Serotonin-norepinephrine reuptake inhibitor (SNRI)
Venlafaxine dosage guide: how much to take and when
Choosing the right dose of Venlafaxine (Venlafaxine) is the most important practical decision after starting therapy. Venlafaxine is supplied as capsule in 37.5mg, 75mg, 150mg, and the right dose for a given person depends on the indication, age, comorbidities and tolerance to the active ingredient Venlafaxine.
Starting dose and titration
According to the prescribing information, most adults begin Venlafaxine at the lowest available strength of 37.5mg, 75mg, 150mg 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. Venlafaxine inhibits the reuptake of both serotonin and norepinephrine at the synapse, with a dose-dependent profile: at low doses (≤75mg) it acts mainly on serotonin like an SSRI, while at higher dos… 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.
