Generic Name: ketorolac (kee-toe-ROLE-ak)
Nonsteroidal anti-inflammatory drugs (NSAIDS) cause an increased risk of serious cardiovascular thrombotic events, including myocardial infarction and stroke, which can be fatal. This risk may occur early in treatment and may increase with duration of use. Ketorolac tromethamine is contraindicated in the setting of coronary artery bypass graft (CABG) surgery. NSAIDS cause an increased risk of serious gastrointestinal (GI) adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. These events can occur at any time during use and without warning symptoms. Elderly patients and patients with a prior history of peptic ulcer disease and/or GI bleeding are at greater risk for serious GI events .

Uses for ketorolac
Ketorolac nasal spray is used to relieve moderate to moderately severe pain (eg, pain that occurs after an operation or other painful procedure) for a short time only. It is a nonsteroidal anti-inflammatory drug (NSAID) which lessens pain and inflammation.
Ketorolac has side effects that can be very dangerous. The risk of having a serious side effect increases with the amount and the length of time it is used. Ketorolac should not be used for more than 5 days in a row. Before using ketorolac, you should discuss with your doctor the benefits as well as the risks of using it.
Ketorolac is available only with your doctor's prescription.
Before using ketorolac
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For ketorolac, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to ketorolac or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of ketorolac nasal spray in the pediatric population. Use is not recommended in children younger than 2 years of age. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of ketorolac nasal spray in the elderly. However, because of ketorolac's toxicity, it should be used with caution in the elderly, after less toxic alternatives have been considered or found ineffective. Recommended doses should not be exceeded, and the patient should be carefully monitored during treatment. In addition, elderly patients are more likely to have age-related heart, kidney, liver, or stomach or bowel problems, which may require caution and an adjustment in the dose for patients receiving ketorolac nasal spray.
Studies in women breastfeeding have demonstrated harmful infant effects. An alternative to this medication should be prescribed or you should stop breastfeeding while using ketorolac.

Proper use of ketorolac
Use ketorolac only as directed by your doctor. Do not use more of it, do not use it more often, and do not use it for a longer time than your doctor ordered. Do not use it for more than 5 days in a row. The total number of days also includes any doses of ketorolac that may be given in a hospital or clinic setting. Using too much of ketorolac increases the chance of side effects, especially in elderly patients.
Ketorolac should come with a Medication Guide and patient instructions. Read and follow the instructions carefully. Ask your doctor if you have any questions.
Ketorolac is only used in the nose. Do not breathe in (inhale) ketorolac while spraying. Do not get any of it into your eyes. If it does get into the eyes, rinse them with water or saline right away and call your doctor.
Drink extra fluids while you are using ketorolac. This will keep your kidneys working well and help prevent kidney problems.
- If you are using the nasal spray for the first time, you will need to prime the spray. To do this, pump the bottle 5 times until some of the medicine sprays out. Now it is ready to use.
- Gently blow your nose to clear the nostrils.
- Sit or stand up straight and tilt your head slightly forward.
- Insert the tip of the bottle into your right nostril. Point the bottle away from the center of your nose.
- Hold your breath and spray once into your right nostril. Slowly breathe in through your mouth. You may want to pinch your nose, to allow the medicine to be absorbed through the skin inside your nose.
- If your dose is 2 sprays, spray once into your left nostril the same way.
- After using the spray, wipe the tip of the bottle with a clean tissue and put the clear plastic cover back on.
- Do not use the bottle for more than 24 hours after your first dose. Throw the bottle away after 24 hours even if it still has liquid inside it.
The dose of ketorolac will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of ketorolac. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
- For nasal dosage form (spray):
- For pain:
- Adults weighing 50 kilograms (kg) or more—31.5 milligrams (mg) or 1 spray in each nostril every 6 to 8 hours. Your doctor may adjust your dose if needed. However, the dose is not more than 126 mg (a total of 8 sprays) per day.
- Older adults and adults weighing less than 50 kg—15.75 mg or 1 spray in only one nostril every 6 to 8 hours. However, the dose is usually not more than 63 mg (a total of 4 sprays) per day.
- Children—Use and dose must be determined by your doctor.
- For pain:
If you miss a dose of ketorolac, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.
Keep out of the reach of children.
Do not keep outdated medicine or medicine no longer needed.
Ask your healthcare professional how you should dispose of any medicine you do not use.
Keep the unopened bottle in the refrigerator. Protect it from light and freezing. Once opened, store the bottle at room temperature, away from heat and direct sunlight. Throw away any unused medicine 24 hours after you opened the bottle and used your first dose.
Precautions while using ketorolac
It is very important that your doctor check your progress while you are using ketorolac. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to use it.
Do not use any other form of ketorolac (eg, injection or tablets) or other NSAIDs, unless your doctor says it is okay. Some examples of NSAIDs are aspirin, diclofenac, ibuprofen, or naproxen (Advil®, Aleve®, Celebrex®, Ecotrin®, Motrin®, or Voltaren®). Also, you should not use ketorolac together with pentoxifylline (Trental®) or probenecid (Benemid®).
Ketorolac may cause bleeding in your stomach or bowels. This problem can happen without warning signs. This is more likely if you have had a stomach ulcer in the past, you smoke or drink alcohol regularly, are over 60 years of age, are in poor health, or are using certain other medicines (such as steroids or a blood thinner). Call your doctor right away if you have bloody or black, tarry stools, severe stomach pain or heartburn, or vomiting of blood or material that looks like coffee grounds.
Ketorolac may increase your risk of having blood clots, heart attack, or stroke. This is more likely in people who already have heart disease. Call your doctor right away if you have chest pain or discomfort, an irregular or fast heartbeat, severe indigestion or heartburn, nausea, sweating, or troubled breathing with exertion.
Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, unusual tiredness or weakness, or yellow eyes or skin. These could be symptoms of a serious liver problem.
Some possible warning signs of serious side effects that can occur during treatment with ketorolac may include black, tarry stools, decreased urination, severe stomach pain, skin rash, swelling of the face, fingers, feet, or lower legs, unusual bleeding or bruising, unusual weight gain, vomiting of blood or material that looks like coffee grounds, or yellow skin or eyes. Also, signs of serious heart problems could occur, such as chest pain, fast or irregular heartbeat, tightness in the chest, unusual flushing or warmth of the skin, weakness, or slurring of speech. Check with your doctor right away if you notice any of these warning signs.
Ketorolac may cause a serious type of allergic reaction called anaphylaxis. Although this is rare, it may occur more often in patients who are allergic to aspirin or non-steroidal anti-inflammatory drugs (NSAIDs). Anaphylaxis can be life-threatening and requires immediate medical attention. The most serious signs of this reaction are very fast or irregular breathing, gasping for breath, or fainting. Other signs may include changes in color of the skin of the face, very fast but irregular heartbeat or pulse, hive-like swellings on the skin, and puffiness or swelling of the eyelids or around the eyes. If these effects occur, get emergency help at once.
Serious skin reactions can occur during treatment with ketorolac. Check with your doctor right away if you have blistering, peeling, or loosening of the skin, red skin lesions, severe acne or skin rash, sores or ulcers on the skin, or fever or chills while you are using ketorolac.
It is important to tell your doctor if you are pregnant or planning to become pregnant before using ketorolac. Using ketorolac while you are pregnant can harm your unborn baby. Do not use ketorolac during the latter part of a pregnancy unless your doctor tells you to.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
