I doubt it. Escitalopram is the
generic of Lexapro. I asked my psychiatrist if the
generic works any differently, as every now and then you hear of generics not working quite as well. She said there is virtually no difference in the drugs, except for the fact that one is a brand name and one is a generic. However, I recently went through the same thing as you. I'd been on Lexapro for eight years and did so well on it, and out of the blue it stopped working.
