If you’ve ever stopped taking antidepressants and felt a sudden jolt or zap in your head, you’re not alone. These sensations—often called withdrawal brain zaps—are common but poorly understood. Many describe them as brief electric shocks or buzzing in the brain, especially when moving their eyes or turning their head. Though not dangerous, brain zaps can feel alarming.
This article explains what causes brain zaps, how long they last, and how to manage them during antidepressant withdrawal.

What Are Brain Zaps?
Brain zaps—also known as brain shocks or brain shivers—are sudden, electrical-like jolts that people experience in the head, often during antidepressant withdrawal. Some describe the feeling as a zap that radiates from the brain to the rest of the body, while others say it’s more like a wave or vibration.
These sensory disturbances can come on suddenly, especially when moving your eyes quickly, turning your head, or waking up from sleep. While not life-threatening, brain zaps during withdrawal can interrupt your daily routine and affect your mental health.
What Causes Brain Zaps?
There’s no single answer to what causes brain zaps, but they appear most often after stopping antidepressants—especially selective serotonin reuptake inhibitors (SSRIs). These medications influence serotonin levels in the brain, and when you stop taking them suddenly, your brain may struggle to adjust. This imbalance likely contributes to symptoms like brain zaps.
Other potential triggers include:
- Rapid dose reduction instead of gradual tapering
- Taking medications with a short half-life
- Switching between different types of antidepressants
- Interrupting a prescription accidentally or due to side effects
How Long Do Brain Zaps Last?
You might wonder, how long do brain zaps last? The answer depends on your body, medication type, and how you stopped taking the drug.
For some people, brain zaps fade within a few days. For others, they can linger for weeks or even months. Typically, the symptoms are worse in the first few days after stopping antidepressants and gradually decrease as the brain rebalances its neurotransmitters.
If your symptoms continue for longer than expected, speak to a healthcare provider. Persistent zaps may indicate an underlying issue or the need for a slower tapering process.
Brain Zaps During Withdrawal: What to Expect
Brain zaps during withdrawal usually show up alongside other antidepressant withdrawal symptoms, such as:
- Dizziness or lightheadedness
- Mood swings, depression or anxiety
- Fatigue or insomnia
- Nausea or flu-like symptoms
- Poor concentration
- Irritability
These are all signs of antidepressant discontinuation syndrome, a temporary condition that occurs when the body reacts to reduced serotonin levels. Not everyone will get brain zaps, but people experience different reactions depending on the medication and tapering speed.
Brain Zaps After Stopping Medication: When to Be Concerned
While brain zaps after stopping medication are generally harmless, some individuals report difficulty focusing, disrupted sleep, or trouble completing daily tasks. If you’re also experiencing eye movements that feel jerky or triggering zaps, or if you’re dealing with other severe withdrawal symptoms, it’s important to talk to a medical professional.
In rare cases, the discomfort can interfere with recovery from mental health conditions like depression. Staying in contact with your doctor can help reduce risks and make your transition off medication smoother.
How to Stop Brain Zaps: Practical Tips
Wondering how to stop brain zaps? While there’s no instant cure, several strategies can reduce their frequency and intensity:
1. Taper Off Slowly
Gradual tapering is one of the most effective ways to avoid withdrawal symptoms. Never stop antidepressants cold turkey without medical supervision. A slower reduction of your dose allows your brain time to adapt.
2. Talk to Your Doctor
If you’re experiencing brain zaps, let your provider know. They may adjust your tapering schedule, prescribe a medication with a long half-life, or recommend supplements that support the nervous system.
3. Prioritize Sleep and Hydration
Sleep deprivation can make withdrawal symptoms worse. Drink plenty of fluids, get rest, and avoid stimulants like caffeine.
4. Manage Stress
Stress can heighten symptoms of antidepressants withdrawal. Try meditation, breathing exercises, or talking with a therapist to stay emotionally balanced.
5. Avoid Alcohol and Recreational Drugs
These substances can interfere with brain recovery and make brain zaps feel more intense. Focus on gentle healing and avoid anything that stresses your nervous system.
Coping with Brain Zaps: What Helps in the Moment
Even if you’re following a taper plan, you might still get the occasional jolt. Here are quick ways for coping with brain zaps:
- Breathe deeply and stay calm when a zap hits
- Move slowly—sudden eye movements may trigger zaps
- Ground yourself with physical sensations (like holding a cold object or focusing on textures)
- Use distractions like music or guided meditations to shift attention
Should You Be Worried?
In most cases, withdrawal brain zaps go away on their own. But if they persist, worsen, or interfere with daily life, reach out to your healthcare provider. Proper monitoring is important—especially if you’re at risk of depression or anxiety returning after stopping antidepressants.
The good news? Brain zaps are a sign that your brain is recalibrating. With the right care, they usually pass.
When Professional Help Is the Best Option
If brain zaps occur alongside severe mood changes, suicidal thoughts, or worsening mental health, don’t wait to seek help. These may be signs that withdrawal is triggering a relapse or that the withdrawal symptoms are too strong to handle alone.
