My husband is has taken lexapro for 15 days at 10mg per day and feels more anxious and depressed than before. He also takes quetiapine fumarate at night to sleep. Are they ok together? Do either of these build up and liver and then cause a stupor effect as that happened two days ago, and it took me hours to get his breathing from 85 to 95 on the pulse finger indicator. I called his doc and he said increase the lexapro to 20mg. Does this sound ok?
