Ask your doctor before taking a nonsteroidal anti-inflammatory drug (NSAID) such as aspirin, ibuprofen (Advil, Motrin), naproxen (Aleve), celecoxib, diclofenac, indomethacin, meloxicam, and others. Using an NSAID with heparin may cause you to bruise or bleed easily.
Tell your doctor about all your other medicines, especially:
a blood thinner - warfarin, Coumadin, Jantoven;
digitalis;
tetracyclines;
nicotine; or
antihistamines.
