Safety information
Before taking this medicine
Do not take Dibenzyline if you are allergic to phenoxybenzamine or any of its ingredients, or if you have a condition in which a fall in blood pressure would be undesirable.
Interactions
Tell your doctor if you use epinephrine or other medicines that stimulate both alpha- and beta-adrenergic receptors. Combining these with phenoxybenzamine may cause an unusually large drop in blood pressure and a rapid heartbeat. Also mention levarterenol or reserpine. Phenoxybenzamine can block the rise in body temperature caused by levarterenol and the fall in body temperature caused by reserpine.
