Serotonin-norepinephrine reuptake inhibitors (SNRIs) are a class of antidepressant medications used to treat conditions like depression, anxiety, and chronic pain. While they can be helpful for many, stopping them suddenly or without proper medical guidance can lead to uncomfortable and sometimes serious withdrawal symptoms. This article explains SNRIs withdrawal symptoms, what you need to know, what to expect, and when to seek help.

Why SNRI Withdrawal Happens
SNRIs increase levels of serotonin and norepinephrine in the brain, which are two chemicals involved in mood regulation. When you take these medications over time, your brain adjusts to the higher levels of the medication. If you abruptly quit taking the drug, your brain doesn’t have time to readjust. This can lead to withdrawal symptoms, and the reaction is sometimes referred to as “SNRIs withdrawal syndrome.”
Common SNRIs Linked to Withdrawal Symptoms
When it comes to SNRIs, withdrawal effects manifest differently depending on the prescription drug you’re taking. Some are more likely to cause symptoms than others. Examples of drugs with potentially higher withdrawal complications include:
- Venlafaxine (Effexor)
- Desvenlafaxine (Pristiq)
- Duloxetine (Cymbalta)
- Levomilnacipran (Fetzima)
Effexor, in particular, is known for causing more intense withdrawal symptoms due to its short half-life.
Physical Symptoms of SNRI Withdrawal
Withdrawal from SNRIs can lead to a wide range of physical symptoms. These often appear within a few days of stopping the medication, especially if it was stopped suddenly. Common physical symptoms may include:
- Dizziness or lightheadedness
- Flu-like symptoms (fatigue, chills, muscle aches)
- Headaches
- Nausea or vomiting
- Electric shock sensations (often called “brain zaps”)
- Problems with balance or coordination
These symptoms can be uncomfortable but are usually not life-threatening. However, they can interfere with daily functioning.
Mental and Emotional Symptoms of SNRI Withdrawal
Emotional and psychological complications with SNRIs and withdrawal symptoms are also common. These emotional side effects may include:
- Mood swings
- Anxiety or restlessness
- Irritability or anger
- Depressed feelings
- Difficulty concentrating
- Insomnia or vivid dreams
For some, these symptoms may feel similar to a return of their original condition, but they are often short-term effects of stopping the medication too quickly.
How Long Do SNRI Withdrawal Symptoms Last?
The duration of withdrawal varies depending on several factors:
- Which SNRI you were taking
- How long you were on it
- The dosage
- Whether you tapered or stopped suddenly
The phases of SNRIs withdrawal may begin within a few days and could possibly last one to three weeks. For some, especially those who stopped abruptly, symptoms can persist longer.
The Importance of Tapering Off Safely
To reduce the risk of withdrawal symptoms, it’s important to taper off SNRIs slowly under the guidance of a medical professional. Tapering involves gradually reducing the dose over time, allowing your brain to adjust.
Never attempt to quit “cold turkey” without medical supervision, even if you feel like the medication isn’t helping or you’re experiencing side effects. Doing so can make withdrawal more intense and increase the risk of relapse or emotional distress.
When to Seek Professional Help
If you’re struggling with how to deal with SNRIs withdrawal, do not hesitate to get help. Furthermore, you should reach out to a healthcare provider immediately if you are experiencing the following:
- Suicidal thoughts or self-harming behavior
- Panic attacks or extreme anxiety
- Hallucinations or paranoia
- Withdrawal symptoms that do not improve after a few weeks
- Difficulty managing daily responsibilities

Why SNRI Withdrawal Can Be Mistaken for Relapse
One of the most confusing parts of SNRI withdrawal is that symptoms may mimic the condition the medication was originally treating. For example, anxiety, insomnia, or sadness may return. However, withdrawal symptoms tend to come on quickly and fade over time, whereas a relapse tends to develop more gradually and persist.
A healthcare provider can help determine whether what you’re feeling is withdrawal or a return of symptoms, and what next steps are right for you.

FAQs About SNRIs Withdrawal Symptoms
How can I tell the difference between withdrawal and relapse?
Withdrawal symptoms usually appear quickly after stopping a medication and often improve within a few weeks. A relapse tends to come on more slowly and last longer. A medical professional can help tell the difference.
Can SNRI withdrawal cause seizures?
When discontinuing SNRIs, withdrawal symptoms like seizures aren’t common, but they can occur in rare cases, especially when stopping high doses suddenly. Always consult a doctor before making any changes to your medication.
Is it safe to switch from one SNRI to another?
Switching medications may be necessary in some cases and can be done safely with a doctor’s guidance. However, switching without proper tapering can increase the risk of withdrawal or side effects.
Can you die from SNRI withdrawal?
While it is extremely rare to die from SNRI withdrawal itself, the symptoms can lead to dangerous behaviors or mental health crises if left untreated. This is why professional oversight is important if you’re concerned about discontinuing usage of SNRIs and withdrawal symptoms.
