What is Tiazac?

Tiazac is an oral medication made up of a calcium channel blocker called diltiazem. We carry the brand choice of this medication in 120mg, 180mg, 240mg, 300mg, and 360mg!

Tiazac is used to help treat hypertension. Uncontrolled hypertension (high blood pressure) can lead to a number of complications including heart attack or stroke, aneurysm, heart failure, dementia, metabolic syndrome and more. Tiazac is also used to help prevent angina. The severity and frequency of angina can be reduced using this medication.

Tiazac (diltiazem) is effective at treating high blood pressure and preventing angina because of its ability to relax your blood vessels, so blood may flow at a much easier pace. Tiazac (diltiazem) is also known to lower your heart rate, an effect that helps the heart work less and lowers your blood pressure, and helps prevent angina.

Your doctor will tell you before prescribing you Tiazac (diltiazem) exactly how to take this medication. Follow his or her directions very carefully, they can usually be found on the prescription label if you forget. Do not take this medication for longer than prescribed, or in smaller or larger amounts. Do not suddenly stop taking this medication. Keep up with frequent medical tests that are required while being treated with this medication.

This medication is taken by mouth, with or without food; usually taken once daily or as directed by your doctor. Make sure you are swallowing the capsules whole. Do not crush or chew on the capsules. Doing so may release the medication all at once and increases the possibilities of side effects. If you are taking this medicine to treat angina, keep in mind that it should not be used to treat an angina attack; this medication will only help prevent them from occurring.


Do not use Tiazac (diltiazem)

Do not use this medication if you are allergic to diltiazem, or if you have a serious heart condition without a pacemaker, very low blood pressure, or if you have recently had a heart attack followed by a buildup of fluid in your lungs.

What is Diltiazem?

This medication is used to prevent a chest pain known as angina, and it is also used to treat high blood pressure. When taking this medication, it may help you increase your ability to exercise and decrease the amount of times you get angina attacks. For hypertension, lowering your blood pressure may also reduce your risk of strokes, heart attacks, and kidney problems. Diltiazem belongs to a group of drugs called calcium channel blockers. Basically, what it does is relaxes the blood vessels in your body and heart, which in turn lowers your heart rate. This allows the blood to flow more freely without your heart working overboard. This medication can be purchased in five different strengths which are 120mg, 180mg, 240mg, 300mg, and 360mg.
