I take 10 mg of Lexapro daily as a preventative for migraines. Years ago I took Wellbutrin for post-partum depression. I think I might be in need of it again. Is there a drug interaction that would prohibit this? I have a PCP who is really well qualified but I really dislike him (too old school) and I need to be armed with some facts before my next appointment with him. Please advise.
