US Brand Names
Ketorolac is used to relieve moderately severe pain, usually pain that occurs after an operation or other painful procedure. It belongs to the group of medicines called nonsteroidal anti-inflammatory drugs (NSAIDs). Ketorolac is not a narcotic and is not habit-forming. It will not cause physical or mental dependence, as narcotics can. However, ketorolac is sometimes used together with a narcotic to provide better pain relief than either medicine used alone.
Ketorolac has side effects that can be very dangerous. The risk of having a serious side effect increases with the dose of ketorolac and with the length of treatment. Therefore, ketorolac should not be used for more than 5 days. Before using this medicine, you should discuss with your doctor the good that this medicine can do as well as the risks of using it.
Ketorolac is available only with your doctor's prescription.
Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although these uses are not included in product labeling, ketorolac is used in certain patients with the following medical conditions:
- Pain after surgery in children

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 this medicine, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine 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.
Studies on this medicine have been done only in adult patients, and there is no specific information comparing use of ketorolac in children up to 16 years of age with use in other age groups.
Stomach or intestinal problems, swelling of the face, feet, or lower legs, or sudden decrease in the amount of urine may be especially likely to occur in elderly patients, who are usually more sensitive than younger adults to the effects of ketorolac. Also, elderly people are more likely than younger adults to get very sick if the medicine causes stomach problems. Studies in older adults have shown that ketorolac stays in the body longer than it does in younger people. Your doctor will consider this when deciding on how much ketorolac should be given for each dose and how often it should be given.
