Wellbutrin, also known as bupropion, is an antidepressant medication commonly used to treat major depressive disorder (MDD) and seasonal affective disorder (SAD). While it is primarily prescribed for mental health conditions, some people have experienced weight loss as a side effect. This article explores how Wellbutrin can potentially aid in weight loss, how long it takes to work, and what to expect during treatment.
What is Wellbutrin?
Wellbutrin is an antidepressant medication that affects neurotransmitters in the brain. It is an atypical antidepressant that belongs to the norepinephrine-dopamine reuptake inhibitor (NDRI) class of drugs. Unlike most antidepressants, which primarily affect serotonin levels, Wellbutrin primarily affects dopamine and norepinephrine levels. These neurotransmitters play a crucial role in regulating mood, energy, motivation, and appetite.
Wellbutrin comes in different forms, including:
- Wellbutrin: This is the immediate-release form, typically taken multiple times a day.
- Wellbutrin SR (Sustained Release): This form is absorbed more quickly by the body and is generally taken twice per day. SR is used to treat major depressive disorder and quitting smoking (smoking cessation).
- Wellbutrin XL (Extended Release): This form is absorbed more slowly by the body and is taken once daily. XL is used to treat depression and seasonal affective disorder (SAD).
How Wellbutrin Works for Weight Loss
While Wellbutrin is not FDA-approved specifically for weight loss, it can have an impact on weight due to its effects on neurotransmitters. Here are some of the ways Wellbutrin may contribute to weight loss:
- Appetite Suppression: Wellbutrin can suppress appetite in some people by affecting dopamine and norepinephrine levels. These neurotransmitters play a role in regulating appetite, satiety, and eating behaviors.
- Increased Energy and Motivation: Wellbutrin can increase energy levels and motivation, which can lead to a more active lifestyle and better eating habits.
- Improved Mood: By improving overall mood and reducing symptoms of depression, Wellbutrin may indirectly contribute to weight loss by promoting healthier behaviors and reducing emotional eating.
It's important to note that the weight loss effects of Wellbutrin can vary from person to person and may not occur at all if the medication is not paired with healthy lifestyle changes, such as diet and exercise.

How Long Does Wellbutrin Take to Work for Weight Loss?
The timeline for Wellbutrin to start working for weight loss can vary. Some people may notice changes in their appetite or weight within the first 1-2 weeks of starting the medication, but for most people, it can take up to 8 weeks to see a noticeable reduction in weight.
Small studies have shown that approximately 67% of people who take bupropion are able to lose over 5% of their baseline body weight (compared to 15% in the placebo group) during the first eight weeks. People who have responded to bupropion and continue taking it for 24 weeks can achieve a weight loss of almost 12.9% from their baseline body weight, with fatty tissue accounting for 74% of the total weight loss.
It's important to be patient and consistent with your treatment plan. Weight loss on Wellbutrin may not be linear, and it's normal to experience fluctuations in weight.
Signs That Wellbutrin is Working
Besides weight loss, there are other signs that Wellbutrin is working effectively. These include:
- Improved Mood: Less sadness, less crying, and an overall improved outlook on life.
- Better Sleep: Improvements in insomnia, such as easier time falling asleep, less restlessness during the night, and less waking up early in the morning.
- Increased Energy: Less fatigue throughout the day and less feeling of heaviness in the limbs.
- Reduced Social Anxiety: Easier to participate in and enjoy social activities.
- Improved Focus and Concentration: Enhanced ability to sit still, focus on the activity at hand, and lower distractibility.
- Increased Appetite and Enjoyment of Food: Less GI upset, less constipation, and better appetite. A renewed interest in food that otherwise did not bring joy.
If you experience these positive changes, it's a good indication that Wellbutrin is working for you.

Factors That Can Affect How Well Wellbutrin Works
Several factors can affect how long Wellbutrin takes to work and how effective it is for weight loss. These include:
- Dosage: Adjusting the dose of Wellbutrin can affect how long it takes to work. Your doctor may want to increase the dose if it’s been long enough to know that your current dose isn’t working as it should. Higher doses might lead to a faster onset of action.
- Individual Factors: Body chemistry and genetics can significantly impact how long a drug takes to work.
- Lifestyle: Diet, exercise, and sleep habits can all influence the effectiveness of Wellbutrin for weight loss.
- Medications: Every drug can potentially interact with other medications.
Important Considerations Before Taking Wellbutrin for Weight Loss
Before starting Wellbutrin for weight loss, it's essential to consider the following:
- Consultation with a Healthcare Provider: It’s essential to consult with a healthcare provider who can evaluate symptoms, medical history, current medications, and any potential contraindications or risks.
- Primary Use: Keep in mind that Wellbutrin is primarily prescribed for treating mental health conditions, not as a sole solution for weight loss.
- Potential Side Effects: Be aware of potential side effects, such as anxiety, jitteriness, or insomnia.
- Blood Pressure Monitoring: During Wellbutrin treatment, it’s important to be vigilant about potential increases in blood pressure, and therefore blood pressure should be monitored regularly.
- Pregnancy and Breastfeeding: Patients who are pregnant, planning to become pregnant, or who are breastfeeding, should discuss the risks of taking Wellbutrin with their healthcare provider.
- History of Eating Disorders: If you have a history of eating disorders or severe weight-related health issues, you may need to exercise caution before using Wellbutrin for weight loss.
What to Do If Wellbutrin Isn't Working
If you're not seeing the desired results with Wellbutrin, here are some steps you can take:
- Be Patient: It can take several weeks to months to settle on the right dose of Wellbutrin for your medical condition.
- Track Your Symptoms: Throughout the process of finding the right dose of medication, your healthcare provider will have you track your symptoms and any side effects.
- Attend Follow-Up Appointments: It is important to attend all your follow-up appointments, even if you’re feeling relief from your symptoms right away.
- Talk to Your Doctor: Talk to your provider about what the most effective dosage for you is. You may need to adjust your dosage over time to ensure the effectiveness of your treatment and the minimization of unwanted side effects.
Alternatives to Wellbutrin for Weight Loss
If Wellbutrin is not effective or if you're looking for other options, there are alternative prescription medications that can assist with healthy weight loss initiatives. These include:
- Contrave: A medication that mixes bupropion with naltrexone, that also targets your brain to help reduce your feelings of hunger and lead to weight loss.
- Xenical: A prescription gastrointestinal lipase inhibitor. Its job is to stop lipase, an enzyme that breaks down fat, from doing its job. This can help stop fat from being absorbed, instead allowing it to pass directly through your body.
- Phentermine: Healthcare professionals might suggest a combination of phentermine and bupropion to aid in weight loss.
