Alphalok XR Prazosin Hydrochloride Propranolol Hydrochloride
ModeratePrazosin (Alphapress XR) and propranolol have been used together, and no harmful interaction has been seen in clinical experience so far. Propranolol is one of the heart rhythm medicines the leaflet lists as having been given alongside it without problems. That is only what has been observed to date. Take both medicines exactly as your doctor prescribes them, and tell your doctor about any other medicines you use.
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.
