Wellbutrin is the brand name for bupropion, an antidepressant that acts differently than typical selective serotonin reuptake inhibitors (SSRIs). It is a norepinephrine-dopamine reuptake inhibitor (NDRI), which means it boosts the neurotransmitters norepinephrine and dopamine. While it's often a good alternative for those who can't tolerate the sexual side effects of SSRIs, it can cause other gastrointestinal (GI) issues. Vomiting is a documented side effect, though it usually occurs early in treatment and is temporary.
Clinical trials have consistently shown that nausea and vomiting are common during the initial phase of Wellbutrin treatment. According to data from Drugs.com, up to 22.9% of patients taking Wellbutrin SR have reported nausea and vomiting. This initial gastrointestinal distress is believed to be a consequence of the body adjusting to the medication's effects, and it often resolves within two to three weeks. However, if it persists or becomes severe, it's crucial to consult a healthcare provider for further guidance.
The Link Between Wellbutrin and Vomiting
Unlike SSRIs, which primarily affect serotonin, Wellbutrin's mechanism of action focuses on dopamine and norepinephrine. The exact reason why this causes stomach upset is not fully understood, but it's likely related to the drug's effects on the central nervous system, which can influence digestive processes. Some patients may experience a general feeling of unease or motion sickness, which can trigger nausea and lead to vomiting.
Factors Influencing Wellbutrin-Induced Vomiting
Several factors can influence the likelihood and severity of vomiting while taking Wellbutrin:
- Dosage and Release Formula: Higher doses are more strongly associated with an increased risk of adverse effects. Additionally, the formulation can play a role. The immediate-release (IR) version, which has a higher peak concentration in the blood, can sometimes lead to more acute GI distress compared to the smoother, more gradual release of the sustained-release (SR) or extended-release (XL) versions.
- Individual Sensitivity: Every patient's body reacts differently to medication. Some individuals may be more sensitive to the neurological or physical effects of bupropion, leading to more pronounced GI symptoms. The temporary nature of the side effects is often a sign of the body acclimating to the new substance.
- Existing GI Conditions: People with pre-existing gastrointestinal issues may be more susceptible to nausea and vomiting when starting Wellbutrin. It is important to disclose any such conditions to your doctor before beginning treatment.
How to Manage Nausea and Vomiting from Wellbutrin
If you experience vomiting or significant nausea after starting Wellbutrin, there are several strategies you can employ to alleviate the symptoms. These methods focus on minimizing irritation and helping your body adjust more comfortably.
- Take with food: Consuming your dose with a meal or a small snack is often an effective way to reduce stomach upset and irritation.
- Eat smaller, more frequent meals: Overfilling the stomach can worsen nausea. Smaller, more frequent meals can help regulate digestion and keep your stomach from feeling empty.
- Stay hydrated: Sip on clear fluids like water or ginger ale (slightly flattened) throughout the day to prevent dehydration.
- Consider ginger: Ginger is a natural anti-emetic that can help with nausea. Try sipping ginger tea, eating ginger candies, or drinking ginger ale.
- Schedule strategically: If your symptoms are worst shortly after taking the medication, consider adjusting the timing. Taking your dose at bedtime, with your doctor's approval, can help you sleep through the peak of the side effects.
- Do not stop abruptly: Always consult your doctor before making any changes to your medication schedule. Stopping suddenly can lead to discontinuation syndrome, causing a variety of unpleasant symptoms, including nausea.
Comparing Wellbutrin and Other Antidepressants
When considering antidepressants, tolerability is a major factor. The following table provides a comparison of Wellbutrin and some common SSRIs concerning key side effects.
| Feature | Wellbutrin (Bupropion) | SSRIs (e.g., Zoloft, Paxil) |
|---|---|---|
| Mechanism | Norepinephrine-Dopamine Reuptake Inhibitor (NDRI) | Selective Serotonin Reuptake Inhibitor (SSRI) |
| Nausea/Vomiting | Common, especially at the start; often transient | Very common, especially at the start; some SSRIs can cause more significant GI issues |
| Sexual Side Effects | Low incidence; can even improve sexual function | High incidence of sexual dysfunction, including decreased libido |
| Weight Change | Often associated with weight loss | More commonly associated with weight gain |
| Energy Levels | Stimulating; can increase energy and reduce fatigue | Can cause drowsiness or insomnia depending on the specific SSRI |
When to Contact Your Healthcare Provider
While transient vomiting is often manageable, some symptoms require immediate medical attention. It is critical to differentiate between mild side effects and a serious adverse reaction.
Contact your doctor if:
- Vomiting is severe, persistent, or accompanied by other severe symptoms.
- You experience signs of an allergic reaction, such as a rash, hives, swelling, or difficulty breathing.
- You notice unusual changes in behavior, agitation, or worsening mental health symptoms.
- You have multiple seizures or experience a loss of consciousness.
It is important to remember that most side effects of bupropion are temporary. The body needs time to adjust to the medication, and patience is key. However, maintaining an open line of communication with your healthcare provider is the safest way to navigate treatment.

Conclusion
Yes, Wellbutrin can cause vomiting and nausea, and these are documented side effects of the medication, particularly in the initial weeks of treatment. Clinical trial data indicates a notable incidence of these gastrointestinal issues, but they are typically transient as the body acclimates. By implementing simple strategies such as taking the medication with food, eating smaller meals, and staying hydrated, many individuals can effectively manage the discomfort. Unlike many SSRIs, bupropion is less likely to cause sexual dysfunction or significant weight gain, making it a suitable alternative for some patients. If vomiting becomes severe, persistent, or is accompanied by other concerning symptoms, seeking immediate medical advice is essential. Never stop or adjust your medication without consulting a healthcare professional.
