Beta blockers are a type of drug used to treat high blood pressure.

Beta blocker overdose occurs when someone accidentally or intentionally takes more than the normal or recommended amount of this medication.

The specific ingredient in such drugs varies among manufacturers. The main ingredient is a beta-adrenergic blocking substance. It blocks the effects of a hormone called epinephrine on the body. Epinephrine is also called adrenaline.
