What is the usual Lorazepam dosage?
Perhaps we should better divide that issue into two parts:
in what dosages is Lorazepam available, and
what dosages of Lorazepam are usually prescribed
Lorazepam is mainly available as 0.5mg, 1mg or 2mg tablets. Also you
can find 1mL ampoules of injectable solution containing 2mg or 4mg
Lorazepam. In some countries the medication is available as a skin
patch, an oral solution (syrop) and a sublingual tablet, too.
Lorazepam is ten times more potent than another benzodiazepine,
Diazepam. So, the less the dose (especially the initial dose) of the
medication is, the better. As a rule, Lorazepam is administered to
healthy adults in 0.5mg oral doses in the beginning of treatment,
then the dosage can be gradually increased up to 2mg at a time.
Intravenous injections should be performed slowly and patients
closely monitored for side-effects. In case of any unwanted
reactions (respiratory depression, hypotension or loss of airway
control) the injection should be immediately stopped, leaving the
rest of the ampoule's contents unused.
Lorazepam dosage should be determined on an individual basis,
depending upon the condition to be treated, the severity of
symptoms, the body weight of the patient, and any comorbidities the
patient may have.
In pediatric and elderly patients Lorazepam dosage should be
normally less than in adults and individualized even more carefully.
