Clarithromycin is a macrolide antibiotic used to treat bacterial infections of the respiratory tract, skin and gastrointestinal system.

- Community‑acquired pneumonia: eradicates the causative bacteria and improves clinical recovery. - Acute bacterial sinusitis: reduces sinus inflammation and clears infection. - Acute bacterial exacerbations of chronic bronchitis: shortens symptom duration and prevents complications. - Skin and soft‑tissue infections: eliminates pathogenic bacteria and promotes wound healing. - Helicobacter pylori eradication regimens: contributes to bacterial clearance when combined with other agents.

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

Common Side Effects: - Nausea: transient upset stomach. - Diarrhea: loose stools, often mild. - Abdominal pain: cramping or discomfort. - Taste disturbance: altered sense of taste. - Headache: mild to moderate. - Vomiting: occasional episodes.

Serious or Rare Side Effects: - Severe allergic reactions: rash, swelling, anaphylaxis. - Clostridioides difficile‑associated diarrhea: severe colitis. - Liver enzyme elevation: hepatitis or jaundice. - QT interval prolongation: risk of cardiac arrhythmias. - Cardiac arrhythmias: potentially life‑threatening rhythm disturbances.

Before prescribing clarithromycin, clinicians should consider several safety factors.

- Assess renal function: adjust use in severe impairment. - Monitor liver enzymes: caution in hepatic disease. - Avoid in known macrolide hypersensitivity: discontinue if reaction occurs. - Consider ECG monitoring: risk of QT prolongation. - Use during pregnancy only if benefits outweigh risks: consult obstetric guidance. - Store at room temperature: keep in original packaging, protect from moisture.

Clarithromycin interacts with several medicines; careful review is required.

Major Interactions (Avoid): - Cisapride: may cause life‑threatening arrhythmias. - Pimozide: increased risk of QT prolongation. - Theophylline: clarithromycin raises serum levels, leading to toxicity.

Moderate Interactions (Monitor Closely): - Warfarin: may increase INR; monitor coagulation parameters. - Carbamazepine: may reduce clarithromycin exposure; assess therapeutic response.
