Ketorolac is a potent NSAID with significant antiplatelet and gastrointestinal bleeding risk, and venlafaxine further impairs platelet function. The combination raises the chance of serious bleeding.
What this interaction means in plain words
Ketorolac intranasal and Venlafaxine 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

What to do
Limit ketorolac to the shortest course allowed and monitor for bleeding. Consider an alternative analgesic or gastroprotection in at-risk patients.
