In clinical trials, amlodipine was given safely together with nitroglycerin, along with several other medicines. These included thiazide diuretics, beta blockers, ACE inhibitors, long-acting nitrates, Digoxin, Warfarin, nonsteroidal anti-inflammatory drugs, antibiotics, and oral hypoglycemic drugs.
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.
