Summary

Venlafaxine impairs platelet serotonin uptake and, with an NSAID, increases the risk of gastrointestinal and other bleeding. The effect is clinically important in older patients and those with ulcer history.

What this interaction means in plain words

Ketoprofen and Venlafaxine 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.

Ketoprofen belongs to Musculoskeletal; Venlafaxine belongs to Central Nervous System.

Evidence level: Moderate

Why it happens

Serotonin reuptake inhibition depletes platelet serotonin, adding to NSAID COX-1 platelet inhibition and gastric mucosal damage.

What to do

Monitor for bleeding signs and consider gastroprotection with a proton pump inhibitor in at-risk patients. Use the lowest effective NSAID dose for the shortest duration.
