What is ketorolac?
Ketorolac is a nonsteroidal anti-inflammatory drug (NSAID). Ketorolac works by reducing hormones that cause inflammation and pain in the body.
Ketorolac is used short-term (5 days or less) to treat moderate to severe pain.
Ketorolac may also be used for purposes not listed in this medication guide.
You should not use ketorolac 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, if you are scheduled to have surgery, if you are in late pregnancy, or if you are breast-feeding a baby.
Ketorolac 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 ketorolac just before or after heart bypass surgery (coronary artery bypass graft, or CABG).
Ketorolac may also cause stomach or intestinal bleeding, which can be fatal. These conditions can occur without warning while you are using ketorolac, especially in older adults. You should not take this medicine if you already have bleeding in your stomach or intestines.
Before taking this medicine
Ketorolac 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. Even people without heart disease or risk factors could have a stroke or heart attack while taking this medicine.
Do not use this medicine just before or after heart bypass surgery (coronary artery bypass graft, or CABG).
Ketorolac may also cause stomach or intestinal bleeding, which can be fatal. These conditions can occur without warning while you are using ketorolac, especially in older adults.
You should not use ketorolac if you are allergic to it, 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.
Some medicines can cause unwanted or dangerous effects when used with ketorolac. Your doctor may need to change your treatment plan if you use any of the following drugs:
To make sure ketorolac is safe for you, tell your doctor if you have ever had:
a heart attack, stroke, or blood clot;
stomach ulcers or bleeding;
kidney disease (or if you are on dialysis);
Using ketorolac during the last 3 months of pregnancy may harm the unborn baby. Ketorolac may also increase the risk of uterine bleeding and is not for use during labor and delivery. Tell your doctor if you are pregnant.
Ketorolac can pass into breast milk and may harm a nursing baby. Do not breast-feed while using this medicine.
Ketorolac is not approved for use by anyone younger than 2 years old.
How should I take ketorolac?
Ketorolac is usually given first as an injection, and then as an oral (by mouth) medicine. The injection is given into a muscle, or into a vein through an IV. A healthcare provider will give you the injection.
Follow all directions on your prescription label. Do not take ketorolac in larger amounts or for longer than recommended. Use the lowest dose that is effective in treating your condition.
Ketorolac should not be used for longer than 5 days, including both injection plus tablets. Long-term use of this medicine can damage your kidneys or cause bleeding.
Store at room temperature away from moisture, heat, and light. Keep the bottle tightly closed when not in use.
Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.
What happens if I miss a dose?
Since ketorolac is used for pain, you are not likely to miss a dose. Skip any missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
What should I avoid while taking ketorolac?
Avoid drinking alcohol. It may increase your risk of stomach bleeding.
Ask a doctor or pharmacist before using any cold, allergy, or pain medication. Many medicines available over the counter contain aspirin or other medicines similar to ketorolac. Taking certain products together can cause you to get too much of this type of medication. Check the label to see if a medicine contains aspirin, ibuprofen, ketoprofen, or naproxen.
Ketorolac side effects
Get emergency medical help if you have signs of an allergic reaction (hives, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning in your eyes, skin pain, red or purple skin rash that spreads and causes blistering and peeling).
Get emergency medical help if you have signs of a heart attack or stroke: chest pain spreading to your jaw or shoulder, sudden numbness or weakness on one side of the body, slurred speech, feeling short of breath.
Stop using ketorolac and call your doctor at once if you have:
shortness of breath (even with mild exertion);
swelling or rapid weight gain;
the first sign of any skin rash, no matter how mild;
signs of stomach bleeding--bloody or tarry stools, coughing up blood or vomit that looks like coffee grounds;
low red blood cells (anemia)--pale skin, feeling light-headed or short of breath, rapid heart rate, trouble concentrating; or
kidney problems--little or no urinating, painful or difficult urination, swelling in your feet or ankles, feeling tired or short of breath.
Common side effects may include:
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Ask your doctor before using ketorolac if you take an antidepressant such as citalopram, escitalopram, fluoxetine (Prozac), fluvoxamine, paroxetine, sertraline (Zoloft), trazodone, or vilazodone. Taking any of these medicines with an NSAID may cause you to bruise or bleed easily.
Tell your doctor about all your current medicines and any you start or stop using, especially:
heart or blood pressure medication, including a diuretic or "water pill";
steroid medicine (such as prednisone).
This list is not complete. Other drugs may interact with ketorolac, including prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible interactions are listed in this medication guide.
Remember, keep this and all other medicines out of the reach of children, never share your medicines with others, and use this medication only for the indication prescribed.
