What Is Wellbutrin (Bupropion)?

Wellbutrin is the brand name for bupropion, a prescription antidepressant that works by affecting neurotransmitters in the brain—primarily norepinephrine and dopamine. Unlike selective serotonin reuptake inhibitors (SSRIs), bupropion is a norepinephrine-dopamine reuptake inhibitor (NDRI). Because of this distinct mechanism, Wellbutrin is often chosen when patients have not responded well to SSRIs, have experienced unwanted sexual side effects on other antidepressants, or when low energy, cognitive slowing, or seasonal mood patterns are prominent. Bupropion is available in immediate-release (IR), sustained-release (SR), and extended-release (XL) tablets, allowing clinicians to tailor dosing to patient needs and minimize side effects such as insomnia.

In addition to its use in major depressive disorder (MDD) and seasonal affective disorder (SAD), another brand of bupropion (Zyban) is approved to help people stop smoking by reducing nicotine cravings and withdrawal symptoms. Aplenzin and Forfivo XL are other bupropion-containing products; because all of these contain bupropion, they should not be taken together.

Indications: When Wellbutrin Is Used

Wellbutrin (bupropion) is used to treat:

  • Major Depressive Disorder (MDD): To reduce depressive symptoms such as low mood, loss of interest, impaired concentration, fatigue, and sleep/appetite changes.
  • Seasonal Affective Disorder (SAD): Particularly to help prevent depressive episodes that emerge during fall and winter months.

Additional, FDA-approved indication for a bupropion brand:

  • Smoking Cessation (Zyban): Helps reduce cravings and withdrawal symptoms during smoking cessation efforts. May be used alone or with nicotine replacement therapy under medical supervision.

Common off-label uses (at a clinician’s discretion) include augmentation of other antidepressants, attention-deficit symptoms in adults, and bipolar depression in carefully selected patients with mood stabilizers on board. Off-label use should always be guided by a clinician who can weigh potential benefits and risks.

How Wellbutrin Works

Bupropion inhibits the reuptake of norepinephrine and dopamine, two neurotransmitters involved in motivation, alertness, attention, and mood regulation. It does not significantly increase serotonin levels, which partly explains its different side effect profile compared with SSRIs. By boosting norepinephrine and dopamine signaling, many patients experience improved energy, concentration, and drive, often without the sexual dysfunction or weight gain seen with some other antidepressants.

Onset of effect is typically gradual. Some people notice improvements in energy or concentration within 1–2 weeks, but full mood benefits can take 4–6 weeks or longer. Maintaining consistent daily dosing is important to achieve sustained benefits.

Formulations and Typical Dosing

Wellbutrin comes in several formulations. Do not change formulations without consulting your clinician, as release profiles and dosing schedules differ:

  • Immediate-Release (IR): Usually taken 2–3 times per day. Typical initial dose is 100 mg twice daily; may increase to 100 mg three times daily. Maximum total daily dose generally should not exceed 450 mg.
  • Sustained-Release (SR): Typically taken twice daily, about 8–12 hours apart. A common starting dose is 150 mg once daily for 3 days, then 150 mg twice daily if tolerated. Maximum total daily dose is typically 400 mg (200 mg twice daily).
  • Extended-Release (XL): Taken once daily in the morning. Typical starting dose is 150 mg once daily, which may increase to 300 mg once daily after several days to a week. Some patients may go up to 450 mg once daily if clinically justified and tolerated.

For SAD prophylaxis, clinicians often start bupropion XL in early fall and continue through spring. For smoking cessation with Zyban, typical dosing is 150 mg once daily for 3 days, then 150 mg twice daily; patients often pick a quit date 1–2 weeks after starting.

Always follow your healthcare provider’s instructions on dose and timing. Do not exceed recommended doses. The risk of seizures increases with higher doses and certain risk factors.

Instructions: How to Take Wellbutrin Safely

  • Take exactly as prescribed. Do not increase, skip, or stop doses without medical guidance.
  • With or without food: You can take Wellbutrin with food if you experience stomach upset, but food is not required for absorption.
  • Swallow SR and XL tablets whole. Do not cut, crush, or chew extended- or sustained-release tablets; doing so can release the drug too quickly and increase side effects, including seizure risk.
  • Timing matters. Because bupropion can be activating, morning dosing is preferred—especially for XL. Avoid taking doses near bedtime to reduce insomnia risk.
  • Missed dose: If you miss a dose, skip it if it’s late in the day and take your next dose at the regular time. Do not double up.
  • Do not abruptly discontinue. Stopping suddenly may cause symptom return or discomfort. Your clinician can guide a gradual dose reduction if needed.
  • Tablet shell in stool: With the XL formulation, you may sometimes see an inert tablet shell in your stool. This is normal and does not mean the medication didn’t work.
  • Drug testing: Bupropion may cause false positives on some urine drug screens. Inform the testing laboratory that you are taking bupropion.

Storage and Handling

  • Store at room temperature, away from moisture and heat.
  • Keep in the original container with the label intact.
  • Keep out of reach of children and pets.
  • Dispose of unused or expired tablets according to local guidelines or pharmacy take-back programs.

Who Should Not Take Wellbutrin (Contraindications)

Do not take Wellbutrin if you:

  • Have a seizure disorder or a history of seizures.
  • Are using any other bupropion-containing product (e.g., Zyban, Aplenzin, Forfivo XL).
  • Have an eating disorder such as anorexia nervosa or bulimia.
  • Are abruptly stopping alcohol, benzodiazepines, barbiturates, or other sedatives.
  • Have used an MAOI (monoamine oxidase inhibitor) in the past 14 days, including phenelzine (Nardil), tranylcypromine (Parnate), isocarboxazid (Marplan). Linezolid and IV methylene blue also pose significant interaction risks.
  • Are allergic to bupropion or any component of the formulation.

Before You Start: Tell Your Doctor

Share your full medical history and medication list, including prescriptions, over-the-counter drugs, vitamins, and herbal supplements. In particular, tell your clinician if you:

  • Have depression, anxiety, bipolar disorder, or a history of suicidal thoughts or attempts.
  • Have liver or kidney problems (dose adjustments may be needed).
  • Have had a head injury, brain tumor, or central nervous system disorder.
  • Have cardiovascular disease or high blood pressure.
  • Have glaucoma, especially narrow-angle glaucoma.
  • Have diabetes and use insulin or oral hypoglycemics.
  • Drink alcohol regularly or have a substance use disorder.
  • Are pregnant, planning pregnancy, or breastfeeding.

Important Safety Information

  • Activation and sleep: Bupropion can cause insomnia, restlessness, and mild anxiety in some patients, especially early in treatment. Morning dosing often helps. If you continue to have sleep trouble, ask about adjusting the timing or dose.
  • Seizure risk: The risk increases with higher doses and in those with certain medical conditions, eating disorders, abrupt sedative/alcohol withdrawal, or concomitant medications that lower seizure threshold. Never exceed prescribed doses.
  • Alcohol and sedatives: Avoid heavy alcohol use. If you drink alcohol or use sedatives regularly, do not stop abruptly without medical guidance, as withdrawal can increase seizure risk.
  • Other stimulants: Check before using decongestants (pseudoephedrine), stimulants, or weight-loss medications. Combining stimulatory agents can raise blood pressure, increase agitation, and heighten seizure risk.
  • Driving and machinery: Until you know how Wellbutrin affects you, use caution with driving or tasks requiring alertness.
  • Blood pressure: Bupropion can increase blood pressure. Periodic monitoring is advisable, particularly if you have hypertension or use nicotine replacement products.
  • Mood monitoring and suicidality: Antidepressants carry a boxed warning for increased risk of suicidal thoughts and behaviors in children, adolescents, and young adults. Monitor for worsening mood, irritability, agitation, anxiety, or unusual behavior changes, especially during the first months or during dose changes. Seek medical help promptly if concerning symptoms arise.
  • Mania/hypomania: In people with bipolar disorder, bupropion may precipitate a manic episode if not appropriately mood-stabilized. Screen for bipolar spectrum symptoms before starting.
  • Allergy and skin reactions: Stop and seek care for rash, hives, swelling, or signs of severe skin reactions.
  • Angle-closure glaucoma: Mydriasis can precipitate an acute attack in susceptible individuals. Seek urgent care for eye pain, vision changes, or redness.

Drug and Supplement Interactions

Bupropion is metabolized by CYP2B6 and is a strong inhibitor of CYP2D6. Interactions can increase side effects or reduce the effectiveness of other medications:

  • MAOIs: Contraindicated within 14 days due to risk of hypertensive crisis and serious interactions.
  • CYP2D6 substrates: Bupropion can raise levels of medications such as certain SSRIs (e.g., paroxetine, fluoxetine), TCAs (e.g., nortriptyline, desipramine), antipsychotics (e.g., risperidone), beta-blockers (e.g., metoprolol), Type 1C antiarrhythmics (e.g., propafenone), and tamoxifen. Clinical monitoring and dose adjustments may be needed.
  • CYP2B6 inhibitors/inducers: Drugs like ritonavir, efavirenz, clopidogrel, ticlopidine, cyclophosphamide, or carbamazepine can affect bupropion levels. Your prescriber may adjust dosing accordingly.
  • Other bupropion products: Do not combine with Zyban, Aplenzin, Forfivo XL, or any product containing bupropion.
  • Alcohol and sedatives: Increase seizure and adverse event risk, particularly with abrupt cessation.
  • Nicotine replacement therapy: Combined use can raise blood pressure; monitor closely when using nicotine patches or gum.
  • Stimulants and decongestants: May increase blood pressure, heart rate, or agitation; use only with clinician guidance.
  • Herbal supplements: St. John’s wort, yohimbine, and others with neuroactive or pressor effects may interact. Always disclose supplement use.

Common and Serious Side Effects

Many people tolerate Wellbutrin well, but side effects can occur. Common, usually transient effects include:

  • Dry mouth, headache, nausea, constipation
  • Insomnia, restlessness, anxiety, dizziness
  • Sweating, tremor, ringing in the ears
  • Reduced appetite, weight change (often weight loss)
  • Increased urination, stomach discomfort, taste changes

Seek medical attention promptly for serious or persistent symptoms, such as:

  • Seizures, fainting, severe headache or confusion
  • Worsening depression, suicidal thoughts or behavior, agitation, hallucinations, delusions
  • Chest pain, shortness of breath, fast or irregular heartbeat
  • Severe allergic reactions (rash, hives, swelling of face/lips/tongue, trouble breathing)
  • Severe skin reactions (red, swollen, blistered, or peeling skin)
  • Visual changes, eye pain (possible angle-closure glaucoma)
  • Menstrual changes, unusual bruising or swelling, jaundice (yellowing of skin/eyes), dark urine

This is not an exhaustive list. Always report unexpected or severe symptoms to your healthcare provider.

Pregnancy, Fertility, and Breastfeeding

  • Pregnancy: Data are mixed and do not conclusively show increased overall risk of birth defects, though some studies have noted signals that require individualized risk-benefit discussion. Untreated depression during pregnancy carries its own risks for parent and baby. Decisions should be personalized with your obstetric and mental health clinicians.
  • Breastfeeding: Bupropion passes into breast milk in low amounts. Case reports of infant irritability or seizures are rare. Discuss the benefits of treatment and potential risks with your clinician; monitoring the breastfed infant for feeding or sleep changes is prudent.
  • Fertility: No consistent evidence suggests impaired fertility with therapeutic use.

Special Populations and Dose Adjustments

  • Older adults: May be more sensitive to side effects; start low and titrate cautiously.
  • Liver impairment: Reduce dose and/or frequency in moderate-to-severe hepatic impairment.
  • Kidney impairment: Consider dose adjustments and monitor for accumulation of active metabolites.
  • Adolescents and young adults: Boxed warning for suicidality; close monitoring is essential.

Switching, Combining, and Discontinuation

  • Augmentation: Bupropion is commonly added to SSRIs or SNRIs to address residual symptoms (e.g., low energy, cognitive dulling) or to mitigate SSRI-associated sexual side effects. Combination strategies should be supervised to manage interaction risks.
  • Switching: When transitioning from another antidepressant, a cross-taper or washout may be needed depending on the agent. MAOIs require a 14-day washout.
  • Stopping treatment: If you and your clinician decide to stop Wellbutrin, a gradual taper may reduce the chance of symptom rebound and allow early detection of relapse.
  • Maintenance: For recurrent depression, maintenance therapy for 6–12 months after recovery (or longer for chronic/recurrent illness) is often recommended to reduce relapse risk.

What Makes Wellbutrin Different?

Because Wellbutrin targets norepinephrine and dopamine rather than serotonin, it has a distinctive clinical profile:

  • Less sexual dysfunction: Lower risk compared with many SSRIs/SNRIs. In some patients, bupropion improves sexual function.
  • Weight neutrality or modest weight loss: Particularly appealing if weight gain has been problematic with other agents.
  • Activating properties: Can improve energy, motivation, and concentration. For some, this manifests as restlessness or anxiety early in treatment; timing and dose adjustments usually help.
  • No significant serotonergic effects: Unlikely to cause serotonin syndrome alone but may interact with serotonergic agents indirectly through CYP2D6 inhibition.

Lifestyle Tips and Adherence

  • Pair medication with therapy: Cognitive-behavioral therapy, interpersonal therapy, and behavioral activation can boost outcomes and reduce relapse.
  • Structure your routine: Consistent sleep, physical activity, and nutrition support brain health and mood regulation.
  • Limit alcohol: Alcohol can worsen mood, impair sleep, and increase seizure risk with bupropion.
  • Set reminders: Dosing at the same time each morning aids adherence and minimizes insomnia.
  • Follow up: Regular check-ins allow dose optimization and early management of side effects.

Cost, Generics, and Access

Bupropion is widely available as a generic in IR, SR, and XL formulations, often at substantially lower cost than brand-name products. Prices vary by pharmacy, dose, and quantity. Patient assistance programs, pharmacy savings plans, and prescription discount services can reduce out-of-pocket costs. Discuss with your clinician and pharmacist which formulation best fits your clinical goals, daily routine, and budget.

When comparing prices online, prioritize safety and legality: choose licensed pharmacies that require valid prescriptions, provide pharmacist consultation, and protect your personal data. Avoid sources that offer prescription medications without verifying a prescription or medical evaluation.

Alcohol, Caffeine, and Everyday Interactions

  • Alcohol: Can increase seizure risk and worsen mood and sleep. If you drink, do so in moderation and avoid binges. Never stop heavy or chronic alcohol use abruptly without medical supervision.
  • Caffeine: High intake may worsen anxiety, tremor, or insomnia when combined with bupropion. Consider moderating caffeine if you feel jittery.
  • Nicotine: When used with nicotine replacement, blood pressure may rise. Monitor and report headaches or palpitations.
  • Decongestants: Pseudoephedrine and phenylephrine can raise blood pressure and increase nervousness; ask your clinician before use.

Realistic Expectations and Monitoring

Most antidepressants, including Wellbutrin, require consistent daily use and time to work. Expect incremental improvements week by week. Track changes in energy, motivation, concentration, and mood using a journal or rating scale. Share updates at follow-up visits so your clinician can fine-tune dosing or consider combination strategies if needed. If you experience worrisome side effects—particularly mood changes, suicidal thoughts, severe anxiety, or signs of allergic reactions—seek medical attention promptly.

Recap: Key Do’s and Don’ts

  • Do take Wellbutrin exactly as prescribed and at the same time each day.
  • Do swallow SR/XL tablets whole; never crush or chew.
  • Do monitor sleep, blood pressure, mood changes, and any unusual symptoms.
  • Do inform all your healthcare providers about your medications and supplements.
  • Don’t exceed recommended doses or combine with other bupropion-containing products.
  • Don’t abruptly stop alcohol, benzodiazepines, or other sedatives.
  • Don’t use with MAOIs or within 14 days of MAOI use.
  • Don’t ignore new or worsening mood symptoms—contact your clinician promptly.

Wellbutrin FAQ

What is Wellbutrin (bupropion) and how does it work?

Wellbutrin is an antidepressant that works as a norepinephrine–dopamine reuptake inhibitor (NDRI). By increasing norepinephrine and dopamine signaling, it can improve mood, energy, concentration, and motivation. It is also marketed as Zyban for smoking cessation.

What conditions is Wellbutrin prescribed for?

It’s FDA-approved for major depressive disorder (MDD), seasonal affective disorder (SAD), and as Zyban for smoking cessation. Off-label, clinicians may use it for adult ADHD, SSRI-induced sexual dysfunction, and fatigue in depression.

How long does Wellbutrin take to work?

Some people notice better energy, focus, or reduced cravings in 1–2 weeks, but full antidepressant effects often take 4–6 weeks. Smoking cessation benefits can appear within the first couple of weeks when started before a quit date.

What are the common side effects of Wellbutrin?

Common effects include insomnia, dry mouth, headache, nausea, constipation, tremor, anxiety or jitteriness, sweating, and increased heart rate or blood pressure. Taking doses earlier in the day and avoiding evening doses can reduce sleep problems.

What are the serious risks I should know about?

The main serious risk is seizures, which is dose-related and higher with predisposing factors (e.g., eating disorders, abrupt alcohol or benzodiazepine withdrawal, severe head trauma, certain medicines). There is also a boxed warning for increased risk of suicidal thoughts in young people. It can precipitate mania in bipolar disorder and rarely cause severe hypertension or allergic reactions.

Who should not take Wellbutrin?

People with a seizure disorder, current or prior bulimia or anorexia nervosa, or those using an MAO inhibitor (or within 14 days of one) should not take it. Caution is warranted in uncontrolled hypertension, bipolar disorder, abrupt cessation of alcohol/benzodiazepines, and with drugs that lower seizure threshold.

What formulations of bupropion exist and how do they differ?

There are immediate-release (IR), sustained-release (SR), and extended-release (XL) tablets. SR is usually taken twice daily; XL is once daily. XL tends to cause less insomnia and is simpler to take. Do not crush, split, or chew SR/XL tablets.

What is a typical Wellbutrin dosage?

For depression, XL often starts at 150 mg once daily, increasing to 300 mg daily after several days if tolerated. SR is commonly 150 mg once daily for 3 days, then 150 mg twice daily. The maximum recommended dose for most adults is 450 mg/day. Your clinician will individualize dosing.

When is the best time to take Wellbutrin?

Morning is best, especially with XL. If using SR twice daily, take the second dose mid-afternoon with at least 8 hours between doses to reduce insomnia risk.

Can Wellbutrin help with energy, focus, or ADHD?

Yes, its activating profile can improve energy and concentration. It is used off-label for adult ADHD, particularly when stimulants aren’t appropriate or when depression coexists. It may be less effective than stimulant medications for core ADHD symptoms.

Does Wellbutrin cause weight loss or weight gain?

It is generally weight-neutral to modestly weight-reducing. That contrasts with some antidepressants that cause weight gain. Individual responses vary.

How does Wellbutrin affect sexual function?

Compared with SSRIs/SNRIs, bupropion has a lower risk of sexual side effects and may improve libido or SSRI-related sexual dysfunction in some people.

What should I do if I miss a dose?

Skip the missed dose if it’s close to the next scheduled dose. Do not double up, as this can increase seizure risk. Resume your regular schedule.

Can I stop Wellbutrin abruptly?

Do not stop abruptly without medical guidance. While bupropion has a lower risk of discontinuation symptoms than serotonergic antidepressants, tapering is still recommended to prevent relapse and reduce side effects.

What important drug interactions should I know about?

Do not combine with MAO inhibitors, linezolid, or IV methylene blue. Bupropion is a strong CYP2D6 inhibitor and can raise levels of drugs like metoprolol, risperidone, paroxetine, and dextromethorphan, and may reduce tamoxifen’s effectiveness. Combining with other agents that lower seizure threshold (tramadol, antipsychotics, theophylline, systemic steroids) increases seizure risk. Alcohol can also raise seizure risk.

Can Wellbutrin be combined with an SSRI?

Yes, clinicians sometimes combine bupropion with an SSRI to boost antidepressant response or reduce SSRI-related sexual side effects and fatigue. The combination should be supervised due to interaction and blood pressure considerations.

Does Wellbutrin raise blood pressure?

It can elevate blood pressure and heart rate, especially at higher doses or in people with pre-existing hypertension. Monitor blood pressure periodically.

Is Wellbutrin the same as Zyban?

They contain the same active ingredient (bupropion) but are labeled for different indications. Zyban is the SR formulation labeled for smoking cessation with a specific dosing schedule around a quit date.

Is it safe to drink alcohol while taking Wellbutrin?

Alcohol can increase the risk of seizures and worsen mood or sleep. Limit or avoid alcohol while on bupropion. Heavy drinking, binge drinking, or abrupt alcohol withdrawal significantly raises seizure risk.

Can I take Wellbutrin after a night of heavy drinking?

No. Do not take bupropion during or immediately after a binge. Wait until you are hydrated, no longer intoxicated or withdrawing, and speak with your clinician about when to safely resume. Abrupt alcohol withdrawal combined with bupropion is particularly risky.

What about occasional or light alcohol use on Wellbutrin?

Some people tolerate small amounts, but even light drinking can contribute to insomnia or anxiety. If you choose to drink, keep it minimal and consistent, and discuss safe limits with your clinician.

Is Wellbutrin safe during pregnancy?

Data overall do not show a major increase in birth defects. A few studies suggested a small possible increase in certain cardiac defects, but findings are inconsistent and may be confounded. If you are planning pregnancy or become pregnant, discuss risks and benefits; untreated depression also carries risks.

Can I breastfeed while taking Wellbutrin?

Bupropion passes into breast milk in low amounts. Most infants tolerate it, but rare case reports describe possible seizures in partially breastfed infants. If used, monitor the baby for irritability, poor feeding, or unusual movements, and consider alternatives (e.g., sertraline) for newborns when feasible.

Should I stop Wellbutrin before surgery or anesthesia?

Many patients continue bupropion through surgery to avoid relapse. Inform your surgical and anesthesia teams. They may avoid anesthetic agents that lower seizure threshold (e.g., meperidine, high-dose tramadol). Do not stop abruptly without guidance.

Can I take Wellbutrin if I have a seizure history?

It is generally contraindicated in people with seizure disorders. If you have a past seizure or significant risk factors, your clinician will consider alternative treatments.

Is Wellbutrin safe if I have an eating disorder?

No. Bupropion is contraindicated in current or prior bulimia or anorexia nervosa due to a significantly increased seizure risk.

What if I have liver or kidney disease?

Impairment can increase bupropion and metabolite levels. Lower doses or less frequent dosing may be needed, especially in moderate-to-severe hepatic impairment or significant renal impairment. Your prescriber will individualize the plan.

What about using Wellbutrin around ECT?

Because bupropion lowers seizure threshold and can prolong seizures, many clinicians reduce the dose or hold it before and during electroconvulsive therapy. Coordination between your psychiatrist and ECT team is essential.

How does Wellbutrin compare to Zoloft (sertraline)?

Wellbutrin is activating, weight-neutral, and has fewer sexual side effects. Sertraline is often better for anxiety, OCD, and PTSD but more likely to cause GI upset and sexual dysfunction. Sertraline is serotonergic; bupropion is dopaminergic/noradrenergic.

Wellbutrin vs Lexapro (escitalopram): which is better?

For pure depression with fatigue, low motivation, or SSRI sexual side effects, bupropion may be preferred. For depression with prominent generalized anxiety, panic, or rumination, escitalopram often performs well. Escitalopram can cause sexual dysfunction and weight gain; bupropion has seizure and BP considerations.

Wellbutrin vs Prozac (fluoxetine): what are the key differences?

Fluoxetine has a long half-life, fewer withdrawal symptoms, and broad anxiety/OCD utility but more sexual side effects. Bupropion is more energizing, less sexual dysfunction, and may aid attention and smoking cessation. Both can be combined in select cases.

Wellbutrin vs Effexor (venlafaxine): how do they differ?

Venlafaxine targets serotonin and norepinephrine (dose-dependent), treats anxiety and some pain syndromes, but is associated with blood pressure increases and challenging discontinuation. Bupropion also can raise BP but typically has easier discontinuation and fewer sexual side effects; it’s less effective for anxiety.

Wellbutrin vs Cymbalta (duloxetine): which to choose?

Duloxetine is effective for depression and pain conditions (neuropathy, fibromyalgia). It may cause nausea, sweating, and sexual dysfunction. Bupropion is better for low energy and concentration, with lower sexual side effects, but doesn’t treat pain.

Wellbutrin vs mirtazapine: how do they contrast?

They have opposite profiles. Bupropion is activating and may decrease appetite/weight. Mirtazapine is sedating at lower doses, can increase appetite and weight, and helps insomnia and anxiety. Combining them (“California rocket fuel”) is sometimes used in resistant depression.

Wellbutrin vs vortioxetine (Trintellix): what’s the difference?

Vortioxetine is serotonergic with potential cognitive benefits and a low rate of sexual side effects compared with SSRIs, but it can cause nausea and is often higher cost. Bupropion is generally more activating, cheaper generically, and has minimal sexual side effects.

Wellbutrin vs vilazodone (Viibryd): which fits better?

Vilazodone is an SSRI/5-HT1A partial agonist that may cause less sexual dysfunction than traditional SSRIs but commonly causes GI upset. Bupropion is a non-serotonergic option helpful for low energy and SSRI sexual side effects, but with seizure risk considerations.

Wellbutrin vs trazodone: when to use each?

Trazodone is often used at low doses for insomnia and can cause daytime sedation and orthostasis. As an antidepressant, it requires higher doses with more side effects. Bupropion is usually better for daytime mood, energy, and cognition; trazodone can be added at night for sleep when appropriate.

Wellbutrin vs sertraline for postpartum depression: what matters?

Breastfeeding considerations often favor sertraline due to strong lactation safety data. Bupropion may be considered when sexual side effects or fatigue are limiting, but caution is advised in breastfeeding due to limited data and rare infant case reports.

Wellbutrin vs atomoxetine for adult ADHD: how do they compare?

Atomoxetine is FDA-approved for ADHD, targets norepinephrine, and lacks abuse potential; onset may take several weeks. Bupropion is off-label for ADHD, often helpful when depression coexists, and may be less effective than stimulants; it carries seizure risk and CYP2D6 inhibition.

Wellbutrin vs varenicline for quitting smoking: which is better?

Varenicline generally shows higher quit rates than bupropion. Bupropion can still be effective, especially when combined with nicotine replacement. Choice depends on prior response, side effects, comorbid depression, and cost/access.

Wellbutrin SR vs Wellbutrin XL: which formulation should I choose?

Both deliver bupropion; SR is usually taken twice daily, XL once daily. XL may cause less insomnia and is more convenient. SR is used for smoking cessation (as Zyban) and can be useful when dose flexibility is needed.

Wellbutrin vs SNRIs for anxiety: what’s the difference?

SNRIs (venlafaxine, duloxetine) treat both depression and many anxiety disorders. Bupropion may worsen anxiety in some people early on and isn’t a first-line anxiolytic, though it can help in depression with prominent fatigue and concentration problems.

Wellbutrin vs combination therapy with an SSRI: when to combine?

If there’s a partial SSRI response with fatigue, sexual dysfunction, or cognitive slowing, adding bupropion can boost remission rates and reduce sexual side effects. Combination requires monitoring for blood pressure changes and drug interactions.
