Your doctor or pharmacist can often prevent or manage interactions by changing how you use your medications or by close monitoring.To help your doctor and pharmacist give you the best care, be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products) before starting treatment with this product. While using this product, do not start, stop, or change the dosage of any other medicines you are using without your doctor's approval.Some products that may interact with this drug include: anti-seizure drugs (e.g., carbamazepine, phenobarbital, phenytoin), digoxin, ergot drugs (e.g., dihydroergotamine, ergotamine), ivabradine, live bacterial vaccines (e.g., typhoid or cholera vaccines), metoprolol, rifampin, certain "statin" drugs for high cholesterol (atorvastatin, lovastatin, simvastatin), St John's wort, theophylline, warfarin, drugs removed from your system by certain liver enzymes (CYP 3A4 substrates such as colchicine, cyclosporine, eplerenone, midazolam, sildenafil, sirolimus, tacrolimus, triazolam).Many drugs besides telithromycin may affect the heart rhythm (QT prolongation), including amiodarone, cisapride, dofetilide, pimozide, procainamide, quinidine, sotalol, macrolide antibiotics (such as erythromycin), among others.
