Reversal of Sedation - I would like to know if there is a drug that will help bring someone out from

If the person is very much unconscious you should take them to the doctor. If they are able to be woken up but fall asleep again, then just let them sleep it through.

In terms a medicine used for reversing sedation, yes Flumazenil reverses the effects of certain types of sedatives from the benzodiazepine group of drugs. This includes Valium, Xanax, Tranxene, Librium, ProSom, Dalmane, Ativan, Restoril, Halcion, and others.

Flumazenil is used to reverse the sedative effects of a benzodiazepine when used during surgery or other medical procedure. It is also used to treat benzodiazepine overdose.

This must be administered with caution as it has its own risks.
