Wellbutrin vs. Lexapro: Similarities & Differences

Wellbutrin and Lexapro are two commonly prescribed medications used to treat depression and certain anxiety disorders. Yet, they differ significantly in how they work and the benefits they offer. Wellbutrin (bupropion) acts on dopamine and norepinephrine in the brain, often helping to alleviate symptoms of low energy and motivation. In contrast, Lexapro (escitalopram) is an SSRI that primarily boosts serotonin levels, making it effective for persistent sadness, worry, and emotional imbalance. 

While both aim to stabilize mood and improve quality of life, their mechanisms, side effects, and even additional uses vary. Understanding these similarities and differences is crucial for patients and clinicians to make informed decisions about their care. This article compares Wellbutrin and Lexapro in their management of mental health conditions.

What Is Wellbutrin? Is Wellbutrin an SSRI?

Wellbutrin is the name brand for the prescription medication bupropion, which is used to treat major depressive disorder (MDD) and seasonal affective disorder (SAD) [1]. Unlike most other antidepressants, Wellbutrin is not an SSRI. Rather, it is an example of a norepinephrine-dopamine reuptake inhibitor, or NDRI. This means that it acts as a monoamine agent, increasing the levels of dopamine and norepinephrine in the brain.

This mechanism of action makes Wellbutrin a preferred option for those patients with fatigue or lack of drive, symptoms that can be residual features of standard SSRIs. Also, it is generally less likely to be associated with sexual side effects or weight gain, both of which are common worries regarding SSRIs. Bupropion is also sold as Zyban for cessation of smoking. This unique profile can render it a valuable treatment for depression under circumstances where traditional serotonin-based therapies would not be preferred.

What Is Lexapro? Is Lexapro an SSRI?

Lexapro, the brand name of the drug escitalopram, is indicated for use in adults as well as children and adolescents aged 12 years and older [2]. The medication is approved for the treatment of generalized anxiety disorder (GAD; persistent worry and tension that interferes with functioning and has been present for 6 months or longer) in adults, adolescents, and children aged 7 years and older.

It is part of a group of drugs called selective serotonin reuptake inhibitors, or SSRIs. SSRIs are a class of medications that function by increasing the amount of serotonin, a neurotransmitter involved in mood regulation, in the brain. Lexapro prevents the reuptake of serotonin by the nerves, ensuring a higher and more constant level of mood and reducing depression and anxiety.

Lexapro is frequently chosen due to its more tolerable side effect profile and effectiveness at lower doses. In addition, many patients tolerate it better than other antidepressants. Lexapro isn’t used for other conditions because it directly works on serotonin. In short, Lexapro is an SSRI and is meant to help maintain emotional balance by decreasing chronic feelings of sadness and anxious thinking.

Wellbutrin Versus Lexapro

Wellbutrin and Lexapro are both effective antidepressants, but they work in different ways. Wellbutrin, a norepinephrine-dopamine reuptake inhibitor (NDRI), increases the levels of dopamine and norepinephrine, which can help alleviate symptoms of low energy and motivation. Lexapro is an SSRI, which means its primary function is to raise serotonin levels to combat chronic feelings of sadness and anxiety.

Moreover, Wellbutrin generally has less of a profile of sexual side effects and may help with smoking cessation, while Lexapro is frequently indicated for generalized anxiety. Deciding between the two will depend on one’s own specific symptoms, concerns about side effects, and personal preference for treatment. It should always be done in consultation with a competent physician.

Lexapro vs. Wellbutrin Uses

Lexapro and Wellbutrin are both antidepressants, although they are slightly different because they function differently in the brain. Lexapro, or escitalopram, is an SSRI indicated for the treatment of major depressive disorder (MDD) and generalized anxiety disorder (GAD). Escitalopram has been recently FDA approved for the indication of generalized anxiety disorder in adults and children ages seven and older [3]. Plus, it acts to decrease chronic feelings of sadness, nervousness, and emotional instability.

Conversely, Wellbutrin or bupropion is an NDRI that acts on dopamine and norepinephrine. It is primarily indicated for MDD and SAD, but is also FDA-approved for use as an aid in smoking cessation as Zyban. Wellbutrin is frequently selected for those patients who present with low energy, poor concentration, or who wish to avoid the common sexual side effects of SSRIs. The American Society of Addiction Medicine and the American Academy of Addiction Psychiatry Clinical Practice Guidelines for stimulant use disorder suggest that for patients with cocaine use disorder, clinicians may consider prescribing bupropion to support cocaine abstinence [1]. 

Lexapro vs. Wellbutrin Side Effects

Wellbutrin side effects

Like all medications, Wellbutrin comes with potential side effects. Some of the most common include:

• Dry mouth

• Nausea

• Insomnia

• Weight loss

• Headaches

• Dizziness

One significant benefit of Wellbutrin is that it has a low incidence of sexual side effects, including reduced libido or anorgasmia, which are common side effects of the SSRIs. Wellbutrin, though, is known to slightly elevate blood pressure and has a risk of inducing seizures, especially in those with a history of seizures or eating disorders. In some people, it can initially increase anxiety levels, although this often subsides with time.

Lexapro side effects

Lexapro, like other SSRIs, may lead to side effects such as

• Nausea

• Drowsiness

• Insomnia

• Dry mouth

• Increased sweating

• Weight gain

Sexual side effects, including reduced desire and delayed orgasm, are among the most common reasons patients report dissatisfaction with Lexapro. Additionally, Lexapro can rarely trigger serotonin syndrome, a serious condition linked to dangerously high serotonin levels, especially if combined with other serotonergic drugs. Always consult your doctor before changing or stopping treatment.

Lexapro vs. Wellbutrin Interactions

Recognizing the possibility of drug-drug interactions is important for effective and safe treatment. Both Lexapro and Wellbutrin raise different concerns. Escitalopram, though, is among the drugs whose coadministration with certain other drugs yields adverse effects, from the potential for serotonin syndrome or bleeding tendencies to QT prolongation. For example, concurrent use of escitalopram and rasagiline is to be avoided due to the risk of serotonin syndrome [3]. Also, SSRIs such as escitalopram are known to inhibit platelet functionality so that when prescribed with antiplatelet agents, low-molecular-weight heparin or NSAIDs, the risk of bleeding is elevated, particularly that of upper GI bleeding.

Plus, escitalopram coadministration with other agents, such as amiodarone, can increase the risk of QT prolongation, particularly in individuals with renal impairment. Meanwhile, Wellbutrin may raise seizure risk when combined with other drugs that lower seizure thresholds. Always inform your healthcare provider about all medications and supplements you are taking to ensure your therapy remains both safe and effective.

Lexapro vs. Wellbutrin Cost Effectiveness

Wellbutrin cost-effectiveness

Wellbutrin is available as both a brand-name drug and a generic (bupropion). The generic version is significantly more affordable, often costing just a fraction of the brand-name price. Costs vary based on dose and whether it’s the XL (extended-release) or SR (sustained-release) form. Without insurance, monthly expenses typically range from $15 to $50 for the generic. 

Many find Wellbutrin to be highly cost-effective, especially with widespread insurance coverage that often includes low co-pays. Additionally, discount cards, pharmacy coupons, and programs like GoodRx can further reduce costs, making it accessible even for those paying out of pocket.

Lexapro cost-effectiveness

Lexapro is also available as a generic (escitalopram), which greatly reduces its price compared to the brand version. Though sometimes slightly higher than bupropion, escitalopram typically costs under $100 monthly without insurance. 

Most health plans cover Lexapro, which helps offset the costs. Patients can also use pharmacy discount programs to save more. Ultimately, when comparing Lexapro vs. Wellbutrin, weighing cost alongside benefits, side effects, and personal health needs ensures a smarter, more sustainable treatment choice.

Which Is More Effective, Wellbutrin or Lexapro?

Wellbutrin (bupropion) and Lexapro (escitalopram) are both effective for treating major depressive disorder, but their benefits vary by individual needs. Clinical research, including NIH-supported studies, shows they offer similar rates of symptom improvement. Lexapro, an SSRI, is often better for depression with significant anxiety, while Wellbutrin, an NDRI, may be preferred for low energy, poor focus, or to minimize sexual side effects and weight gain. Neither is universally “more effective”; the best choice depends on a patient’s specific symptoms, side effect concerns, and health history. A healthcare provider can help determine the most appropriate option for personalized treatment.

When to Avoid Lexapro

Lexapro should be avoided in certain situations to ensure patient safety. It may not be suitable for individuals with a history of serotonin syndrome, bipolar disorder (due to the risk of triggering mania), or known QT prolongation, which can affect heart rhythm [2]. Caution is also needed if taking other medications that raise serotonin levels, such as other SSRIs, SNRIs, or migraine triptans, to avoid serotonin syndrome. 

People with uncontrolled seizures or severe liver impairment may also need alternative treatments. Always consult a healthcare provider before starting or stopping Lexapro to evaluate risks based on personal medical history and current medications.

When to Avoid Wellbutrin

Wellbutrin (bupropion) isn’t suitable for everyone. According to the U.S. National Library of Medicine, Wellbutrin should be avoided in people with a history of seizures, eating disorders like bulimia or anorexia nervosa, or those undergoing abrupt alcohol or sedative withdrawal [2]. It’s also generally avoided in patients taking monoamine oxidase inhibitors (MAOIs) or within 14 days of stopping one, due to the risk of hypertensive reactions. 

Wellbutrin can raise blood pressure, so caution is needed in uncontrolled hypertension. Additionally, individuals with bipolar disorder should use it carefully, as it may trigger manic episodes. Always discuss your complete health history with a healthcare provider to determine if Wellbutrin is a suitable option for you.

Can You Take Wellbutrin and Lexapro Together?

Yes, Wellbutrin (bupropion) and Lexapro (escitalopram) can be taken together, but only under close medical supervision. This combination is sometimes prescribed to enhance antidepressant effects by targeting different neurotransmitters: Lexapro boosts serotonin, while Wellbutrin affects dopamine and norepinephrine. However, using them together isn’t risk-free. Wellbutrin may increase the chance of seizures, and Lexapro can lengthen the QT interval, potentially affecting heart rhythm. Doctors carefully assess these risks, especially in people with heart conditions or a seizure history. 

Why Do Doctors Prescribe Lexapro and Wellbutrin Together?

Doctors often prescribe Lexapro (escitalopram) and Wellbutrin (bupropion) together to provide a more complete approach to treating depression or anxiety when a single medication doesn’t fully address all symptoms. Lexapro, an SSRI, primarily works by increasing serotonin levels, helping to stabilize mood and reduce persistent feelings of sadness or worry. Wellbutrin targets dopamine and norepinephrine, which can improve energy, motivation, and focus. 

By combining these two medications, physicians can address multiple aspects of depression at once, offering more balanced relief for patients who experience low mood, fatigue, and anxious thoughts. This approach may also help minimize common side effects, such as sexual dysfunction or weight changes, often linked to SSRIs alone. While this combination can be highly effective, it requires careful monitoring by a healthcare provider to ensure it’s both safe and tailored to a patient’s specific needs, thereby helping to achieve the best possible treatment outcome.

FAQs

Does Wellbutrin work better than Lexapro?

Wellbutrin and Lexapro are equally effective for depression, but their benefits vary by individual needs. Wellbutrin may be better for low energy and focus, while Lexapro often helps more with anxiety. Effectiveness depends on each person’s symptoms and how they tolerate side effects, so it is best to decide with a doctor’s guidance.

Can you switch from Lexapro to Wellbutrin?

Yes, many people switch from Lexapro to Wellbutrin, especially if they experience side effects like weight gain or sexual dysfunction. However, transitions should always be done gradually and under medical supervision to avoid withdrawal symptoms or relapse, ensuring the safest adjustment based on personal health history.

Is Wellbutrin more for anxiety or depression?

Wellbutrin is primarily prescribed for depression. Unlike SSRIs, it doesn’t directly target serotonin, so it’s generally less effective for generalized anxiety. However, it may help people with depression who also feel fatigued or unmotivated. Doctors typically prefer other treatments when anxiety is the primary concern.

Who is not a good candidate for Wellbutrin?

People with a history of seizures, eating disorders like bulimia or anorexia, or those undergoing sudden alcohol or sedative withdrawal should avoid Wellbutrin. It can lower the seizure threshold and raise health risks in these groups. A healthcare provider will review the medical history to determine if it’s safe.
