Plavix Oral Precautions
Before taking clopidogrel, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.
Before using this medication, tell your doctor or pharmacist your medical history, especially of:
- bleeding conditions (such as stomach ulcers, bleeding in the brain/eye)
- recent surgery
- serious injury/trauma
- liver disease
- bleeding disease (such as hemophilia)
While you are taking this medication, it may take longer than usual for bleeding to stop if you have a cut or injury. Use caution with sharp objects like safety razors or nail cutters and avoid activities such as contact sports to lower the chance of getting cut, bruised, or injured.
Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). Your doctor may instruct you to stop clopidogrel for 5 to 7 days before surgery. Do not stop taking clopidogrel without talking with your heart doctor (cardiologist) first.
Limit alcoholic beverages. Daily use of alcohol, especially when combined with this medicine, may increase your risk for stomach bleeding.
During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.
