Plavix warnings

• Because of the risk of bleeding, it is very important that any doctor, dentist, or other healthcare professional who treats you knows that you are taking Plavix.

• Your doctor may need to perform regular check-ups and lab tests to monitor your progress and detect side effects or complications. Keep all appointments while taking Plavix.

• Before starting clopidogrel, tell the prescriber if you are pregnant or breastfeeding. The prescriber should also know about all medical conditions you have or may have had, especially:

  • Any current bleeding problems like stomach ulcers

  • Any history of intestinal or stomach ulcers

  • Any history of bleeding problems or bleeding episodes

  • Any upcoming surgery or medical procedure, including dental procedures

  • Kidney disease

  • Heart failure

• Plavix is hazardous because it makes you bleed and bruise more easily. Once bleeding starts, it will take longer than usual to stop. Immediately contact the prescribing doctor or get medical help if you experience:

  • Unexplained bleeding or bruising

  • Bleeding that lasts a long time

  • Blood in the urine

  • Blood in the stools

  • Black and tarry stools 

  • Coughing or vomiting up blood or blood clots (“coffee grounds” vomit)

• To prevent unnecessary bleeding or bruising:

  • Take special care to avoid injury.

  • Avoid rough or risky activities.

  • Be gentle when brushing or flossing your teeth.

  • Avoid sharp objects. If you can’t avoid using a sharp object, be very careful.

• This medicine may cause a rare but serious blood clotting condition called thrombotic thrombocytopenic purpura (TTP).

• Do not stop taking Plavix until talking with the prescriber. Stopping the medicine too soon puts you at risk of heart attack or stroke.

• Keep Plavix out of the reach of children.
