Indications
Tiazac, also known as diltiazem ER, is a medication used to treat conditions such as high blood pressure (hypertension) and chronic stable angina. Diltiazem belongs to a class of drugs called calcium channel blockers.
Tiazac works by relaxing the muscles in the blood vessels, which allows for better blood flow and lowers blood pressure. It also helps to reduce the workload on the heart by slowing down the heart rate. Tiazac is available in extended-release capsules and is usually taken once per day. Tiazac must be consumed regularly to prevent angina. Do not use it to treat angina when it occurs.
Uses and Dosage
Tiazac is an Extended-Release Capsule that should be taken by mouth, with or without food, usually once daily or as per the directions given by your doctor. Swallow the capsules whole. Do not crush or chew them, as doing so can release all the drugs at once, which may increase your risk of side effects.
In case you have difficulty swallowing the capsule, you may open the capsule and carefully sprinkle its contents on a spoonful of soft, cool applesauce just before taking it. You should swallow all the drug/food mixture right away and not chew it. After taking the drug, rinse your mouth and swallow the rinse liquid to ensure that you have swallowed all the medicine. However, do not prepare a supply in advance.
