Toradol (ketorolac) is a nonsteroidal anti-inflammatory drug (NSAID). Ketorolac works by reducing hormones that cause inflammation and pain in the body.   Toradol is used short-term (5 days or less) to treat moderate to severe pain. Warnings You should not use Toradol if you have any active or recent bleeding (including bleeding inside your body), a head injury, a stomach ulcer, severe kidney disease, a bleeding or blood-clotting disorder, a history of severe allergic reaction to aspirin or an NSAID, or if you are scheduled to have surgery.   Do not use Toradol if you are in your third trimester of pregnancy or if you are breast-feeding a baby.   You should not use ketorolac if you also take pentoxifylline, probenecid, aspirin, or other NSAID drugs (which may include ibuprofen, acetaminophen, naproxen, celecoxib, diclofenac, indomethacin, meloxicam, and others and others).   Ketorolac may also cause stomach or intestinal bleeding, which can be fatal. These conditions can occur without warning while you are using this medicine, especially in older adults. You should not take this medicine if you already have bleeding in your stomach or intestines.   Do not drink alcohol while taking Toradol. Alcohol can increase the risk of stomach bleeding caused by ketorolac. Before taking this medicine Toradol can increase your risk of fatal heart attack or stroke, especially if you use it long term or take high doses, or if you have heart disease. Do not use this medicine just before or after heart bypass surgery (coronary artery bypass graft, or CABG).   You should not use Toradol if you are allergic to ketorolac, or if you have: active or recent stomach ulcer, stomach bleeding, or intestinal bleeding; a bleeding or blood-clotting disorder; a closed head injury or bleeding in your brain; bleeding from a recent surgery; severe kidney disease or dehydration; a history of asthma or severe allergic reaction after taking aspirin or an NSAID; if you are scheduled to have surgery (especially bypass surgery); or if you are in late pregnancy or you are breast-feeding a baby.
