My husband quit taking escitalopram. I found out after his behavior changed dramatically. Our lives have been dramatically changed. Yesterday, he became so upset, he was shaking and out of control. I gave him space by leaving for a few hours to give him time to settle down. When I arrived home, he told me that he had been thinking about killing a certain person, but, thank God, he didn t. When he resumes taking his meds, how soon will his out of control, irrational behavior change?
