Wellbutrin has a widely available generic version (bupropion) that is typically less expensive than the brand name and is more likely to be covered by health insurance.
Both Wellbutrin and generic Wellbutrin contain the same active ingredient and work similarly, though they may differ in inactive ingredients and physical appearance.
Most people find that both versions of Wellbutrin work equally effectively and have similar side effects, though some people may notice differences when switching.
Wellbutrin is a type of antidepressant known as a norepinephrine–dopamine reuptake inhibitor (NDRIs) that is approved to treat mental health conditions like major depressive disorder (MDD) and seasonal affective disorder (SAD). It is available as a 12-hour sustained-release formulation (Wellbutrin SR) and a 24-hour extended-release formulation (Wellbutrin XL). The active ingredient bupropion is also sold as Zyban, which is approved to help with smoking cessation. Generic Wellbutrin XL has been available in the U.S. since 2006, but generic forms of the immediate-release and sustained-release formulations became available even earlier.

Is there a generic for Wellbutrin?
Yes, there are generic versions of Wellbutrin. Wellbutrin’s generic name is bupropion, and the FDA approved it for use in the early 2000s. Generic versions of medications are generally cheaper and are more likely to be covered by your health insurance. This means that generic Wellbutrin may be more available and accessible to many people.
What are the differences between generic vs. brand-name Wellbutrin?
Generic Wellbutrin is available in immediate-release (IR), sustained-release (SR), and extended-release (XL) forms. Brand-name Wellbutrin SR and Wellbutrin XL are available in SR and XL forms, while the original brand-name immediate-release Wellbutrin has been discontinued.
But while some inactive ingredients may differ between generic Wellbutrin and brand-name Wellbutrin, both medications contain the same active ingredient. “The FDA requires generics to be bioequivalent, meaning they must deliver the same amount of medication into the bloodstream in a similar time frame,” explains Caitlyn McClure, DSW, vice president of clinical services at Northern Illinois Recovery.
While the medications should work the same way, some people notice differences, especially in side effects. “Some patients report differences when switching, which may be due to inactive ingredients, absorption rates, or individual sensitivity,” Dr. McClure says. “These differences can affect side effects or how well the medication feels like it is working.”
In 2012, the FDA removed one generic Wellbutrin product, Budeprion XL 300 mg tablets, manufactured by Impax, from the market. It was found that this generic version was not therapeutically equivalent to Wellbutrin. Since then, various studies, including a 2019 randomized clinical trial published in Clinical Pharmacology & Therapeutics, have shown that the current generic Wellbutrin medications on the market are comparable to brand-name Wellbutrin.
“There are multiple randomized, double-blind crossover studies showing that generic bupropion XL 300 mg formulations are bioequivalent to the brand product,” explains Brian Zachariah, MD, a board-certified psychiatrist with Mindpath Health. “These studies also found no clinically meaningful differences in efficacy or side effect profiles between generic and brand formulations.”
How much does generic Wellbutrin cost?
Generic Wellbutrin tends to be much more affordable than brand-name Wellbutrin. For a 30-day supply of brand-name Wellbutrin 300 mg tablets, the retail cost can average over $3,000. In contrast, purchasing the generic version with a SingleCare discount card could mean paying around $15, depending on the pharmacy and location.

What are the off-label uses for Wellbutrin?
Wellbutrin is officially approved to treat depression in adults and seasonal affective disorder. But it’s also often used off-label for other conditions. “Off-label, both brand and generic bupropion, are sometimes used for ADHD, bipolar disorder, weight management, and to counter sexual side effects from other antidepressants,” Dr. McClure says.
Is Wellbutrin covered by insurance?
Most health insurance plans cover generic Wellbutrin. Because it’s an established generic medication, it’s usually on a lower formulary tier (Tier 1 or Tier 2), which means lower copays for most patients.
Brand-name Wellbutrin, on the other hand, is more often on a higher formulary tier or may require prior authorization before your insurance will cover it. Coverage varies by plan, so it’s best to check with your insurance provider or pharmacist before filling a prescription.
How do you get Wellbutrin covered by insurance?
If your insurance plan covers generic Wellbutrin, you can typically fill your prescription at any in-network pharmacy and pay your standard generic copay. If you or your healthcare provider prefers brand-name Wellbutrin for medical reasons, your provider may need to submit a prior authorization request to your insurance company explaining why the brand name is medically necessary.
If insurance does not cover the cost of your prescription, or if you are uninsured, a SingleCare discount card may help lower the price of both generic and brand-name Wellbutrin at participating pharmacies.
Generic alternatives to Wellbutrin
There are several Wellbutrin alternatives your healthcare provider may prescribe if bupropion isn’t right for you. Many of these alternatives have generic versions available, which may be more accessible. Common alternatives to Wellbutrin with generic forms include:
- Sertraline (generic Zoloft): a selective serotonin reuptake inhibitor (SSRI) commonly used to treat depression and anxiety disorders
- Fluoxetine (generic Prozac): an SSRI approved for depression, OCD, panic disorder, and other conditions
- Escitalopram (generic Lexapro): an SSRI used for major depressive disorder and generalized anxiety disorder
- Venlafaxine (generic Effexor XR): a serotonin-norepinephrine reuptake inhibitor (SNRI) used for depression and anxiety
- Duloxetine (generic Cymbalta): an SNRI used for depression, anxiety, and certain chronic pain conditions
Your healthcare provider can help determine which antidepressant is best for you based on your overall medical history. If you are using bupropion for smoking cessation, varenicline (generic Chantix) is another FDA-approved option that your provider may discuss with you.
How to switch from Wellbutrin to bupropion
It’s usually simple and easy to switch from Wellbutrin to generic Wellbutrin. “Switching from brand to generic usually does not require tapering because the active drug is the same,” Dr. McClure explains. What matters most is that you stay consistent with whatever formulation you’ve been taking, whether an immediate-release, sustained-release (SR), or extended-release (XL) dosage, according to Dr. McClure.
It’s also important not to miss doses when switching from one version of Wellbutrin to another. “If doses are missed, some people can experience withdrawal-like symptoms such as irritability, anxiety, or sleep changes,” Dr. McClure describes. These symptoms are not life-threatening, according to Dr. McClure, but they can be uncomfortable, which is why you should not miss a dose of bupropion when switching.
Although most prescribers will have no problem switching you from brand-name Wellbutrin to generic Wellbutrin, there are times when the brand name may be preferred. “For example, if a patient has tried multiple generics and experienced inconsistent results or significant side effects, a provider may request the brand to ensure stable delivery,” Dr. McClure says. While this is not a common scenario, it can happen, “especially in patients with a history of sensitivity to medication changes,” Dr. McClure shares.
Above all, if you have continued questions about switching to Wellbutrin generic from brand-name Wellbutrin, you shouldn’t hesitate to seek medical advice from a healthcare professional or pharmacist.
Expert takeaway
Most patients can switch from brand-name to generic Wellbutrin and experience the same effectiveness. However, those who see changes in how their medication feels should consult their healthcare provider instead of stopping treatment on their own.
