How Midazolam Works

  • Mechanism of Action:
    • Midazolam is a benzodiazepine that acts on the central nervous system (CNS) by enhancing the effects of gamma-aminobutyric acid (GABA), a natural chemical in the brain that produces a calming effect.

How to Use

  • Administration:
    • Prepared and administered by a healthcare professional, usually given as a single dose before surgery or anesthesia.
  • Dosage:
    • Determined by a medical condition, response to treatment, weight, and other medications taken.

Withdrawal and Dependence

  • Withdrawal Symptoms:
    • Sudden cessation can lead to shaking, sweating, vomiting, cramps, and seizures.
    • Gradual dosage reduction is recommended to avoid withdrawal.
  • Addiction Potential:
    • Risk of addiction, especially in those with a history of substance use disorders.
    • Do not exceed the prescribed dose or duration of use.
