Product Informationexpand all collapse all
Generic Cardizem is used to treat angina (chest pain) or high blood pressure. Diltiazem is also used sometimes to treat Raynaud's syndrome. Talk to your doctor about the possible risks of using this drug for your condition. If taken regularly, Diltiazem controls chest pain, but it does not stop chest pain once it starts. Your doctor may give you a different medication to take when you have chest pain. Diltiazem controls high blood pressure and chest pain (angina) but does not cure them.
How to take
Take Generic Cardizem exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
Your doctor may occasionally change your dose to make sure you get the best results.
Take Generic Cardizem with a full glass of water. Do not crush, chew, break, or open an extended-release tablet or capsule. Swallow it whole. Breaking or opening the pill may cause too much of the drug to be released at one time.

Jake F., 45, Illinos Standard ED Pack (Generic)
“My ED was giving me nightmares! Yes, I could use Viagra but it was too expensive to buy all the time. That’s why I ordered a generic version at Canadian Pharmacy and could not be happier with the results.”
Janine L., 35, Winnipeg Albuterol
“What I like most about this pharmacy is that they deliver very fast and always package it securely so no one knows what I ordered. It is a big deal for someone who has very nosy neighbours.”
