Ativan dosage guide: how much to take and when
Choosing the right dose of Ativan (Lorazepam) is the most important practical decision after starting therapy. Ativan is supplied as tablet, oral concentrate, injection in 0.5mg, 1mg, 2mg, and the right dose for a given person depends on the indication, age, comorbidities and tolerance to the active ingredient Lorazepam.
Starting dose and titration
According to the prescribing information, most adults begin Ativan at the lowest available strength of 0.5mg, 1mg, 2mg and titrate up only if symptom control is insufficient and tolerability is good. Higher doses are reserved for selected cases. Older adults, people with renal or hepatic impairment, and those taking interacting medications should usually start at the lowest dose.
When to adjust
Dose adjustment is guided by symptom response and side effect burden, not by arbitrary schedules. Lorazepam binds the benzodiazepine site of the GABA-A receptor and allosterically enhances inhibitory chloride conductance. If side effects are limiting at a given dose, going down a step is usually preferred over stopping abruptly. If the response is incomplete after several weeks, a higher dose can be tried under medical supervision.
