Methohexital is a barbiturate (bar-BIT-chur-ate) that is used to cause you to fall asleep before a surgery or other medical procedure.

Methohexital may also be used for purposes not listed in this medication guide.

What should I discuss with my health care provider before receiving methohexital?

You should not be treated with methohexital if you are allergic to it, or if you have:

  • porphyria (a genetic enzyme disorder that causes symptoms affecting the skin or nervous system); or
  • an allergy to other barbiturates (butabarbital, pentobarbital, phenobarbital, secobarbital, and others).

Tell your doctor if you have ever had:

  • epilepsy or other seizure disorder;
  • asthma or chronic obstructive pulmonary disease (COPD);
  • liver or kidney disease;
  • anemia (lack of red blood cells);
  • an endocrine disorder;
  • high or low blood pressure;
  • heart disease, congestive heart failure; or
  • circulation problems.

Tell your doctor if you are pregnant.

Anesthesia may affect brain development in a young child or unborn baby (when used in the mother), leading to learning or behavior problems later in life. Long surgeries or repeated procedures pose the highest risks.

Anesthesia may still be necessary for a life-threatening condition, medical emergency, or surgery to correct a birth defect. Your doctor can give inform you about all medicines given during a surgery or procedure.

Ask a doctor if it is safe to breastfeed while using this medicine.

Methohexital should make you fall asleep very quickly.

Your breathing, blood pressure, oxygen levels, and other vital signs will be watched closely. You will also be watched closely while you are coming out of the anesthesia.

What happens if I overdose?

In a medical setting an overdose would be treated quickly.
