Is anyone taking lexapro for PTSD and or anxiety/depression? Is it working, when did it start to work and at what dosage? I am currently on a low dosage of lexapro (med sensitive) 2.5 mg to work up to 5 mg in a couple of weeks. I am also currently on amitriptyline 12.5 mg, guanfacine 1 mg at night (for night terrors) and buspar 10 mg two times a day along with the lexapro. Started lexapro because the amitrip is too low a dose for depression. Would like to eventually stop the buspar if the lexapro works. Appreciate the feed back, thank you!
