well ask your doctor because usually they would know best. but im on vistaril i take it before bed to make me sleep and in the daytime as needed for anxiety. vistaril is sometimes also used as an allergy medication so i would imagine it wouldnt harm your breathing. i dont have asthma though.
is there an antidepressant for sleep and anxiety that doesn't cause difficulty in breathing? i have severe asthma. . and my lung function has dropped considerably.
