Telmitan Max Amlodipine Besilate + Telmisartan Cimetidine
ModerateThe leaflet text doesn't describe any interaction between amlodipine with telmisartan and cimetidine. Telmisartan isn't broken down by the cytochrome P450 system and, apart from some inhibition of CYP2C19, had no effect on those enzymes in laboratory tests. So it isn't expected to interact with drugs that inhibit or are metabolized by cytochrome P450 enzymes, except that it may slow the breakdown of drugs metabolized by CYP2C19.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
