Switch medication from bupropion to venlafaxine.
- Gradually reduce dosage of bupropion to a maximum of 150 mg/day.
- When a dosage of 150 mg/day is reached, stop administration.
- Day 1-7: a wash-out period of at least one week is necessary.
- Day 8: start venlafaxine in a normal dosage of 37,5 mg or 75 mg (slow release) /day.
- By considering a wash-out period of one week (5 times the elimination time of bupropion and its metabolites) it is assured that all bupropion has left the body and no drug interactions occur.
- Bupropion slows the metabolism of venlafaxine by CYP2D6.
