donotDo not use this medication if you are allergic to aspirin, or if you have:
  • a recent history of stomach or intestinal bleeding;
  • a bleeding disorder such as hemophilia; or
  • an allergy to an NSAID (non-steroidal anti-inflammatory drug) such as Advil, Motrin, Aleve, Orudis, Indocin, Lodine, Voltaren, Toradol, Mobic, Relafen, Feldene, and others.

Before taking aspirin, tell your doctor if you are allergic to any drugs, or if you have:

  • stomach ulcers;
  • liver disease;
  • kidney disease;
