Azithromycin is a macrolide antibiotic that acts on a range of bacterial infections.

- Community‑acquired pneumonia: helps reduce bacterial load and speeds the recovery of patients. - Uncomplicated skin and soft‑tissue infections: provides bacterial eradication leading to clinical improvement. - Uncomplicated genital chlamydia infection: eliminates the causative organism, achieving microbiological cure. - Acute bacterial sinusitis: shortens symptom duration and promotes resolution. - Acute pharyngitis due to Streptococcus pyogenes: reduces symptom severity and duration.

Azithromycin may produce a range of adverse reactions, most of which are mild and reversible.

Common Side Effects: - Gastrointestinal upset: nausea, abdominal cramping and vomiting. - Diarrhea: often mild and self‑limiting. - Headache: transient and usually resolves without intervention. - Taste alteration: a temporary metallic or bitter taste. - Rash: mild erythematous skin eruption.

Serious or Rare Side Effects: - QT‑interval prolongation: may predispose to cardiac arrhythmias. - Severe allergic reactions: anaphylaxis, angio‑edema, or Stevens‑Johnson syndrome. - Hepatotoxicity: elevated liver enzymes or clinically apparent hepatitis. - Clostridioides difficile infection: severe colitis following disruption of gut flora. - Visual disturbances: rare reports of blurred vision or photophobia.

When prescribing Azithromycin, clinicians should consider several safety aspects.

- Assess renal and hepatic function: adjust dosing in patients with significant impairment. - Review cardiac history: avoid in patients with known QT prolongation or arrhythmias. - Evaluate for drug allergies: contraindicate if the patient has a known macrolide hypersensitivity. - Monitor for gastrointestinal disease: use cautiously in patients with inflammatory bowel disease. - Counsel on pregnancy and lactation: discuss potential risks and benefits with the prescriber. - Store at ambient temperature: keep in the original container, protect from moisture and heat.

Azithromycin can interact with several medicines, affecting its safety or efficacy.

Major Interactions (Avoid): - Antacids containing aluminum or magnesium: reduce azithromycin absorption. - Drugs that prolong QT interval (e.g., quinidine, sotalol): increase risk of cardiac arrhythmias. - Digoxin: may increase serum digoxin concentrations.

Moderate Interactions (Monitor Closely): - Warfarin: may enhance anticoagulant effect, requiring INR monitoring. - Statins (especially simvastatin): increased risk of myopathy. - Oral contraceptives: potential reduction in contraceptive efficacy. - Rifampicin: may lower azithromycin plasma levels. - Cyclosporine: increased risk of nephrotoxicity.
