Key takeaways:

  • Lexapro (escitalopram) and Wellbutrin (bupropion) are two first-choice antidepressants. They’re similarly effective for treating depression, but they work in different ways.

  • Lexapro is a selective serotonin reuptake inhibitor (SSRI) that works by raising serotonin levels. Wellbutrin is an atypical antidepressant that works by increasing dopamine and norepinephrine levels. 

  • Wellbutrin is less likely to cause sexual side effects or weight gain compared to Lexapro. But each medication has unique side effects and interactions to consider when choosing between them.

Choosing the right antidepressant isn’t a one-size-fits-all decision. Your healthcare professional will make recommendations based on your symptoms, medical history, and preferences. But understanding more about your options can help you feel more informed and involved in the process.

Lexapro (escitalopram) and Wellbutrin (bupropion) are two popular options. Both are effective treatments. But they have unique dosage forms, side effects, and interactions that may make one a better fit for your needs than the other.

Whether you're just starting treatment or thinking about switching, GoodRx is here to help. We’ll break down Lexapro versus Wellbutrin to help you feel more confident in your next step.

Now, let’s take a closer look at six of these key differences between Lexapro versus Wellbutrin to help you decide which may be a better fit for your needs.

1. Lexapro and Wellbutrin work differently to treat depression

Lexapro and Wellbutrin treat depression in different ways.

Lexapro is a selective serotonin reuptake inhibitor (SSRI). Lexapro and other SSRIs raise serotonin levels in the brain. Serotonin is a chemical messenger that helps regulate your mood. Increased serotonin levels seem to improve depression and anxiety symptoms.

Wellbutrin is an atypical antidepressant. Unlike Lexapro, Wellbutrin doesn’t have much of an effect on serotonin levels. Instead, it’s thought to work by increasing the levels of norepinephrine and dopamine in the brain. Like serotonin, these chemicals help regulate your mood. This is why Wellbutrin is also referred to as a norepinephrine and dopamine reuptake inhibitor (NDRI).

2. Wellbutrin and Lexapro are considered similarly effective for depression

When it comes to Lexapro versus Wellbutrin, both medications are considered to be effective treatment options for depression.

A study with nearly 800 participants compared Lexapro to Wellbutrin for depression. Researchers found that both medications worked similarly well for improving depression symptoms. The main difference researchers found between these medications were their side effects — more on that later.

3. Lexapro and Wellbutrin come in different doses and dosage forms

Lexapro and Wellbutrin come in different doses and dosage forms. This may determine which medication is a better fit for you.

Lexapro and its generic come in 5 mg, 10 mg, and 20 mg tablets. The medication is also available as an oral solution that contains 5 mg per 5 mL. This is a helpful option for children or adults who have trouble swallowing tablets.

You’ll typically take Lexapro once a day. You can take it with or without food at whatever time of day works best for you.

Wellbutrin comes in a variety of dosage forms, including:

  • Immediate-release (IR) tablets: 75 mg, 100 mg

  • Sustained-release (SR) tablets: 100 mg, 150 mg, 200 mg

  • Extended-release (XL) tablets: 150 mg, 300 mg

  • As Forfivo XL: 450 mg

  • As Aplenzin: 174 mg, 348 mg, 522 mg

How often you take Wellbutrin depends on which form you’re taking. You’ll typically take IR tablets 2 to 4 times a day, SR tablets 1 to 2 times a day, and XL tablets once daily. The wider variety of dosage forms allows for more flexibility when it comes to taking Wellbutrin versus Lexapro.

4. Lexapro and Wellbutrin are approved for different health conditions

Lexapro and Wellbutrin are both FDA approved to treat depression. But they’re each approved for other conditions, too. Your prescriber may choose one medication over the other based on what condition you’re treating.

Lexapro is approved to treat depression in children and adults ages 12 and older. It’s also approved to treat anxiety in adults and children ages 7 and older. So Lexapro may be a better option if you’re living with anxiety as well as depression.

Wellbutrin is approved to treat depression in adults. Wellbutrin XL is also approved to treat seasonal affective disorder. And Zyban, an SR version of bupropion, is approved for smoking cessation. No forms of Wellbutrin are approved for children at this time, but sometimes a pediatrician will prescribe them off-label.

5. Lexapro and Wellbutrin have different side effects

Lexapro and Wellbutrin have some similar side effects, such as:

Both also have a boxed warning (the FDA’s most serious medication warning) for a higher risk of suicidal thoughts and behavior. This risk is higher for people under age 25.

But overall, people report fewer bothersome side effects with Wellbutrin than with Lexapro. This is particularly true when it comes to two common issues caused by antidepressants: sexual side effects and weight gain.

Wellbutrin is more likely to cause weight loss than weight gain. Lexapro may cause weight gain, but the risk is higher if you take it for 6 months or longer. Wellbutrin is also less likely to cause sexual side effects than Lexapro for most people.

Serious side effects

Lexapro and Wellbutrin also have rare, but serious side effects to consider. These may also help determine which option may be safer for you, based on your personal health history.

Rare, but serious Lexapro side effects include:

Rare, but serious Wellbutrin side effects include:

  • High blood pressure

  • Increased risk of seizures

6. Lexapro and Wellbutrin have different interactions to consider

Not only do their side effects differ, but Lexapro and Wellbutrin also interact with different medications (although there is some overlap).

Some notable Lexapro interactions include:

Common Wellbutrin interactions include:

  • MAOIs

  • Antiplatelet blood thinner medications, such as Plavix

  • Antiseizure medications, such as Tegretol (carbamazepine)

  • Antiviral medications, such as Norvir (ritonavir)

  • Other medications that raise the risk of seizures, such as amitriptyline

  • Medications that increase dopamine levels, such as Sinemet (carbidopa / levodopa)

  • Stimulants, such as Adderall

  • Alcohol

Keep in mind that the interactions we’ve listed above aren’t the only possible interactions with Lexapro and Wellbutrin. And in some cases, you can still take the interacting medications together. You may just need a dosage adjustment or additional monitoring. This is why it’s important to review your medication list with your prescriber and pharmacist when adding a new medication to your regimen. They can help determine if Lexapro or Wellbutrin is a better fit for you based on the other medications you’re taking.

Frequently asked questions

Yes, but only with a healthcare professional’s guidance. If your depression symptoms don’t improve with one medication, your prescriber may add another medication to help. Since Lexapro and Wellbutrin work in different ways, this combination may be an option. But it’s more common to switch to a different type of antidepressant medication before combining two treatments.

Yes, you can switch from Lexapro to Wellbutrin (or vice versa). But you should only do so with the guidance of a healthcare professional. In most cases, you’ll cross taper the two medications, meaning you’ll lower the dose of one while increasing the dose of the other. So this isn’t something you should try to do on your own.

Possibly, but the chance of gaining weight is higher with Lexapro than Wellbutrin. Many antidepressants can cause weight gain. But Wellbutrin is one of the least likely to do so, possibly because it actually has appetite suppressing effects. Lexapro is more likely to cause weight gain if you take it long term (6 months or longer). Talk to your prescriber if you have concerns about weight management while taking an antidepressant.

The bottom line

Lexapro (escitalopram) and Wellbutrin (bupropion) are both first-choice options for treating depression. But they work in different ways and come with different pros and cons.

Lexapro may be a better choice for treating anxiety along with depression. But Wellbutrin might be a good choice if you're concerned about sexual side effects or weight gain. Your prescriber can help you decide on Lexapro versus Wellbutrin based on your symptoms, health history, and any other medications you're taking.
