Description
Venlafaxine ER is an FDA-approved SNRI (serotonin-norepinephrine reuptake inhibitor) used to treat major depressive disorder (MDD), generalized anxiety disorder (GAD), social anxiety disorder, and panic disorder. The extended-release formulation delivers the medication gradually over time. When prescribed appropriately, patients may notice a meaningful reduction in persistent sadness and excessive worry.

How to use

Take venlafaxine by mouth once a day with food, at the same time each day, or as directed by your QuickMD doctor. If you are taking the extended-release capsule, swallow it whole. Do not crush, chew, or open it. Venlafaxine should always be taken with food to help reduce nausea. Do not take it more often than directed, and do not stop taking it suddenly without speaking to your doctor first.

Frequently asked questions

Should I take venlafaxine in the morning or at night?

Some patients find it works best in the morning, particularly if it affects their sleep. Others prefer taking it at night if they notice any drowsiness. The most important thing is to take it at the same time each day and always with food to help reduce nausea.

Does venlafaxine cause weight gain?

Weight changes are possible with venlafaxine, though they tend to be modest and vary from person to person.

How long does venlafaxine stay in your system?

Venlafaxine works relatively quickly in the body and clears out faster than many other antidepressants. In most patients, venlafaxine may fully clear from the system within a few days of stopping.
