Dosing of Medicine differ in Adult & Pediatrics ↓


Adult Dose

S.No Ailment   Route   Dose Min   Dose Max   Unit   Dosage Form   Frequency   Additional Info
1 Reversal of benzodiazepine-induced sedation IV 200 micrograms Injection This is followed at intervals of 60 seconds by further doses of 100 to 200 micrograms if required, to a maximum total dose of 1 mg or occasionally 2 mg (usual range, 0.3 to 1 mg); each dose should be given over 15 seconds, and further doses should only be given if an adequate response has not occurred 45 seconds after completion of the injection. If drowsiness recurs an intravenous infusion may be used, at a rate of 100 to 400 micrograms/hour.
2 Management of benzodiazepine overdose IV 200 micrograms Injection Given over 30 seconds. A further dose of 300 micrograms can be given after another 30 seconds and can be followed by doses of 500 micrograms at one-minute intervals if required, to a total dose of 3 mg or occasionally 5 mg. If a dose of up to 5 mg produces no response then further doses are unlikely to be effective. If symptoms of intoxication recur, repeated doses may be given at 20-minute intervals; not more than 1 mg, in boluses of 500 micrograms and above, should be given at any one time and not more than 3 mg in one hour. If signs of overstimulation occur during the use of flumazenil, then diazepam or midazolam may be given by slow intravenous injection.
