Ketorolac Medication for Pain

If you have moderate to severe pain, a healthcare provider may prescribe ketorolac tromethamine (Toradol®). As a medication for pain, ketorolac is approved to provide short-term relief caused by things such as a medical procedure, kidney stones, back pain, or cancer pain.
It is believed that ketorolac works to reduce pain by blocking the effects of prostaglandins. In clinical studies, ketorolac was as effective as lower doses of narcotics at treating pain. When it was combined with narcotic pain medicines (such as morphine), it decreased the amount of narcotics needed. Also, pain relief was significantly better in those receiving ketorolac and morphine compared to those receiving morphine alone.
After the medication is taken, pain relief usually begins in about 30 minutes. The maximum effect of ketorolac occurs within two to three hours and lasts, on average, for four to six hours. Possible side effects include nausea, drowsiness, and headaches.
Ketorolac is available in the form of an injection or as tablets. Ketorolac injections are available in several strengths, including 15 mg per mL vial, 30 mg per mL vial, and 60 mg per 2-mL vial. The tablets are available in one strength -- ketorolac 10 mg.
