Bupropion and RLS
A small randomized trial found that bupropion did not exacerbate RLS and may have improved symptoms short term. Current AASM guidance nevertheless recommends against using bupropion as a treatment for RLS itself — a different question from choosing an antidepressant in someone who also has RLS.
