What is clopidogrel?

Clopidogrel is used to lower your risk of having a stroke, blood clot, or serious heart problem after you've had a heart attack, severe chest pain (angina), or circulation problems.

Clopidogrel may also be used for purposes not listed in this medication guide.

What should I discuss with my healthcare provider before taking clopidogrel?

• any active bleeding; or
• a stomach ulcer or bleeding in the brain (such as from a head injury).

Tell your doctor if you have ever had:

• an ulcer in your stomach or intestines; or
• a bleeding disorder or blood clotting disorder.

Clopidogrel may not work as well if you have certain genetic factors that affect the breakdown of this medicine in your body. Your doctor may perform a blood test to make sure clopidogrel is right for you.

This medicine is not expected to harm an unborn baby. However, taking clopidogrel within 1 week before childbirth can cause bleeding in the mother. Tell your doctor if you are pregnant or plan to become pregnant.

How should I take clopidogrel?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use these medicines exactly as directed.

Clopidogrel can be taken with or without food.

Clopidogrel is sometimes taken together with aspirin. Take aspirin only if your doctor tells you to.

You may need to stop using clopidogrel for a short time before a surgery, medical procedure, or dental work. Any healthcare provider who treats you should know that you are taking clopidogrel.

What happens if I miss a dose?

Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.

What happens if I overdose?

What should I avoid while taking clopidogrel?

Avoid activities that may increase your risk of bleeding or injury. Use extra care to prevent bleeding while shaving or brushing your teeth.

What other drugs will affect clopidogrel?

Sometimes it is not safe to use certain medications at the same time. Some drugs can affect your blood levels of other drugs you take, which may increase side effects or make the medications less effective.

Tell your doctor about all your other medicines, especially:

• a stomach acid reducer such as omeprazole, Nexium, or Prilosec;
• an antidepressant such as citalopram, fluoxetine, sertraline, Cymbalta, Effexor, Lexapro, Pristiq, or Prozac;
• rifampin;
• a blood thinner --warfarin, Coumadin, Jantoven; or
• NSAIDs (nonsteroidal anti-inflammatory drugs) --aspirin, ibuprofen (Advil, Motrin), naproxen (Aleve), celecoxib, diclofenac, indomethacin, meloxicam, and others.
