Doctors prescribe venlafaxine ER to treat several mental health conditions, such as major depressive disorder (depression) and various anxiety disorders including:
Venlafaxine ER may be prescribed with other treatment strategies like therapy and lifestyle adjustments.
Venlafaxine ER belongs to a class of drugs known as serotonin and norepinephrine reuptake inhibitors (SNRIs). Serotonin and norepinephrine are chemical messengers (neurotransmitters) responsible for regulating 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.
Venlafaxine ER is available as an extended-release oral 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.
Venlafaxine ER is used to manage depression, anxiety, and panic disorder. The effects can be noticeable within a few weeks, but it may take several weeks to achieve the desired improvement in symptoms.
Continue using venlafaxine ER as prescribed, even if you start feeling better. Regular use according to your prescription is crucial for the management of your condition.
