Lexapro and Wellbutrin Combo: Why Doctors Call It the 'Well-Pro' Protocol
The most common reason for adding bupropion to an established escitalopram prescription is sexual dysfunction mitigation. Serotonin 5-HT2A and 5-HT2C receptor stimulation suppresses the spinal reflexes that govern genital arousal and orgasm. Bupropion bypasses this blockage by stimulating dopamine receptors, which compete directly against serotonergic dampening in sexual pleasure centers.
Clinical studies show that 150 mg to 300 mg of adjunctive bupropion often restores orgasmic sensation and erectile strength within three to six weeks, without requiring any reduction in escitalopram dosage.
Weight gain counteraction represents a second clinical target. While escitalopram can stimulate appetite and disrupt insulin sensitivity over extended treatments, bupropion stimulates pro-opiomelanocortin (POMC) neurons in the hypothalamus. These neurons signal fullness and suppress cravings. When bupropion is added, patients regularly stabilize their baseline weight or drop the pounds accumulated during SSRI monotherapy.
