Diazapam Diazepam Prazosin Hydrochloride
ModeratePrazosin (Alphapress XR) has been given together with diazepam in clinical experience so far, and no harmful interaction has been reported. The leaflet lists diazepam among the sedatives and tranquilizers that have been used alongside it without problems. Even so, take the two together only as your doctor has advised.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
