Venlafaxine, sold under the brand name Effexor among others, is an antidepressant medication of the serotonin–norepinephrine reuptake inhibitor (SNRI) class. It is used to treat major depressive disorder, generalized anxiety disorder, panic disorder, and social anxiety disorder. Studies have shown that venlafaxine improves post-traumatic stress disorder (PTSD). It may also be used for chronic neuropathic pain. It is taken orally (swallowed by mouth). It is also available as the salt venlafaxine besylate (venlafaxine benzenesulfonate monohydrate) in an extended-release formulation (Venbysi XR).
Common side effects include loss of appetite, constipation, dry mouth, dizziness, sweating, insomnia, drowsiness and sexual problems. Severe side effects include an increased risk of suicide, mania, and serotonin syndrome. Antidepressant withdrawal syndrome may occur if stopped. There are concerns that use during the later part of pregnancy can harm the baby. How it works is not entirely clear, but it seems to be related to the potentiation of the activity of some neurotransmitters in the brain.
Venlafaxine was approved for medical use in the United States in 1993. It is available as a generic medication. In 2022, it was the 44th most commonly prescribed medication in the United States, with more than 13 million prescriptions.

serotonin uptake inhibitor
A compound that specifically inhibits the reuptake of serotonin in the brain. This increases the serotonin concentration in the synaptic cleft which then activates serotonin receptors to a greater extent.
adrenergic uptake inhibitor
Adrenergic uptake inhibitors are drugs that block the transport of adrenergic transmitters into axon terminals or into storage vesicles within terminals. The tricyclic antidepressants and amphetamines are among the therapeutically important drugs that may act via inhibition of adrenergic transport. Many of these drugs also block transport of serotonin.
dopamine uptake inhibitor
A dopaminergic agent that blocks the transport of dopamine into axon terminals or into storage vesicles within terminals. Most of the adrenergic uptake inhibitors also inhibit dopamine uptake.
analgesic
An agent capable of relieving pain without the loss of consciousness or without producing anaesthesia. In addition, analgesic is a role played by a compound which is exhibited by a capability to cause a reduction of pain symptoms.
xenobiotic
A xenobiotic (Greek, xenos "foreign"; bios "life") is a compound that is foreign to a living organism. Principal xenobiotics include: drugs, carcinogens and various compounds that have been introduced into the environment by artificial means.
