An endocrinologist: B"sd It is essential to define the nature and source of the excess "adrenaline", which usually refers to normetanephrine (NE) and less commonly but much more dangerous epinephrine (E). Metoprolol is a selective beta blocker which can counter the effects of excess NE. However, E is both beta and alpha. In conditions of E excess metoprolol can result in paradoxical severe hypertension emergency
