Written by Stephanie Nera, RPh, PharmD · Pharmacology

Updated Jul 07, 2021

Dormicum is the brand name of the drug midazolam. Midazolam is a benzodiazepine which has sedative-hypnotic properties. In the Philippines, midazolam is a dangerous drug under schedule IV. This means only physicians with a S-2 license can prescribe this drug.



What is Dormicum used for?

Dormicum is used to relieve anxiety and cause sleepiness among patients due for surgery. It also causes loss of consciousness and short-term memory before and during surgery. Some uses include the treatment of patients in intensive care units, dental extraction, and other minor and major operations. The drug allows individuals to withstand stress and cooperate during hospital procedures.

How should I take Dormicum?

The duration of treatment should be as short as possible. Generally, the duration of treatment varies from a few days to a maximum of 2 weeks. The tapering-off process should be tailored to the individual. Treatment with Dormicum should not be terminated abruptly.

Dormicum tablets should be taken immediately before going to sleep and swallowed whole with fluid.

Dormicum can be taken at any time of the day, provided the patient is subsequently assured of at least 7 to 8 hours of undisturbed sleep.

How do I store Dormicum?

Dormicum is best stored at room temperature away from direct light and moisture. To prevent drug damage, you should not store Dormicum in the bathroom or the freezer. There may be different brands of midazolam that may have different storage needs. It is important to always check the product package for instructions on storage, or ask your pharmacist.
