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.

You should not use clopidogrel if you have any active bleeding such as a stomach ulcer or bleeding in the brain.

Clopidogrel increases your risk of bleeding, which can be severe or life-threatening. Call your doctor or seek emergency medical attention if you have bleeding that will not stop, if you have blood in your urine, black or bloody stools, or if you cough up blood or vomit that looks like coffee grounds.

Do not stop taking clopidogrel without first talking to your doctor, even if you have signs of bleeding. Stopping clopidogrel may increase your risk of a heart attack or stroke.

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.

Clopidogrel keeps your blood from coagulating (clotting) and can make it easier for you to bleed, even from a minor injury. Contact your doctor or seek emergency medical attention if you have any bleeding that will not stop.

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.

Do not stop taking clopidogrel without first talking to your doctor, even if you have signs of bleeding. Stopping the medicine could increase your risk of a heart attack or stroke.

Store at room temperature away from moisture and heat.

You should not use clopidogrel if you are allergic to it, or if you have:

Tell your doctor if you have ever had:

• an ulcer in your stomach or intestines; or

• a bleeding disorder or blood clotting disorder.

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.

You should not breastfeed while using this medicine.

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.

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. Overdose can cause excessive bleeding.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

Unless your doctor tells you otherwise, continue your normal diet.

Avoid alcohol. It can increase your risk of stomach bleeding.

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

If you also take aspirin: Ask a doctor or pharmacist before using medicines for pain, fever, swelling, or cold/flu symptoms. They may contain ingredients similar to aspirin (such as salicylates, ibuprofen, ketoprofen, or naproxen). Taking these products together can increase your risk of bleeding.

Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
