Mechanism & Pharmacology

Curious about how Venlafaxine works? It’s a serotonin-norepinephrine reuptake inhibitor (SNRI) that helps balance neurotransmitters in the brain, primarily serotonin and norepinephrine. By inhibiting their reabsorption, Venlafaxine leads to improved mood and reduced anxiety.

Health Canada's approved monographs detail its pharmacological action, highlighting how it impacts the central nervous system. This mechanism promotes psychological well-being, making it a popular choice among prescribers for conditions like major depressive disorder and generalized anxiety disorder.

Indications & Off-Label Uses in Canada

Health Canada officially approves Venlafaxine for several conditions, notably major depressive disorder, generalized anxiety disorder, social anxiety disorder, and panic disorder. These indications ground its therapeutic use in clinical practice.

Physicians in Canada often prescribe Venlafaxine off-label, which includes notable practices for treating neuropathic pain and migraine headaches. This versatility makes it a valuable asset in managing various mental health and pain conditions.
