What to Expect at the Emergency Room
Take the container with you to the hospital, if possible.
The provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated. The person may receive:
- Activated charcoal
- Blood and urine tests
- Breathing support, including tube through the mouth and into the lungs breathing machine (ventilator)
- Chest x-ray
- EKG (electrocardiogram, or heart tracing)
- Fluids through a vein (by IV)
- Kidney machine (dialysis), in severe cases
- Medicine to treat symptoms

How well someone does depends on the amount of meprobamate swallowed and how quickly they receive medical treatment. The sooner medical help is given, the better the chance for recovery.
With proper care, most people recover. But, recovery may be more difficult in people with aplastic anemia. This is because their bone marrow does not produce enough red blood cells.
