Barbiturates are typically used to treat anxiety, insomnia, headaches, and seizures.
Barbiturates are a type of drug that depresses the central nervous system.
The drugs are typically used to treat anxiety, insomnia, headaches, and seizures.
Your surgeon may also administer a barbiturate shortly before surgery to relieve anxiety or tension.
The first barbiturates were made in Germany during the 1860s. In 1912, the widely used barbiturate phenobarbital was introduced.
Other barbiturates include:
- Amobarbital (Amytal)
- Pentobarbital (Nembutal)
- Secobarbital (Seconal)
- Butalbital (Fiorina)
- Butabarbital (Butisol)
- Mephobarbital (Mebaral)
- Methohexital (Brevital)
- Thiamylal (Surital)
- Thiopental (Pentothal)
Today, barbiturates aren't prescribed as often as they were in the past because of the availability of newer drugs such as benzodiazepines, which don't pose as many safety concerns.
Barbiturates can be injected into muscles or veins, but they're usually taken orally.
Other Uses for Barbiturates
Barbiturates are used in high doses for performing physician-assisted suicide in states where that is legal.
They're also sometimes used along with a muscle relaxant for euthanasia or capital punishment by lethal injection.
Barbiturate Side Effects

Barbiturate 'High' and Abuse

Some people also abuse these medicines to counteract the effects of stimulant drugs such as methamphetamine or cocaine.
Barbiturate abuse is very dangerous, because an overdose can lead to coma or death.
You may experience withdrawal symptoms when you stop taking barbiturates.

Talk to your doctor if you are breastfeeding before taking a barbiturate.
