Frequently asked questions

Why is ketorolac only used for a few days?

It is a strong NSAID with a high risk of stomach bleeding and kidney problems, so courses are kept very short.

Is ketorolac an opioid?

No — it is an NSAID, so it does not cause addiction, but it has its own serious risks.

Can I take ibuprofen with ketorolac?

No — combining NSAIDs increases bleeding and kidney risks.
