DOSINA

Amobarbital

Depressant

A sedative and hypnotic barbiturate first discovered in 1923. Formerly widely used recreationally and medically, barbiturates have declined in popularity with the appearance of benzodiazepines and other drugs with less serious consequences in overdose.

Harm reduction

  • Depressants are the class where mixing kills most often: alcohol, benzodiazepines, GHB/GBL and opioids all suppress breathing when combined.
  • Never use alone. If you use alone, set up a check-in call with someone who will call emergency services if you do not answer.
  • Measure liquid doses with a syringe. Bottle caps, teaspoons and 'glugs' are how people take ten times the intended dose.
  • Sedation can be delayed. Do not re-dose before you can feel the previous dose fully.
  • Do not stop daily benzodiazepine or alcohol use abruptly - withdrawal can cause seizures and is potentially fatal. Taper with medical help.
  • Signs that someone needs emergency help: breathing slower than one breath every 4-5 seconds, blue lips, snoring that will not stop, unrousable, vomiting while unconscious.
