To lower the chance of getting cut, bruised, or injured, use caution with sharp objects like razors and nail cutters, and avoid activities such as contact sports.

This medicine may cause stomach bleeding. Daily use of alcohol while using this medicine will increase your risk for stomach bleeding. Limit alcoholic beverages. Ask your doctor or pharmacist about how much alcohol you may safely drink.
