Medication Guide 

Clopidogrel Tablets USP 

Read this Medication Guide before you start taking clopidogrel and each time you get a refill. There may be new information. This Medication Guide does not take the place of talking with your doctor about your medical condition or your treatment.  

What is the most important information I should know about clopidogrel?  

1. Clopidogrel may not work as well in people who:  

• have certain genetic factors that affect how the body breaks down clopidogrel. Your doctor may do genetic tests to make sure clopidogrel is right for you.
• take certain medicines, especially omeprazole (Prilosec®) or esomeprazole (Nexium®). Your doctor may change the medicine you take for stomach acid problems while you take clopidogrel.  

2. Clopidogrel can cause bleeding which can be serious and can sometimes lead to death. clopidogrel is a blood thinner medicine that lowers the chance of blood clots forming in your body. While you take clopidogrel:

• you may bruise and bleed more easily
• you are more likely to have nose bleeds
• it will take longer for any bleeding to stop  

Call your doctor right away if you have any of these signs or symptoms of bleeding:

• unexpected bleeding or bleeding that lasts a long time
• blood in your urine (pink, red or brown urine)
• red or black stools (looks like tar)
• bruises that happen without a known cause or get larger
• cough up blood or blood clots
• vomit blood or your vomit looks like coffee grounds  

Do not stop taking clopidogrel without talking to the doctor who prescribes it for you. People who are treated with a stent, and stop taking clopidogrel too soon, have a higher risk of getting a blood clot on the stent, having a heart attack, or dying. If you must stop clopidogrel because of bleeding, your risk of a heart attack may be higher.  

What is clopidogrel?  

Clopidogrel is a prescription medicine used to treat people who have any of the following:

• chest pain due to heart problems
• poor circulation in their legs (peripheral arterial disease)
• a heart attack a stroke  

Clopidogrel is used alone or with aspirin to lower your chance of having another serious problem with your heart or blood vessels such as heart attack, stroke, or blood clot that can lead to death. 

Platelets are blood cells that help your blood clot normally. Clopidogrel helps to prevent platelets from sticking together and forming a clot that can block an artery.  

It is not known if clopidogrel is safe and effective in children.
