Before taking clopidogrel,
tell your doctor and pharmacist if you are allergic to clopidogrel, prasugrel (Effient), ticlopidine (Ticlid), any other medications, or any ingredient in clopidogrel tablets. Ask your pharmacist or check the Medication Guide for a list of the ingredients.
tell your doctor and pharmacist what other prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention any of the following: anticoagulants ('blood thinners') such as warfarin (Coumadin, Jantoven); aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen (Advil, Motrin), and naproxen (Aleve, Naprosyn); cilostazol; esomeprazole (Nexium); etravirine (Intelence); omeprazole (Prilosec, Prilosec OTC, Zegerid); repaglinide (Prandin, in Prandimet); selective serotonin reuptake inhibitors (SSRIs) such as citalopram (Celexa), escitalopram (Lexapro), fluoxetine (Prozac, Sarafem, in Symbyax), fluvoxamine (Luvox), paroxetine (Paxil), and sertraline (Zoloft); and selective serotonin/norepinephrine reuptake inhibitors (SNRIs) such as desvenlafaxine (Khedezla, Pristiq), duloxetine (Cymbalta), sibutramine (no longer available in the U.S.; Meridia), and venlafaxine (Effexor). Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
tell your doctor if you have bleeding ulcers (sores in the lining of the stomach or small intestine that are bleeding), bleeding in the brain, or any other condition that causes severe bleeding. Your doctor may tell you that you should not take clopidogrel.
tell your doctor if you have recently been injured and if you have or have ever had liver or kidney disease or any condition that may cause bleeding, including stomach problems such as ulcers and certain eye problems.
tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking clopidogrel, call your doctor.
if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking clopidogrel. Your doctor may tell you to stop taking clopidogrel at least 5 days prior to your surgery to avoid excessive bleeding during surgery. Your doctor will tell you when to start taking clopidogrel again after your surgery.
you should know that you may bleed more easily or for a longer time than usual while you are taking clopidogrel. Be careful not to cut or hurt yourself while you are taking clopidogrel.
