Summary

Levomilnacipran, an SNRI, reduces platelet serotonin content and can impair platelet aggregation, while oxaprozin inhibits platelet function and damages the gastric mucosa. Combining them raises the risk of gastrointestinal and other bleeding, particularly in older patients or those on anticoagulants.

What this interaction means in plain words

Levomilnacipran and Oxaprozin 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.

Levomilnacipran belongs to Central Nervous System; Oxaprozin belongs to Musculoskeletal.

Evidence level: Moderate

Why it happens

Additive impairment of platelet aggregation (serotonin depletion plus COX inhibition) with NSAID-related mucosal injury.

What to do

Monitor for signs of gastrointestinal bleeding and consider gastroprotection with a proton pump inhibitor in higher-risk patients. Use the lowest effective NSAID dose for the shortest time, or choose acetaminophen if appropriate.
