Had no libido when on 10mg of lexapro (escitalopram). doc recently upped dosage to 20mg due to brain fog rearing its ugly head again. libido back. make any sense?

Yes: One symptoms of depression is low sex drive. Your depression returned. Your antidepressant was increased and then the depression cleared and your libido returned. Very common scenario in psychiatry.

Yes, makes sense: Yes, feeling better when your Lexapro (escitalopram) dose was raised makes sense -- your symptoms of brain fog and lack of libido could have been from depression, which Lexapro (escitalopram) helps to treat. This goes to show that when prescribed in the right way for the right people, Lexapro (escitalopram) can be helpful -- and isn't all bad! glad you're feeling better. You can carry this even further with psychotherapy. Be well.
