When it comes to addressing conditions like anxiety and depression, numerous medication options are available, each with unique benefits and considerations. Buspar (buspirone) and Wellbutrin (bupropion) are two commonly prescribed medications. This article explores the potential for weight loss associated with these medications, their effectiveness in treating anxiety, and the critical distinctions between them.
Understanding Buspar (Buspirone)
Buspar, the brand name for buspirone, is primarily prescribed to treat anxiety disorders, such as generalized anxiety disorder, in adults. It is an anxiolytic drug that works by modulating the levels of serotonin in the brain, creating a balancing effect that helps to alleviate anxiety symptoms. Buspirone is available as an oral tablet in strengths of 5 mg, 7.5 mg, 10 mg, 15 mg, and 30 mg, typically taken twice daily.
Buspar and Weight Gain
Generally, Buspar is not associated with significant weight gain and is considered weight-neutral for most users. This medication interacts with serotonin receptors in the brain, and weight changes are not a typical side effect.
Effectiveness and Onset of Action
Clinical trials suggest that Buspar can be an effective treatment for generalized anxiety disorder. It may be a suitable alternative to benzodiazepines due to its similar potential benefits and a lower risk of side effects and addiction.
You can expect to start noticing some effects of Buspar within 1 to 2 weeks, particularly in terms of anxiety relief. However, it might take about 4 to 6 weeks to experience the full benefits.

Potential Side Effects
Like all medications, Buspar can cause side effects, although not everyone experiences them. Common side effects include dizziness, headache, nervousness, sedation, drowsiness, excitement, and nausea. These side effects are usually mild and may subside as your body adjusts to the medication.
In rare cases, anger can be a side effect of buspirone. Symptoms of anger may include increased heart rate, tense muscles, clenching of the jaw, sweating, and feelings of anxiety. If you experience any of these symptoms, it's important to inform your doctor.
As with most drugs, some people can have an allergic reaction after taking buspirone. Symptoms of a mild allergic reaction can include skin rash, itchiness, and flushing. A more severe allergic reaction is rare but possible. Symptoms of a severe allergic reaction can include swelling under your skin, typically in your eyelids, lips, hands, or feet, swelling of your tongue, mouth, or throat, and trouble breathing. Call your doctor right away if you have an allergic reaction to buspirone, as the reaction could become severe.
Dosage and Administration
To treat anxiety disorders, the typical starting dose is 7.5 mg of buspirone taken by mouth twice per day, resulting in a daily dose of 15 mg. Your doctor may gradually increase your dose every 2 to 3 days by 5 mg per day to reach the optimal dose for you. The maximum recommended dose of buspirone is 60 mg per day, or 30 mg taken twice daily.
Interactions
Buspirone can interact with several other medications, including monoamine oxidase inhibitors (MAOIs), haloperidol, certain antidepressants, heart medications, antibiotics, antifungals, rifampin, dexamethasone, seizure medications, and ritonavir. It can also interact with grapefruit or grapefruit juice. It's essential to inform your doctor about all medications, herbs, and supplements you are taking to avoid potential interactions.

You should avoid consuming grapefruit or grapefruit juice during your treatment, as doing so can raise your risk for side effects from buspirone. Buspirone can be taken with or without food.
It’s best to avoid alcohol while taking Buspar, as alcohol can enhance the sedative effects of the medication, potentially leading to increased drowsiness or dizziness.
Delving into Wellbutrin (Bupropion)
Wellbutrin, known generically as bupropion, is an atypical antidepressant that works by affecting the levels of dopamine and norepinephrine in the brain. It is FDA-approved to treat depression and seasonal affective disorder and to aid in smoking cessation. It is also sometimes used off-label for conditions like ADHD and to counteract the sexual side effects of other antidepressants.
Wellbutrin and Weight Changes
Both Wellbutrin XL and Wellbutrin SR, different formulations of bupropion, may cause weight gain or weight loss, though weight loss is more commonly observed. Studies of Wellbutrin XL indicate that approximately 23% of individuals taking a daily dose of 150 to 300 mg experienced a weight loss of 5 pounds or more. Similarly, studies of Wellbutrin SR reveal that 14% of individuals taking a 300 mg daily dose lost more than 5 pounds, with 19% experiencing similar weight loss at a 400 mg dose.
Effectiveness and Uses
Wellbutrin is primarily used to treat depression and seasonal affective disorder. While it is not typically the first-line treatment for anxiety, it can be effective for generalized anxiety disorder, especially when co-occurring with major depression.

Potential Side Effects
Common side effects of Wellbutrin include rapid heart rate or increased blood pressure, insomnia, headache, agitation, dizziness, excessive sweating, weight loss, constipation, dry mouth, nausea, tremor, and tinnitus. Less commonly, Wellbutrin may increase the risk of seizures or suicidal thoughts and behavior.
Contraindications and Precautions
Bupropion is contraindicated in patients with a seizure disorder, bulimia or anorexia nervosa, or those undergoing abrupt discontinuation of alcohol, benzodiazepines, barbiturates, or antiepileptic drugs. Caution is advised in patients with conditions that increase the risk of seizure or who have other predisposing conditions.
Antidepressants, including bupropion, can increase the risk of suicidal thoughts and behavior in children, adolescents, and young adults in short-term trials. Patients of all ages treated with antidepressants should be monitored appropriately and observed closely for clinical worsening, suicidality, and unusual changes in behavior.
The use of buPROPion with alcohol may increase the risk of uncommon side effects such as seizures, hallucinations, delusions, paranoia, mood and behavioral changes, depression, suicidal thoughts, anxiety, and panic attacks.
Both buPROPion and caffeine can increase blood pressure.
Using buPROPion and nicotine together can cause an increase in blood pressure.
Dosage and Administration
Wellbutrin XL is an extended-release tablet taken once daily, while Wellbutrin SR is released faster and may require more frequent dosing.
Interactions
Using buPROPion with alcohol may increase the risk of uncommon side effects such as seizures, hallucinations, delusions, paranoia, mood and behavioral changes, depression, suicidal thoughts, anxiety, and panic attacks.
Both buPROPion and caffeine can increase blood pressure.
Using buPROPion and nicotine together can cause an increase in blood pressure.
Buspar vs. Wellbutrin: Key Differences
While both Buspar and Wellbutrin are sometimes used as second-line treatments for anxiety, they have several key differences:
- FDA-Approved Uses: Buspar is FDA-approved to treat anxiety disorders, while Wellbutrin is FDA-approved to treat depression and seasonal affective disorder.
- Mechanism of Action: Buspar primarily interacts with serotonin receptors in the brain, while Wellbutrin affects levels of norepinephrine and dopamine.
- Side Effects: Buspar's most common side effect is dizziness, while Wellbutrin's most common side effects include insomnia, headache, and agitation.
- Cost: Buspar (buspirone) is typically less expensive than Wellbutrin (bupropion).
Combining Buspar and Wellbutrin
In some cases, Buspar and Wellbutrin may be prescribed together, particularly when treating co-occurring depression and anxiety. However, it's crucial to be monitored for potential side effects, including an increased risk of seizures with higher doses of Wellbutrin.
Buspirone and Lipid Metabolism
Research suggests that buspirone may have a positive impact on lipid metabolism. Studies involving spontaneously hypertensive rats (SHRs) have shown that buspirone administration can lead to losses of body weight and abdominal fat weight through the activation of PPARδ-dependent catabolic metabolism, which produces energy. This process may contribute to the normalization of high blood pressure.
