Alternatives to Bupropion If You Can't Fill Your Prescription

When You Can't Fill Your Bupropion Prescription

Running out of your antidepressant is stressful — and when Bupropion is out of stock at pharmacy after pharmacy, that stress only gets worse. If you've been trying to find Bupropion and keep hitting dead ends, it may be time to talk to your doctor about alternatives.

Let's be clear: you should never stop taking an antidepressant abruptly without talking to your doctor. But if Bupropion simply isn't available and you need treatment now, there are other medications that may work for you.

In this article, we'll explain what Bupropion is, how it works, and walk through several real alternatives your doctor might consider.

What Is Bupropion?

Bupropion is an antidepressant classified as a norepinephrine-dopamine reuptake inhibitor (NDRI). It's sold under brand names including Wellbutrin, Wellbutrin SR, Wellbutrin XL, Zyban, Aplenzin, and Forfivo XL.

It's FDA-approved to treat:

• Major Depressive Disorder (MDD)
• Seasonal Affective Disorder (SAD)
• Smoking cessation (as Zyban)

Bupropion is popular because it's one of the few antidepressants that doesn't typically cause weight gain or sexual side effects — two of the most common reasons people stop taking other antidepressants like SSRIs.

How Does Bupropion Work?

Unlike most antidepressants, Bupropion does not primarily affect serotonin. Instead, it works by blocking the reuptake of two other neurotransmitters:

• Norepinephrine: Involved in alertness, energy, and concentration
• Dopamine: Involved in motivation, pleasure, and reward

By increasing the availability of these chemicals in the brain, Bupropion helps improve mood, energy, and focus. This unique mechanism is why it has a different side effect profile than SSRIs and SNRIs.

Alternatives to Bupropion

If you can't find Bupropion, your doctor may suggest one of the following alternatives. Each works differently, so the right choice depends on your specific symptoms, medical history, and treatment goals.

1. Vortioxetine (Trintellix)

What it is: Vortioxetine is an atypical antidepressant with multimodal serotonin activity. It's FDA-approved for Major Depressive Disorder.

How it compares to Bupropion: Like Bupropion, Trintellix has a lower rate of sexual side effects compared to traditional SSRIs. It may also help with cognitive symptoms of depression — such as difficulty concentrating and memory problems. However, it does affect serotonin (unlike Bupropion), so the mechanism is different.

Common side effects: Nausea (especially when starting), constipation, vomiting.

Cost: Brand-name Trintellix can be expensive ($400-$500/month without insurance), but manufacturer coupons may lower the cost significantly.

2. Mirtazapine (Remeron)

What it is: Mirtazapine is an atypical antidepressant classified as a noradrenergic and specific serotonergic antidepressant (NaSSA). It's FDA-approved for Major Depressive Disorder.

How it compares to Bupropion: Mirtazapine is a good option for patients who struggle with insomnia and poor appetite, as it tends to be sedating and can stimulate appetite. However, this means it may cause weight gain — which is the opposite of Bupropion's typical effect. It also has low rates of sexual side effects.

Common side effects: Drowsiness, increased appetite, weight gain, dry mouth.

Cost: Generic Mirtazapine is very affordable — typically $4 to $15 per month with a coupon.

3. Vilazodone (Viibryd)

What it is: Vilazodone is an SSRI with additional 5-HT1A partial agonist activity. It's FDA-approved for Major Depressive Disorder.

How it compares to Bupropion: Vilazodone may have a lower risk of sexual side effects and weight gain compared to traditional SSRIs like Sertraline or Paroxetine. However, it still works primarily on serotonin, which is a different mechanism than Bupropion.

Common side effects: Diarrhea, nausea, insomnia, dizziness.

Cost: Brand-name Viibryd can cost $300-$400/month without insurance. A generic version became available, bringing costs down to around $30-$80/month with a coupon.

4. Dextromethorphan/Bupropion (Auvelity)

What it is: Auvelity is a combination medication containing dextromethorphan and Bupropion. It was FDA-approved in 2022 as a rapid-acting antidepressant for Major Depressive Disorder.

How it compares to Bupropion: Auvelity actually contains Bupropion as one of its ingredients, so it shares some of the same benefits. The addition of dextromethorphan provides additional NMDA receptor antagonism, which may help it work faster than Bupropion alone. However, it's a brand-name medication with no generic available yet.

Common side effects: Dizziness, headache, diarrhea, nausea, drowsiness.

Cost: As a newer brand-name drug, Auvelity can cost $1,000+ per month without insurance. The manufacturer offers a savings program for eligible patients.

Important: Don't Switch on Your Own

These alternatives require a prescription and should only be started under your doctor's guidance. Never stop Bupropion abruptly — while it's less likely to cause withdrawal symptoms than SSRIs, sudden discontinuation can still cause mood changes and discomfort.

If you're having trouble finding Bupropion, contact your prescriber's office and explain the situation. They can help you transition safely to an alternative if needed.

Before You Switch: Try to Find Bupropion First

Before giving up on Bupropion entirely, it's worth making one more effort to locate it. Use Medfinder to check real-time pharmacy availability in your area. You can also try:

Final Thoughts

Bupropion is a unique and effective antidepressant, and there's no perfect one-to-one replacement. But if you truly can't find it, alternatives like Vortioxetine (Trintellix), Mirtazapine (Remeron), Vilazodone (Viibryd), and Auvelity are worth discussing with your doctor.

The most important thing is to not go without treatment. Depression is a serious condition, and consistent medication access matters. Whether you find Bupropion or switch to something else, keep working with your healthcare team to stay on track.
