What Experts Say

Clarithromycin is a semi synthetic macrolide that binds the bacterial 50S ribosomal subunit and halts protein synthesis, giving it broad activity against gram positive bacteria and several atypical respiratory pathogens. This mechanism underlies its use both as a standalone respiratory antibiotic and as one arm of triple therapy for H. pylori.

Physicians pair clarithromycin with a proton pump inhibitor and a second antibiotic, usually amoxicillin or metronidazole, when treating H. pylori linked peptic ulcer disease, since single agent therapy fails to clear this organism reliably. The 250mg tablet strength allows flexible twice daily dosing across both indications.

Because clarithromycin strongly inhibits the CYP3A4 liver enzyme, doctors review a patient's full medicine list before prescribing it, particularly statins, warfarin and certain heart rhythm drugs. This interaction profile, along with a rare risk of QT prolongation, is why the tablet remains a prescription only antibiotic rather than an over the counter option.

• Digoxin: clarithromycin can raise digoxin blood levels
• Theophylline: clarithromycin can raise theophylline blood levels
• Cisapride, pimozide or ergot medicines: combination is avoided due to risk of fatal heart rhythm disturbances

Risks and warnings

• Allergy history: avoid in patients with known hypersensitivity to clarithromycin, erythromycin or other macrolides
• Heart rhythm risk: use with caution in patients with QT prolongation, electrolyte imbalance or on other QT prolonging medicines
• Liver disease: rare but serious liver enzyme elevation and hepatitis have been reported, use caution in existing liver impairment
• Kidney disease: dose adjustment is needed in significant renal impairment
• Pregnancy and breastfeeding: use only if clearly needed and advised by a doctor
• Myasthenia gravis: clarithromycin can worsen muscle weakness in this condition
• Contraindicated combinations: not to be used with cisapride, pimozide or ergot alkaloids due to risk of serious heart rhythm problems
