Lexapro (escitalopram) and Wellbutrin (bupropion) are sometimes prescribed together intentionally to treat depression that does not respond adequately to either drug alone. This combination is generally well-tolerated, though bupropion can increase escitalopram blood levels and there is a slightly elevated seizure risk.
How This Interaction Works (Mechanism)
Bupropion inhibits CYP2D6, one of the enzymes involved in escitalopram metabolism. This can increase escitalopram plasma concentrations by approximately 30 to 40 percent. Bupropion acts primarily on norepinephrine and dopamine reuptake, while escitalopram targets serotonin, so their therapeutic mechanisms are complementary rather than redundant. The seizure threshold may be slightly lowered by the combination.

Report any new or worsening side effects, including tremor, restlessness, or seizures. Do not start or stop either medication without consulting your doctor. Avoid alcohol, which can further lower the seizure threshold.
