Plavix (clopidogrel) keeps the platelets in your blood from coagulating (clotting) to prevent unwanted blood clots that can occur with certain heart or blood vessel conditions.
Plavix is used to prevent blood clots after a recent heart attack or stroke, and in people with certain disorders of the heart or blood vessels.
Plavix may also be used for purposes not listed in this medication guide.
Important information
Plavix keeps your blood from coagulating (clotting) to prevent unwanted blood clots that can occur with certain heart or blood vessel conditions. Because of this drug action, Plavix can make it easier for you to bleed, even from a minor injury.
Your doctor will perform blood tests to make sure you do not have certain genetic conditions that would prevent you from safely using Plavix.
You should not use Plavix if you have any active bleeding such as a stomach ulcer or bleeding in the brain (such as from a head injury).
Some medicines can interact with clopidogrel and should not be used at the same time. Your doctor may need to change your treatment plan if you also take other medicines, especially certain stomach acid reducers (esomeprazole, omeprazole, Nexium, Prilosec).
If you need surgery or dental work, tell the surgeon or dentist ahead of time that you take Plavix.
