CONTRAINDICATION:

• Hypersensitivity to macrolide antibiotic drugs or any of its excipients.

• Concomitant administration of clarithromycin and any of the following drugs is contraindicated: astemizole, cisapride, pimozide, terfenadine as this may result in QT prolongation and cardiac arrhythmias including ventricular tachycardia, ventricular fibrillation, and torsades de pointes.

• Concomitant administration of clarithromycin and ergot alkaloids (e.g., ergotamine or dihydroergotamine) is contraindicated, as this may result in ergot toxicity.

• Clarithromycin should not be used in patients who suffer from severe hepatic failure in combination with renal impairment.

• Clarithromycin should not be used concomitantly with HMG-CoA reductase inhibitors (statins) that are extensively metabolized by CYP3A4 (lovastatin or simvastatin), due to the increased risk of myopathy, including rhabdomyolysis.

• Clarithromycin (and other strong CYP3A4 inhibitors) should not be used concomitantly with colchicine.

• As the dose cannot be reduced from 500 mg once-daily, clarithromycin modified release is contraindicated in patients with creatinine clearance less than 30 mL/min. Clarithromycin immediate release tablets may be utilized in this patient population.
