Description
Butabarbital is used to treat insomnia (trouble sleeping). It is also used before a surgical procedure to make a person sleep (be unconscious).
Butabarbital belongs to the group of medicines called barbiturates. They act in the central nervous system (CNS) to slow down the nervous system. When used to treat insomnia, butabarbital will help you get to sleep faster and sleep throughout the night. In most cases, sleep medicines should only be used for short periods of time, such as 1 or 2 days, and for no longer than 1 or 2 weeks.
This medicine is available only with your doctor's prescription.
This product is available in the following dosage forms:

Before Using

Do not drive or do anything else that could be dangerous until you know how this medicine affects you.
If you develop any unusual and strange thoughts or behavior while you are using butabarbital, be sure to discuss it with your doctor. Some changes that have occurred in people using this medicine are like those seen in people who drink alcohol and then act in a manner that is not normal.

If you think you or someone else may have taken an overdose of this medicine, get emergency help at once. Taking an overdose of butabarbital or taking alcohol or other CNS depressants with butabarbital may lead to serious breathing problems and unconsciousness.
