Amobarbital injection

What does amobarbital injection do?

AMOBARBITAL (Amytal®) is a barbiturate that slows down activity of the brain and nervous system. Amobarbital has both sedative and hypnotic properties which means it will help you to relax and sleep. Amobarbital can help produce relaxation and drowsiness before surgery. Amobarbital also can help reduce or control seizures (convulsions). It is not for the long-term control or prevention of seizures. Federal law prohibits the transfer of amobarbital to any person other than the patient for whom it was prescribed. Do not share your medicine with anyone else. Generic amobarbital injections are available.

What should my health care professional know before I receive amobarbital?

They need to know if you have any of these conditions:

  • an alcohol or drug abuse problem

  • breathing difficulties or lung disease

  • attempted suicide

  • heart disease

  • liver disease

  • mental depression or mental problems

  • porphyria

  • an unusual or allergic reaction to amobarbital, other barbiturates, medicines, foods, dyes, or preservatives

  • pregnant or trying to get pregnant

  • breast-feeding

How should I use this medicine?

Tell your prescriber or health care professional about all other medicines you are taking, including non-prescription medicines, nutritional supplements, or herbal products.

These may affect the way your medicine works. Check with your health care professional before stopping or starting any of your medicines.

What should I watch for while taking amobarbital?

Your condition will be monitored closely if you are receiving amobarbital for an immediate need. If you do receive amobarbital regularly, visit your prescriber or health care professional for regular checks on your progress.

After receiving amobarbital you may get a residual hangover effect that leaves you drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how amobarbital affects you. To reduce dizzy or fainting spells, do not sit or stand up quickly, especially if you are an older patient. Alcohol can increase possible unpleasant effects. Avoid alcoholic drinks.

Amobarbital can stop birth control pills (oral contraceptives) working properly. Use another method of birth control while you are using amobarbital.

If you are going to have surgery, tell your prescriber or health care professional that you are receiving amobarbital.
