Phenoxybenzamine - Warnings and Precautions

The following warnings and precautions are taken directly from the US FDA-approved drug label for Phenoxybenzamine. This is the same information dispensing pharmacists read.

WARNING Phenoxybenzamine hydrochloride-induced alpha -adrenergic blockade leaves beta -adrenergic receptors unopposed.

Compounds that stimulate both types of receptors may, therefore, produce an exaggerated hypotensive response and tachycardia.
