Venlafaxine: A Versatile Antidepressant

Venlafaxine is a prescription medication primarily used to treat depression and social anxiety disorder. It belongs to a class of drugs called serotonin-norepinephrine reuptake inhibitors (SNRIs), which work by increasing the levels of two important neurotransmitters in the brain: serotonin and norepinephrine. This mechanism of action helps alleviate symptoms associated with mood disorders and anxiety.

Venlafaxine Uses

Venlafaxine oral tablets, available in both immediate-release and extended-release formulations, are used to treat the following conditions:

• Depression: Venlafaxine is approved for the treatment of major depressive disorder, helping to improve mood, interest in daily activities, and overall quality of life.
• Social Anxiety Disorder: The extended-release version of venlafaxine is specifically indicated for the treatment of social anxiety disorder, also known as social phobia.

Venlafaxine Dosage

The recommended dosage of venlafaxine varies depending on the condition being treated and the individual’s response to the medication. Here are some general guidelines:

Depression

The typical starting dose for venlafaxine immediate-release tablets is 75 mg taken twice daily. The dose may be increased in increments of 75 mg per day, up to a maximum of 375 mg per day, depending on the patient’s response and tolerance.

Social Anxiety Disorder

For the treatment of social anxiety disorder, the recommended starting dose of venlafaxine extended-release capsules is 75 mg once daily. The dose may be increased in increments of 75 mg per day, up to a maximum of 225 mg per day.

Serious Side Effects of Venlafaxine

Venlafaxine can also cause more serious side effects, which require immediate medical attention. These include:

• Suicidal thoughts or actions

If you experience any of these serious side effects, contact your healthcare provider right away or seek emergency medical care.

Venlafaxine Interactions and Precautions

Venlafaxine may interact with certain medications, including:

• Aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs), which can increase the risk of bleeding
• Anticoagulants (blood thinners) like warfarin, which can also increase the risk of bleeding

It’s important to inform your healthcare provider about all the medications, supplements, and herbal products you are taking to avoid potential interactions.

Additionally, venlafaxine should not be used in children and adolescents under the age of 18 due to the increased risk of suicidal thoughts and behaviors in this age group.
