Exxua XR Is a Prescription Antidepressant Used to Treat Major Depressive Disorder in Adults

Exxua XR (Gepirone extended-release) is a brand-name prescription medication approved by the FDA for the treatment of major depressive disorder (MDD) in adults. It's the first and only antidepressant in the azapirone class — a category that's chemically related to Buspirone (Buspar), which has been used for anxiety for decades. If you've recently heard about Exxua XR or your doctor has mentioned it, here's everything you need to know.

What Is Exxua XR?

The Basics

• Brand name: Exxua XR (also referred to as Exxua)
• Generic name: Gepirone (also known as Gepirone ER or Gepirone extended-release)
• Drug class: Azapirone antidepressant; selective 5-HT1A receptor partial agonist
• Manufacturer: Developed by Fabre-Kramer Pharmaceuticals; commercialized in the U.S. by Aytu BioPharma
• FDA approval: September 2023
• Commercial launch: January 20, 2026
• Controlled substance: No — Exxua XR is not a controlled substance
• Former names: Travivo, Ariza, Variza (names used during development)

Exxua XR has had a long road to market. It was FDA-approved in September 2023 but wasn't commercially available until Aytu BioPharma launched it nationwide in January 2026 — a gap of over two years. For more on that history, see our Exxua XR shortage and availability update.

What Is Exxua XR Used For?

Exxua XR is FDA-approved to treat major depressive disorder (MDD) in adults. MDD is more than just feeling sad — it's a clinical condition characterized by persistent depressed mood, loss of interest in activities, changes in sleep and appetite, fatigue, difficulty concentrating, and sometimes thoughts of self-harm.

While Exxua XR is only approved for depression, there is ongoing research into other potential uses, including generalized anxiety disorder and decreased libido. These are not approved uses, and Exxua XR should only be taken as prescribed by your doctor.

How Is Exxua XR Taken?

Exxua XR comes as extended-release tablets in four strengths:

• 18.2 mg
• 36.3 mg
• 54.5 mg
• 72.6 mg

Dosing Schedule

Your doctor will start you at the lowest dose and gradually increase it:

1. Days 1-3: 18.2 mg once daily
2. Day 4: May increase to 36.3 mg once daily
3. After Day 7: May increase to 54.5 mg once daily
4. After an additional week: May increase to 72.6 mg once daily (maximum dose)

Important Instructions

• Take with food — Exxua XR must be taken with a meal
• Same time each day — Pick a consistent time and stick to it
• Swallow whole — Do not break, crush, chew, or dissolve the tablets
• Don't stop suddenly — Talk to your doctor before discontinuing

Special Dosing

• Older adults (65+): Start at 18.2 mg, may increase to 36.3 mg after 7 days

Who Should Not Take Exxua XR?

Exxua XR is not right for everyone. You should not take it if you:

• Are allergic to Gepirone or any ingredients in Exxua XR
• Have congenital long QT syndrome or a baseline QTc interval greater than 450 milliseconds
• Have severe liver impairment (Child-Pugh C)
• Are taking strong CYP3A4 inhibitors (such as Ketoconazole, Itraconazole, Clarithromycin, Ritonavir, or Nefazodone)
• Are taking MAOIs, or have taken one within the past 14 days (including Linezolid and IV Methylene Blue)

Pregnancy and Breastfeeding

Exxua XR may harm an unborn baby. Taking it during the third trimester may cause withdrawal symptoms in the newborn. It's unknown whether Gepirone passes into breast milk. Talk to your doctor about the risks and benefits if you're pregnant, planning to become pregnant, or breastfeeding.

What Are the Side Effects?

The most common side effects of Exxua XR include:

• Dizziness
• Nausea
• Insomnia
• Abdominal pain
• Dyspepsia (indigestion)

Serious side effects include suicidal thoughts and behaviors (especially in patients under 25), QT prolongation, serotonin syndrome, and manic episodes. For a complete breakdown, see our detailed guide on Exxua XR side effects.

One notable advantage of Exxua XR is that it's less likely to cause sexual side effects and weight gain compared to SSRIs and SNRIs — a major reason many patients and doctors are interested in it.

How Much Does Exxua XR Cost?

As a brand-name medication with no generic available, Exxua XR is expensive:

• Cash price: Approximately $1,500 to $1,800 per month for 30 tablets (varies by strength; 72.6 mg runs about $1,787 for 30 tablets)
• Generic available: No. New chemical entity (NCE) exclusivity extends through September 2028.
• Insurance: Coverage varies. Many plans require prior authorization and/or step therapy (trying generic antidepressants first). Formulary coverage is expanding throughout 2026.

What Makes Exxua XR Different?

Exxua XR stands out from other antidepressants in several ways:

• Unique mechanism: It's a selective 5-HT1A receptor partial agonist — not an SSRI, SNRI, or atypical antidepressant. Learn more about how Exxua XR works.
• Lower sexual side effects: A major advantage over SSRIs like Sertraline, Escitalopram, and Fluoxetine
• Lower weight gain risk: Less likely to cause the weight gain associated with many antidepressants
• Not a controlled substance: Unlike some other newer options, Exxua XR has no abuse potential

Final Thoughts

Exxua XR is a genuinely new option for adults with major depressive disorder — the first azapirone antidepressant to reach the market. Its unique mechanism of action, lower risk of sexual side effects and weight gain, and non-controlled status make it an attractive choice for patients who haven't found the right fit with traditional antidepressants.

The main challenges in 2026 are availability and cost. Exxua XR is only available through a limited pharmacy network, and the retail price is steep without insurance or savings programs. But for the right patient, it may be worth the effort to access.
