Summary
Duloxetine impairs platelet serotonin uptake and raises bleeding risk. Green tea has mild antiplatelet properties in theory, so bleeding risk could be slightly greater, although clinical evidence is scant.
What this interaction means in plain words
Duloxetine and Green tea have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Duloxetine belongs to Central Nervous System; Green tea belongs to Gastrointestinal Tract.
Why it happens
Additive effects on platelet function: SNRI depletion of platelet serotonin and possible antiplatelet activity of green tea catechins.
What to do
No routine action is needed for usual tea intake. Watch for bruising or bleeding if the patient also takes anticoagulants or NSAIDs.
