Research Context

Research context compiled from published sources

How does Venlafaxine work?

Inhibits reuptake of serotonin and noradrenaline, increasing their availability in the synaptic cleft. Serotonin plays a role in central thermoregulation via 5-HT2A receptors in the hypothalamus. Increasing serotonergic activity may help stabilise the thermoneutral zone, reducing vasomotor symptoms independently of oestrogen.

Research Depth

Well Studied

Extensive human research over many years, including randomized controlled trials.

Long-Term Evidence

Well Characterized

Decades of long-term safety data available from human use.
