Overdose
Symptoms
- Overdose can lead to decreased
heart function or Cardiac Arrest. Symptoms include staggered walking,
rapid eye movements, unusual body movements, and
drowsiness. Blood tests can determine the level of the
overdose. Overdose can occur at regularly prescribed
doses if the dose is only a little too high, because it will
build up in the blood over time.
