  • Medicine called an antidote to reverse the effects of the poison and treat symptoms, such as sodium bicarbonate or lidocaine

People who swallow too much of this medicine are almost always admitted to the hospital.

How well someone does depends on how much of the medicine was swallowed and how quickly treatment is given. The faster a person gets medical help, the better the chance of recovery. Complications such as heart rhythm disturbances, pneumonia, muscle damage from lying on a hard surface for a long period of time, or brain damage from lack of oxygen may result in permanent disability. Death can occur.
