I have been on Lexapro 20 mg/day to treat anxietal depression for about 2 years. While it seemed to work quite well for this time, over the past few months I have noticed an emerging pattern of mood swings, easily frustrated by insignificant issues and, at times, the observation that I would not be missed if I was gone. I do not have suicidal thoughts or planning. I had been attributing this to not being able to relax at anything and the stress of daily life.
Is it possible for Lexapro to lose it's effectiveness? I see my doctor this Friday for a follow up and was thinking of asking for him to add Abilify but I really don't want to keep adding meds to this. Any thoughts would be helpful.
