Diltiazem: Uses, Side Effects, and Drug Interactions
Brand names: diltiazem hydrochloride
# Diltiazem: What You Need to Know Diltiazem is a medicine that helps your heart work better and keeps your blood pressure under control. Doctors prescribe it to treat high blood pressure and certain heart rhythm problems. It works by relaxing the blood vessels in your body, which allows blood to flow more easily and reduces the strain on your heart. This medicine is especially helpful for people whose hearts work too hard or whose blood vessels are too tight. Before taking diltiazem, it's important to tell your doctor about all the other medicines you're taking, because diltiazem can interact with some drugs. Never take it with certain heart medicines without your doctor's approval, as combining them could cause problems with your heart's rhythm or how hard it beats. You should also let your doctor know if you're pregnant, nursing, or have any serious health conditions. Like all medicines, diltiazem can cause side effects, so always take it exactly as your doctor prescribes and attend follow-up appointments to make sure it's working safely for you.
