Summary
Ketorolac, like other NSAIDs, can blunt the blood pressure lowering effect of labetalol through prostaglandin inhibition and fluid retention. Prolonged use may also affect renal function, which is a concern in hypertensive patients.
What this interaction means in plain words
Ketorolac intranasal and Labetalol can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Inhibition of prostaglandin synthesis causes sodium and water retention and reduced vasodilation, opposing the effect of labetalol.
What to do
Monitor blood pressure if ketorolac is used for more than a few days with labetalol and limit the duration of therapy. Consider a non-NSAID analgesic if blood pressure rises.
What to ask your pharmacist
