Effexor withdrawal symptoms can be both emotionally and physically difficult. They can even be serious around 5 percent of the time.
The dosage and the length of time the drug was taken can influence the severity and duration of withdrawal symptoms.
Effexor withdrawal should be managed under the guidance of a medical professional. It should not be stopped suddenly. Tapering is the best approach to withdrawal.
Effexor is a brand-name formulation of the serotonin-norepinephrine reuptake inhibitor (SNRI) medication venlafaxine. SNRIs are typically prescribed to manage symptoms of depression.
Effexor and its generic form venlafaxine are prescribed to treat depression, generalized anxiety disorder (GAD), panic disorder, and social anxiety disorder. It is marketed as both an extended-release once-daily medication and as a formulation that needs to be taken two or three times a day.
Effexor works by interacting with brain chemistry, changing levels of neurotransmitters that regulate mood and energy, like serotonin and norepinephrine. When taken regularly, these alterations to brain chemistry are expected.
It often takes several weeks, and sometimes up to two months, for the medication to take full effect.
Effexor withdrawal occurs when the drug processes out of the brain and is no longer active in the bloodstream. Even missing one dose of Effexor when the brain expects it can result in mood swings and impairment.
Symptoms of Effexor withdrawal can even be severe enough to appear like a stroke. According to the U.S. Food and Drug Administration (FDA) labeling information for Effexor, the following are symptoms of withdrawal:
Some of these side effects can be extremely uncomfortable and potentially dangerous.
Due to the potential severity of Effexor withdrawal, don’t attempt to stop taking this medication on your own. Consult your doctor first.
Even if you have only been taking Effexor for a week or so, withdrawal symptoms can occur. The longer you have been taking the medication, the more intense withdrawal symptoms can be.

The dosage matters too. Generally, Effexor is given in as low a dose as possible initially. The dosage will be slowly increased over time until stabilization is reached. It can take up to six to eight weeks for the medication’s full impact to be felt.
Antidepressants are often taken on a long-term basis. The U.S. Centers for Disease Control and Prevention (CDC) publishes that about 25 percent of Americans taking antidepressants between 2011 and 2014 had been taking them for at least 10 years.
The higher the dosage and longer the medication has been taken, the more intense withdrawal symptoms will usually be.
Metabolism, genetics, additional medical and mental health concerns, and taking other medications or mind-altering substances can also contribute to the significance of Effexor withdrawal and its timeline.
In general, withdrawal symptoms can begin within 12 hours to a day of stopping the medication. Symptoms will generally be more intense if the medication is stopped suddenly.
The first week can be particularly uncomfortable, and symptoms will dissipate after that point. In some cases, they can last for several weeks to months, however.
Withdrawal side effects can be managed through a slow and controlled taper that lowers the dosage over time. Medications and supportive measures can be beneficial as well.
Effexor is typically weaned out of the body using a slow tapering of the dosage to manage and minimize withdrawal symptoms. This tapering approach may take anywhere from a few weeks to several months. It is influenced by the level of dependence that exists.
Effexor will need to be dosed at specific and set times to control potential withdrawal symptoms. The National Alliance on Mental Illness (NAMI) explains that your health care provider can determine your tapering schedule.
In additional to tapering using Effexor itself, other supportive medications may be helpful for specific withdrawal symptoms.
If you have abused Effexor in combination with other substances, it’s important to get help in a professional detox facility. Look for one that has immediate availability and can provide a seamless transition into a treatment program.
Detox programs that apply a comprehensive approach and aim to manage all aspects of withdrawal, including any underlying co-occurring disorders at the same time, can provide a good starting point for treating the person as a whole.
If you were taking Effexor for depression, you must make sure the condition is addressed via other means if you want to stop taking the medication. Talk to your doctor about alternatives if Effexor isn’t working for you.
Ultimately, you need a doctor managing your withdrawal process. You can’t do it on your own safely since the tapering schedule must be supervised by a physician.
There are some supportive methods that can help make the process more comfortable.
Effexor withdrawal can be managed with the help of trained professionals.
