What Is Wellbutrin (Bupropion)?
Wellbutrin, also known by its generic name
Wellbutrin affects the balance of certain chemicals in the brain, particularly norepinephrine and dopamine, which are neurotransmitters involved in mood regulation. It is believed that by increasing the levels of these neurotransmitters, Wellbutrin helps to alleviate depressive symptoms.
There are numerous other brand names and generic versions of bupropion available, including:
- Wellbutrin SR
- Wellbutrin XL
- Forfivo XL
Difference Between Wellbutrin SR and Wellbutrin XL
Wellbutrin SR (sustained-release) and Wellbutrin XL (extended-release) are different formulations of the medication bupropion. They differ in terms of their approved indications, release mechanisms, dosing schedules, and some other aspects. Here is a breakdown of the main differences.
Major depressive disorder
Major depressive disorder and prevention of seasonal affective disorder

150 mg and 300 mg
It is typically taken twice daily, with a gap of minimum 8 hours between doses.
It is typically taken once daily. When it comes to medication adherence in certain patients, it may be preferred by doctors due to once-daily dosing.
What Are the Uses of Wellbutrin?
Wellbutrin is FDA-approved and commonly prescribed to manage major depressive disorder (
Wellbutrin is also prescribed off-label for other conditions, including attention deficit hyperactivity disorder (ADHD), obesity, bipolar disorder associated with depression, and sexual dysfunction caused by antidepressants.
It’s important to note that Wellbutrin may take several weeks to reach its full effectiveness for mental illness, and it should be taken exactly as prescribed by a healthcare provider. Dosage and treatment duration vary depending on the individual and their specific condition.
How Does Wellbutrin Affect Weight?
When it comes to body weight, the effects of Wellbutrin vary from person to person. Unlike some other antidepressants, Wellbutrin is generally considered weight-neutral or may result in slight weight loss in most individuals. However, some people may experience weight gain while taking Wellbutrin due to various reasons.
Wellbutrin and Weight Gain
Wellbutrin (bupropion) is generally considered to have a lower risk of causing weight gain compared to many other antidepressant medications. However, it’s important to note that individual responses can vary, and some people may still experience
Weight gain as a side effect of Wellbutrin is relatively uncommon. It tends to occur less frequently and to a lesser extent than such an effect of other

Wellbutrin and Weight Loss
Some individuals may experience significant weight loss or decreased appetite while taking Wellbutrin which is more prevalent than the opposite effect. The exact mechanism by which Wellbutrin may contribute to weight loss is not fully understood. However, a few potential factors could be involved:
- Appetite suppression. Wellbutrin may affect the levels of certain neurotransmitters in the brain, such as dopamine and norepinephrine, which can cause loss of appetite in some individuals. This can lead to decreased food intake and potentially result in weight loss.
- Increased energy expenditure. Wellbutrin may increase metabolic rate or energy expenditure in some people. This can cause a slight boost in calorie burning and potentially contribute to weight loss.
- Smoking cessation. Wellbutrin is also prescribed for smoking cessation, and quitting smoking may lead to weight loss. If Wellbutrin is being used for smoking cessation, any weight loss can be a result of quitting smoking rather than a direct effect of the medication on weight itself.
It’s important to remember that not everyone using Wellbutrin will lose weight, and its effects can differ from person to person. Additionally, any weight reduction linked to Wellbutrin is often slow and gradual. If the possibility of losing weight disturbs you, consult your healthcare provider to know how to manage this effect or choose another treatment option.
Do Other Antidepressants Cause Weight Gain?
Weight gain is a potential side effect associated with antidepressant medications. However, not all antidepressants cause weight gain, and the extent varies. The relationship between antidepressants and weight changes is complex and can be influenced by several factors, including the specific medication, the individual’s metabolism, lifestyle, and underlying medical conditions.
Certain classes of antidepressants are more commonly associated with weight gain than others. For example, tricyclic antidepressants (TCAs), such as amitriptyline and nortriptyline, have a higher likelihood of
Selective serotonin reuptake inhibitors (SSRIs), such as fluoxetine (Prozac), sertraline (Zoloft), and escitalopram (Lexapro), are generally considered to have a lower risk of causing weight gain. However, weight changes can still occur with
Other antidepressants, such as serotonin-norepinephrine reuptake inhibitors (

In a Nutshell
While weight changes can occur with any medication, bupropion isn’t associated with the same risk of changes in body mass as other medications for depression.
