Wellbutrin can cause anxiety, especially when you first start taking it or when your dose changes. This is a known side effect of the medication, though it does not happen to everyone. For many people, any anxious feelings are temporary and fade as the body adjusts to the medicine.
Does Wellbutrin Cause Anxiety?
Yes, anxiety is a documented side effect of bupropion, which is the generic name for Wellbutrin. Clinical trials and decades of real-world use have confirmed this. The medication works by increasing levels of dopamine and norepinephrine in the brain. These are stimulating chemicals, and that stimulation can feel like nervousness or anxiety.
The effect is most common in the first few weeks of treatment. It can also appear when your doctor increases your dose. For some people, the anxiety is mild and passes quickly. For others, it can be more intense and hard to manage.
This side effect is common enough that doctors specifically ask about it when prescribing the drug. It is one of the main reasons some people stop taking Wellbutrin. If you are considering this medication, knowing this risk ahead of time helps you prepare.
How Common Is Anxiety With Wellbutrin?
Anxiety is one of the more frequently reported side effects of Wellbutrin. Studies and clinical experience show that a meaningful number of people experience increased anxiety or agitation while taking it. The exact percentage varies depending on the study and the dose used.
Higher doses are generally associated with a higher risk of anxiety. The standard starting dose is often 150 mg per day, usually in an extended-release form. If the dose is raised to 300 mg, the chance of feeling anxious tends to go up.
People who already struggle with anxiety may be more sensitive to this effect. That does not mean they cannot take Wellbutrin. It just means the decision requires careful thought and close monitoring by a doctor.
Why Does Wellbutrin Cause Anxiety?
Wellbutrin is a norepinephrine-dopamine reuptake inhibitor, or NDRI. It blocks the reuptake of these two neurotransmitters, leaving more of them available in the brain. This is different from SSRIs, which mainly affect serotonin.
Norepinephrine is tied to alertness and the body’s stress response. When levels rise, you may feel more awake and focused. But the same chemical boost can trigger physical symptoms of anxiety, such as a racing heart or a jittery feeling.
Dopamine also plays a role. It is linked to motivation and reward, but too much stimulation in certain brain pathways can contribute to agitation. The combination of these two effects is what makes Wellbutrin energizing for some people and anxiety-provoking for others.
This is not a sign that the drug is wrong for you. It is a predictable response to how the medication works. Understanding the mechanism does not make the feeling pleasant, but it can make it less frightening.
How Long Does Anxiety From Wellbutrin Last?
For most people, anxiety from Wellbutrin peaks in the first one to two weeks. As the brain adjusts to the new chemical balance, the side effect often lessens. Many people find that by the end of the third or fourth week, the anxious feeling has mostly faded.
This adjustment period is not guaranteed. Some people continue to feel anxious for as long as they take the medication. Others find that the anxiety only appears when the dose increases, then settles again after a few weeks.
If the anxiety is severe or does not improve after a few weeks, tell your doctor. Persistent anxiety can be a sign that Wellbutrin is not the right medication for you. There are other antidepressants that work through different pathways and may be better tolerated.
What Does Wellbutrin Anxiety Feel Like?
Anxiety from Wellbutrin can feel different from person to person. Some describe it as a general sense of restlessness or being on edge. Others report physical symptoms, such as a pounding heart, sweating, or trouble sleeping.
It can also feel like an internal trembling that is hard to pinpoint. You might find yourself worrying more than usual, or feeling irritable without a clear reason. Some people experience a sense of dread that does not match their actual circumstances.
These feelings can be distressing, especially if you started Wellbutrin to feel better, not worse. It helps to remember that this is a known side effect, not a sign that you are failing at treatment or that something is wrong with you.
Can Wellbutrin Help With Anxiety?
Wellbutrin is not approved by the FDA to treat anxiety disorders. It is primarily prescribed for depression and seasonal affective disorder. It is also used to help people quit smoking under the brand name Zyban.
Some doctors prescribe it off-label for anxiety, especially when depression and anxiety occur together. The evidence for this use is limited. Some people do report that their anxiety improves once their depression lifts, because the two conditions often feed into each other.
However, for most people with a primary anxiety disorder, other medications are usually a better first choice. SSRIs and SNRIs have stronger evidence for treating anxiety. They also tend to be less activating than Wellbutrin.
If your doctor suggests Wellbutrin and you have a history of anxiety, ask why. There may be a good reason, such as avoiding SSRI side effects like weight gain or sexual dysfunction. But you deserve a clear explanation of the risks and benefits.
What to Do If Wellbutrin Makes You Anxious
If you start feeling anxious on Wellbutrin, do not stop the medication on your own. Stopping suddenly can cause withdrawal symptoms, including irritability and mood changes. It can also make your original depression symptoms return quickly.
Contact your prescribing doctor and describe what you are feeling. Be specific about when the anxiety started, how severe it is, and whether it is interfering with your daily life. This information helps your doctor decide what to do next.
Your doctor may suggest one of several options:
- Waiting a bit longer to see if the anxiety fades on its own
- Lowering your current dose
- Switching to a different antidepressant
- Adding a short-term anti-anxiety medication while you adjust
In the meantime, basic coping strategies can help. Deep breathing, short walks, and limiting caffeine can all reduce the physical feelings of anxiety. Caffeine is especially important to watch, since it adds to the stimulating effect of Wellbutrin.
Who Should Avoid Wellbutrin?
Wellbutrin is not right for everyone. People with a history of seizures should generally avoid it, because the medication lowers the seizure threshold. This is why the FDA includes a warning about seizure risk on the label.
People with a history of eating disorders, such as anorexia or bulimia, also face a higher seizure risk with Wellbutrin. The same applies to people going through alcohol or benzodiazepine withdrawal. These conditions make the brain more prone to seizures.
If you have severe anxiety or panic disorder, your doctor may think twice before prescribing Wellbutrin. The activating nature of the drug can worsen these conditions. That does not mean it is never used, but it means the decision requires careful thought.
