Last updated
For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.
Summary
Ketorolac inhibits platelet function and can injure the gastrointestinal mucosa, and systemic absorption from the nasal spray is meaningful. With heparin the risk of serious bleeding is increased, and ketorolac labeling warns against use with anticoagulants.
What this interaction means in plain words
Heparin and Ketorolac intranasal can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Why it happens
Additive hemostatic impairment: NSAID-mediated reversible platelet COX-1 inhibition plus heparin anticoagulation, with added GI mucosal injury.
What to do
Avoid ketorolac in patients on therapeutic heparin; choose a non-NSAID analgesic such as acetaminophen. If unavoidable, monitor closely for bleeding and check hemoglobin.
What to ask your pharmacist
- Does the benefit of taking both outweigh the risk in my case?
