Generic Name: midazolam (Injection route)

MID-ay-zoe-lam

Oral routeSyrup
  • Midazolam hydrochloride syrup has been associated with respiratory depression and respiratory arrest, especially when used for sedation in noncritical care settings. Midazolam hydrochloride syrup has been associated with reports of respiratory depression, airway obstruction, desaturation, hypoxia, and apnea, most often when used concomitantly with other central nervous system depressants (eg, opioids). Midazolam hydrochloride syrup should be used only in hospital or ambulatory care settings, including physicians’ and dentists’ offices, that can provide for continuous monitoring of respiratory and cardiac function. Immediate availability of resuscitative drugs and age- and size-appropriate equipment for ventilation and intubation, and personnel trained in their use and skilled in airway management should be assured. For deeply sedated patients, a dedicated individual, other than the practitioner performing the procedure, should monitor the patient throughout the procedure .

Injection routeSolution
  • Adult and Pediatric:
    • Intravenous midazolam has been associated with respiratory depression and respiratory arrest, especially when used for sedation in noncritical care settings. In some cases, where this was not recognized promptly and treated effectively, death or hypoxic encephalopathy has resulted. Intravenous midazolam hydrochloride should be used only in hospital or ambulatory care settings, including physicians’ and dental offices, that provide for continuous monitoring of respiratory and cardiac function, ie, pulse oximetry. Immediate availability of resuscitative drugs and age- and size-appropriate equipment for bag/valve/mask ventilation and intubation, and personnel trained in their use and skilled in airway management should be assured. For deeply sedated pediatric patients, a dedicated individual, other than the practitioner performing the procedure, should monitor the patient throughout the procedures.
    • The initial intravenous dose for sedation in adult patients may be as little as 1 mg, but should not exceed 2.5 mg in a normal healthy adult. Lower doses are necessary for older (over 60 years) or debilitated patients and in patients receiving concomitant narcotics or other central nervous system (CNS) depressants. The initial dose and all subsequent doses should always be titrated slowly; administer over at least 2 minutes and allow an additional 2 or more minutes to fully evaluate the sedative effect. The use of the 1 mg/mL formulation or dilution of the 1 mg/mL or 5 mg/mL formulation is recommended to facilitate slower injection. Doses of sedative medications in pediatric patients must be calculated on a mg/kg basis, and initial doses and all subsequent doses should always be titrated slowly. The initial pediatric dose of midazolam for sedation/anxiolysis/amnesia is age, procedure, and route dependent.
  • Neonates:
    • Midazolam hydrochloride should not be administered by rapid injection in the neonatal population. Severe hypotension and seizures have been reported following rapid IV administration, particularly with concomitant use of fentanyl .

Uses For Versed

Midazolam is used to produce sleepiness or drowsiness and to relieve anxiety before surgery or certain procedures. Midazolam is also given to produce amnesia (loss of memory) so that the patient will not remember any discomfort or undesirable effects that may occur after a surgery or procedure . It is also used to produce loss of consciousness before and during surgery. Midazolam is sometimes used in patients in hospital intensive care units to cause unconsciousness. This may allow the patient to withstand the stress of being in the intensive care unit and help the patient cooperate when a machine must be used to assist with breathing.

Midazolam is given only by or under the immediate supervision of a doctor trained to use this medicine. If you will be receiving midazolam during surgery, your doctor or anesthesiologist will give you the medicine and closely follow your progress.

Precautions While Using Versed

For patients going home within 24 hours after receiving midazolam:

Therefore, do not drive, use machines, or do anything else that could be dangerous if you are not alert until the effects of the medicine have disappeared or until the day after you receive midazolam, whichever period of time is longer.
