient in Klacid, is a macrolide antibiotic presented as an oral tablet for oral use. It treats a range of bacterial infections, including community‑acquired pneumonia, acute bacterial sinusitis, bronchitis, 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. The company adheres to stringent quality standards and provides reliable efficient global logistics through consistent product availability.

Clarithromycin is used to treat bacterial infections across several organ systems and disease categories. - Community‑acquired pneumonia: eradicates susceptible Streptococcus pneumoniae and atypical pathogens, improving respiratory function. - Acute bacterial sinusitis: reduces bacterial load in sinus mucosa, relieving congestion and pain. - Acute bacterial bronchitis: resolves infection and associated cough in adults. - Skin and soft‑tissue infections: treats Staphylococcus aureus and Streptococcus pyogenes skin infections. - Helicobacter pylori eradication: used in combination regimens to eliminate H. pylori infection.

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

Common Side Effects: - Nausea - Diarrhea - Abdominal pain - Altered taste - Headache

Serious or Rare Side Effects: - Anaphylaxis or severe allergic reactions - QT interval prolongation leading to arrhythmias - Clostridioides difficile‑associated diarrhea or pseudomembranous colitis - Hepatic dysfunction or elevated liver enzymes

Before prescribing clarithromycin, clinicians should consider several precautionary measures to ensure safe use. - Assess renal function: adjust dose in severe impairment. - Monitor liver enzymes: use with caution in hepatic disease. - Review concomitant QT‑prolonging drugs: avoid additive cardiac risk. - Evaluate for known macrolide allergy: contraindicated if hypersensitivity. - Use during pregnancy only if benefit outweighs risk: limited safety data. - Store at room temperature: keep in original container, protect from moisture and light.

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

Major Interactions (Avoid): - Cisapride: risk of serious arrhythmia. - Pimozide: may cause QT prolongation. - Ergot alkaloids: risk of ergotism.

Moderate Interactions (Monitor Closely): - Antacids containing aluminum or magnesium: may lower clarithromycin absorption. - Warfarin: may increase INR, requiring coagulation monitoring. - Statins metabolized by CYP3A4 (e.g., simvastatin, lovastatin): may raise statin levels, monitor for myopathy.
