You should not consume alcohol when using ketorolac. Alcohol might increase your chances of experiencing gastrointestinal bleeding caused by ketorolac. If you develop signs of bleeding in your stomach or intestines, contact your doctor right once. Avoid drinking alcohol altogether if you experience nausea and vomiting while taking this medication. Ketorolac is used to reduce pain and inflammation from an injury or surgery. It is usually taken once a day at bedtime. Do not take it more often than advised by your doctor. Follow instructions on your prescription label carefully for accurate administration of ketorolac. Your doctor may have suggested this medication for you because he or she has found that chronic use of non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and naproxen can lead to stomach ulcers. Although ketorolac does not cause stomach problems like some NSAIDs, it has been shown to cause serious eye problems. Therefore, if you are at risk for developing diabetes or heart disease, your doctor may have recommended ketorolac instead of an NSAID such as ibuprofen or naproxen. Take the drug only when needed according to instructions above. If you forget a dose, take it as soon as you remember, then go back to sleep. Only take the medicine for the length of time recommended by your doctor.
