Wellbutrin vs. Lexapro: Similarities & Differences

Wellbutrin and Lexapro are antidepressants used to treat depression and other mental health conditions.

Read on to learn more about these two drugs, and resources for seeking mental health or addiction treatment if required.

What Is Wellbutrin? Is Wellbutrin an SSRI?

Wellbutrin is a medication used to treat depression. Its generic name is bupropion. Is bupropion an SSRI, then? Wellbutrin is not an SSRI (selective serotonin reuptake inhibitor)[1]. Instead, it belongs to a different class of antidepressants called NDRIs (norepinephrine-dopamine reuptake inhibitors)[2].

Wellbutrin works by changing the levels of certain chemicals in the brain, specifically norepinephrine and dopamine. These chemicals help control mood and emotions. By blocking the reuptake (or reabsorption) of these chemicals, Wellbutrin increases their levels in the brain, which can help improve mood and reduce symptoms of depression.

Wellbutrin comes in several forms and dosages:

  • IR (immediate-release): Taken multiple times a day.
  • SR (sustained-release): Taken twice a day.
  • XL (extended-release): Taken once a day.

The most common starting dose for Wellbutrin XL is 150mg once daily, which may be increased to 300 mg once daily.

Wellbutrin is approved to treat major depressive disorder and prevent seasonal affective disorder (seasonal depression). It’s also sometimes used off-label to help people quit smoking, treat ADHD, and manage depression in people with bipolar disorder.

What Is Lexapro? Is Lexapro an SSRI?

Lexapro is another medication used to treat depression and anxiety. Its generic name is escitalopram. Unlike Wellbutrin, Lexapro is an SSRI (selective serotonin reuptake inhibitor).

Lexapro works by increasing the levels of serotonin in the brain. Serotonin is a chemical that helps regulate mood, sleep, and emotions. By blocking the reuptake of serotonin, Lexapro makes more of this chemical available in the brain, which can help improve mood and reduce symptoms of depression and anxiety.

Lexapro comes in different forms and dosages:

  • Tablets: Available in 5 mg, 10mg, and 20mg doses.
  • Oral solution: Available in 1mg per milliliter (mg/mL). 

The typical starting dose for Lexapro is 10mg once daily, which can be increased to a maximum of 20mg per day if needed.

Lexapro is approved to treat major depressive disorder in adults and adolescents aged 12+. It is also approved to treat GAD (generalized anxiety disorder) in adults and children aged 7 and older. Additionally, Lexapro is sometimes used off-label to treat other conditions like OCD (obsessive-compulsive disorder), panic disorder, and PTSD (post-traumatic stress disorder).

Wellbutrin Versus Lexapro

Although both are effective, they work in different ways and have unique characteristics. Understanding the difference between Wellbutrin vs Lexapro can help you and your doctor decide which one is best for you.

Uses

Wellbutrin is mainly used to treat depression and to prevent seasonal depression. Wellbutrin can also be used off-label for several other conditions, including:

  • Smoking cessation: Helps people quit smoking.
  • ADHD: Manages symptoms of ADHD (attention deficit hyperactivity disorder)
  • Bipolar disorder: Helps manage depressive episodes in bipolar disorder.
  • Antidepressant-induced sexual dysfunction: Treats sexual side effects caused by other antidepressants.

Lexapro is used to treat depression in adults and adolescents aged 12+. It is also approved to treat GAD in adults and children aged 7+. Additionally, Lexapro is sometimes used off-label to treat other conditions, such as:

  • OCD: Manages symptoms of OCD.
  • Panic disorder: Helps reduce panic attacks.
  • PTSD: Treats symptoms of post-traumatic stress disorder.
  • PMDD (premenstrual dysphoric disorder): Alleviates severe PMS symptoms.

Side Effects

Both Wellbutrin and Lexapro are effective medications for treating depression [3], but they can cause side effects. Knowing what to expect can help you manage these effects better.

While Wellbutrin is effective for many people, it can cause side effects. Here are some of the most common ones:

  • Dry mouth: A feeling of dryness in the mouth, which can be uncomfortable. Staying hydrated by drinking plenty of water can help.
  • Sweating: Increased sweating can occur even without physical activity. Wearing breathable clothing and staying in a cool environment might reduce this symptom.
  • Headache: Mild to moderate headaches are common. Over-the-counter pain relievers can often help, but consult your doctor if headaches persist.
  • Nausea: Feeling like you need to throw up, which can be managed by eating small, frequent meals and avoiding rich, spicy foods.
  • Insomnia: Trouble sleeping or staying asleep. Taking Wellbutrin earlier in the day can sometimes help with this issue.
  • Dizziness: Feeling lightheaded or unsteady. Standing up slowly and avoiding sudden movements can help prevent dizziness.
  • Weight loss: Some people may lose weight while taking Wellbutrin. Monitoring your diet and maintaining a healthy eating routine is essential.

Lexapro can also cause side effects. Here are some of the most common ones:

  • Nausea: Feeling sick to your stomach, which might improve over time. Eating bland foods and taking Lexapro with food can help.
  • Dry mouth: A dry feeling in the mouth. Chewing sugar-free gum or sucking on sugar-free candies can stimulate saliva production.
  • Sweating: Increased sweating, similar to Wellbutrin. Wearing light clothing and staying cool can help manage this symptom.
  • Diarrhea: Loose or watery stools, which can be uncomfortable. Staying hydrated and eating a balanced diet can help.
  • Fatigue: Feeling unusually tired or weak. Ensuring you get enough rest and pacing your activities can help manage fatigue.
  • Decreased appetite: Not feeling as hungry as usual, which can lead to weight loss. Eating small, nutritious meals can help maintain your energy levels.
  • Sexual side effects: Problems with ejaculation, low sex drive, and trouble reaching orgasm. This can be distressing and discussing these issues with your doctor can lead to adjustments in treatment to help manage these side effects.

Serious side effects of Wellbutrin include:

  • Seizures: Wellbutrin can increase the risk of seizures, especially at higher doses or in people with certain medical conditions.
  • High blood pressure: Wellbutrin can cause an increase in blood pressure, so regular monitoring is necessary.
  • Mental health changes: Agitation, anxiety, and unusual thoughts or behaviors should be reported to a doctor immediately.
  • Allergic reactions: Severe allergic reactions like rash, itching, swelling, and difficulty breathing need immediate medical attention.

Serious side effects of Lexapro include:

  • Suicidal thoughts and behaviors: Lexapro carries a warning about an increased risk of suicidal thoughts and behaviors, particularly in young adults and adolescents.
  • Serotonin syndrome: A potentially life-threatening condition [4] caused by too much serotonin. Symptoms include confusion, fever, rapid heartbeat, and muscle rigidity.
  • Low sodium levels: Especially in older adults, Lexapro can cause low sodium levels, leading to headache, confusion, and weakness.
  • Abnormal heart rhythms: Lexapro can cause changes in heart rhythm, which can be serious for people with heart conditions.

Interactions

Wellbutrin can interact with several other medications, which can increase the risk of side effects or reduce its effectiveness. Some important interactions to be aware of include:

  • MAOIs: Using these with Wellbutrin can increase the risk of serious side effects.
  • Other antidepressants: Combining with SSRIs, SNRIs, or tricyclic antidepressants can raise the risk of side effects.
  • Anti-seizure medications: Medications like carbamazepine can lower the effectiveness of Wellbutrin.
  • Alcohol: Drinking alcohol can increase the risk of seizures while taking Wellbutrin.
  • Heart medications: Medications like beta-blockers can interact with Wellbutrin.

Lexapro also has several interactions to be mindful of:

  • Other SSRIs and SNRIs: Combining these can increase the risk of serotonin syndrome, a serious condition.
  • Blood thinners: Medications like warfarin can increase the risk of bleeding.
  • NSAIDs: These can also increase the risk of bleeding.
  • MAOIs: Using these with Lexapro can lead to serious side effects.
  • Migraine medications: Certain medications like triptans can interact with Lexapro.

Cost Effectiveness

Wellbutrin is available in both brand-name and generic forms. The generic form, bupropion, is usually much cheaper. Using discount coupons can make Wellbutrin even more affordable. The cost can vary based on the form (immediate-release, sustained-release, or extended-release) and the dosage. Generally, generic bupropion is a cost-effective option for treating depression.

Lexapro is also available as a brand-name and generic medication. The generic form, escitalopram, is less expensive than the brand-name version. The price can vary depending on the dosage and whether you’re buying tablets or an oral solution. Overall, generic escitalopram is an affordable option for many people.

Which Is More Effective?

Wellbutrin is effective in treating depression and preventing seasonal affective disorder. It can also help people quit smoking and manage ADHD. Many people find Wellbutrin helpful, especially if they have not had success with SSRIs or experience sexual side effects from other antidepressants.

Lexapro is effective in treating both depression and generalized anxiety disorder. It is often prescribed because it works well for many people and has a relatively low risk of side effects. Lexapro is also beneficial for treating other conditions like OCD, panic disorder, and PTSD. Lexapro may also improve mood and reduce anxiety.

When directly comparing Wellbutrin and Lexapro, studies have shown that both medications are effective for treating depression [5]. However, they work in different ways and may be better suited for different people. For example:

  • Wellbutrin: Might be better for people who want to avoid sexual side effects or are also trying to quit smoking.
  • Lexapro: Might be better for those who also have anxiety disorders or who haven’t had success with other SSRIs.

Ultimately, the choice between Wellbutrin and Lexapro should be made with the guidance of a healthcare provider. They can help determine which medication is best for your specific needs and medical history.

When to Avoid Lexapro

Avoid Lexapro if you have a history of serotonin syndrome, are taking MAOIs, or have untreated bipolar disorder. It is also not recommended for people with liver or kidney problems without careful monitoring. Pregnant or breastfeeding women should consult their doctor before taking Lexapro.

When to Avoid Wellbutrin

Avoid Wellbutrin if you have a seizure disorder, an eating disorder like bulimia or anorexia, or if you are suddenly stopping alcohol or sedatives. Wellbutrin is also not suitable for people with certain heart conditions or those who have had a recent head injury. Pregnant or breastfeeding women should discuss with their doctor before using Wellbutrin.

Can You Take Wellbutrin and Lexapro Together?

For those wondering “can you take Lexapro and Wellbutrin together?”, it is possible, but it must be done under the guidance of a doctor. Combining these medications can be beneficial for some people because they work in different ways to treat depression. Wellbutrin is an NDRI, while Lexapro is an SSRI. By targeting different neurotransmitters in the brain, the combination can provide a more balanced approach to managing depression. However, taking them together can increase the risk of side effects, so get regular check-ups and follow your doctor’s instructions carefully.

Why Do Doctors Prescribe Lexapro and Wellbutrin Together?

Doctors might prescribe Lexapro and Wellbutrin together for several reasons:

  • Enhanced effectiveness: Some people find that taking both medications provides better relief from depression symptoms than taking either one alone. The combination can address a broader range of symptoms by targeting different brain chemicals.
  • Reducing side effects: Wellbutrin can help counteract some of the common side effects of Lexapro, such as sexual dysfunction and weight gain. Lexapro is known to cause sexual side effects like low libido, problems with ejaculation, and trouble reaching orgasm. Wellbutrin, on the other hand, has a lower risk of these side effects and can even improve sexual function in some cases.
  • Boosting energy and motivation: Wellbutrin can increase energy levels and motivation, which can be beneficial for people who experience fatigue and low energy as part of their depression. Lexapro helps with mood and anxiety but might not provide the same energy-boosting effects.
  • Addressing anxiety: Lexapro is particularly effective at treating anxiety disorders in addition to depression. For those who have both conditions, adding Lexapro to Wellbutrin can provide more comprehensive treatment for their anxiety symptoms.
  • Preventing relapse: Combining medications can sometimes provide more robust protection against relapse of depression. By addressing different aspects of the condition, the combination can help maintain long-term stability.
  • Customized treatment: Every person responds differently to medications. Some people might not get enough relief from a single medication. Adding another can provide a more personalized and effective treatment plan.

While combining Wellbutrin and Lexapro can be helpful, it’s imperative to monitor for potential interactions and side effects. Switching from Lexapro to Wellbutrin, or combining the medications without medical supervision is inadvisable. Your doctor will adjust the dosages and keep track of your progress to ensure the treatment is working well for you. Regular follow-ups and open communication with your healthcare provider are key to safely and effectively managing your mental health with these medications.
