Can Auvelity cause weight loss or weight gain?

It isn’t likely. Weight loss and weight gain were not reported in studies of Auvelity.

But weight changes can occur in people with MDD, which Auvelity is prescribed to treat.

Talk with your doctor if you have questions about your weight while taking Auvelity.

Can Auvelity cause withdrawal symptoms?

It’s possible. Although it wasn’t reported in studies, Auvelity may cause antidepressant discontinuation syndrome (also known as antidepressant withdrawal). These are symptoms that can occur because you suddenly stop taking an antidepressant. They occur because of how the drug works in your body to change certain neurotransmitter levels in your brain.

Typically, withdrawal symptoms can include:

It’s not recommended to suddenly stop taking Auvelity or other antidepressants. If you no longer wish to take Auvelity or other antidepressants, talk with your doctor first. They’ll take you off the medication slowly to decrease your risk of antidepressant withdrawal symptoms.

Talk with your doctor if you have concerns about withdrawal symptoms.

How long do Auvelity side effects last? Will these side effects go away?

It depends. Certain side effects will last a few days. Others may continue for weeks or months.

Long-term side effects can also occur. These are side effects that may not go away, sometimes even after you stop taking the drug. They may start at any time during your treatment, even if you’ve taken the drug for a long time.

Risk of suicidal thoughts and behaviors

Auvelity has a boxed warning for the risk of suicidal thoughts and behaviors. A boxed warning is the most serious warning from the FDA.

Studies included people taking medications similar to Auvelity (antidepressants). In these studies, people ages 24 years and younger were reported to have an increased risk of suicidal thoughts and behaviors. People with MDD also were more likely to have an increased risk of suicidal thoughts and behaviors.

Suicidal thoughts can sometimes be a symptom of MDD. Typically, this risk is also higher during the first few months of treatment and when the dose is changed. It’s unknown whether this risk continues with long-term use of Auvelity and other antidepressants. Long-term use is usually beyond 4 months.

Auvelity is not approved for use in children.

Suicidal thoughts and behaviors can cause symptoms such as:

  • sudden changes in mood, thoughts, behavior, and feelings
  • new or worsening depression, anxiety, or irritability
  • anger, violence, or aggression
  • thoughts about dying or harming oneself

What might help

If you experience the above symptoms during your Auvelity treatment, talk with your doctor right away. If you have thoughts about harming yourself, call 911 or your local emergency number immediately. You can also call or text the 988 Suicide & Crisis Lifeline at 988.

Multiple factors can increase your risk of seizures. Some of these risk factors include:

  • taking Auvelity with certain other medications, including those that contain bupropion

What might help

Talk with your doctor about your health history and the medications you take. Be sure to include prescription medications, supplements, and over-the-counter medications.

Certain seizures can be considered a medical emergency. If you experience symptoms of a seizure, call 911 or your local emergency number immediately.
