What is venlafaxine?

Venlafaxine is a prescription medication used to treat major depressive disorder and various anxiety disorders, such as generalized anxiety disorder, social anxiety disorder, and panic disorder.

What is venlafaxine used to treat?

Doctors prescribe venlafaxine to treat several mental health conditions, such as major depressive disorder (depression) and various anxiety disorders such as:

  • Generalized anxiety disorder
  • Social anxiety disorder
  • Panic disorder

Venlafaxine may be prescribed with other treatment strategies like therapy and lifestyle adjustments.

How does venlafaxine work?

Venlafaxine belongs to a class of drugs known as selective serotonin and norepinephrine reuptake inhibitors (SNRIs). Serotonin and norepinephrine are chemical messengers (neurotransmitters) responsible for regulating your mood and helping you feel happy. These hormones are produced naturally by the neurons in your brain and are used to send signals between neurons (or nerves). Once a signal has been sent, the neuron reabsorbs the serotonin and norepinephrine to be recycled.

Sometimes neurons reabsorb these hormones too quickly - before they can tell your brain to feel happy - resulting in low levels of these mood-regulating chemicals. Reducing the brain’s reuptake of serotonin and norepinephrine can help balance your mood and relieve several conditions, such as stress, anxiety, and depression.

How do I take venlafaxine?

Venlafaxine is available as an oral tablet and extended-release capsule.

The dosage and frequency of use depend on the condition being treated, its severity, and how you respond to the medication.

Follow your healthcare provider's instructions regarding dosage and schedule. Do not exceed the prescribed dose or frequency of use without consulting your provider.

How long until I feel better?

Venlafaxine is used to manage depression, anxiety, and panic disorder. The effects can be noticeable within a few weeks, but it may take up to several weeks to achieve the desired improvement in symptoms.

Continue using venlafaxine as prescribed, even if you start feeling better. Regular use according to your prescription is crucial for the management of your condition.

Are there any other uses for venlafaxine?

While venlafaxine is primarily used for treating depression, anxiety, and panic disorder, healthcare providers may prescribe it off-label for other conditions.

Discuss any alternative uses of venlafaxine with your healthcare provider.
