What Is Voquezna? Uses, Dosage, and What You Need to Know in 2026

Voquezna is a brand-name prescription medication you might have heard about as a newer alternative to drugs like omeprazole (Prilosec) or esomeprazole (Nexium). But what exactly is it, what does it treat, and is it right for you? This guide answers all the essential questions.

What Is Voquezna?

Voquezna is the brand name for vonoprazan, a first-in-class potassium-competitive acid blocker (PCAB) made by Phathom Pharmaceuticals. It reduces stomach acid by blocking the final step in acid production at the cellular level. It's the first medication of its class approved in the United States and represents the biggest innovation in acid-blocking drugs in over 30 years.

Voquezna is available as 10 mg and 20 mg oral tablets. It also comes in combination packs with antibiotics for treating H. pylori:

• Voquezna Triple Pak: Vonoprazan + amoxicillin + clarithromycin

• Voquezna Dual Pak: Vonoprazan + amoxicillin

What Is Voquezna Used For?

The FDA has approved Voquezna for the following uses in adults:

1. Healing of erosive esophagitis (all grades). Erosive esophagitis is when acid reflux damages the lining of your esophagus. Voquezna 20 mg taken once daily for 8 weeks heals this damage in most patients — at a rate slightly higher than the best traditional PPIs.

2. Maintenance of healed erosive esophagitis. After healing, Voquezna 10 mg once daily keeps the esophagus healed for up to 6 months.

3. Relief of heartburn from non-erosive GERD. If you have chronic heartburn but your esophagus isn't visibly damaged (non-erosive GERD), Voquezna 10 mg once daily for 4 weeks provides relief.

4. H. pylori eradication. Voquezna Triple Pak or Dual Pak taken for 14 consecutive days eradicates Helicobacter pylori bacteria, which can cause ulcers and gastritis.

How Do You Take Voquezna?

One major advantage of Voquezna over traditional PPIs: you can take it with or without food. PPIs typically work best when taken 30–60 minutes before eating because they require an active acid pump to work. Voquezna doesn't have this restriction.

• Erosive esophagitis healing: 20 mg once daily for 8 weeks

• Maintenance (after healing): 10 mg once daily for up to 6 months

• Non-erosive GERD: 10 mg once daily for 4 weeks

• H. pylori (Triple or Dual Pak): 20 mg twice daily plus antibiotics for 14 consecutive days

Swallow tablets whole. Do not crush or chew. Voquezna starts reducing stomach acid within 2–3 hours of the first dose.

Who Should NOT Take Voquezna?

Do not take Voquezna if you:

• Are allergic to vonoprazan or any ingredient in Voquezna

• Take rilpivirine-containing HIV medications (Edurant, Complera, Juluca, Odefsey) — this combination is contraindicated

• Are pregnant (especially avoid Triple Pak — clarithromycin may harm the fetus)

• Are breastfeeding (breastfeeding not recommended during treatment)

How Does Voquezna Compare to Omeprazole or Nexium?

Voquezna works differently than PPIs like omeprazole and esomeprazole (see our full guide on the mechanism). Key practical differences:

• Timing: Voquezna — take any time, with or without food. PPIs — work best 30–60 min before meals.

• Speed: Voquezna works within 2–3 hours. PPIs may take several days to reach full effect.

• Efficacy for severe disease: Voquezna has shown superior healing for Grade C/D erosive esophagitis vs. lansoprazole.

• Cost: Voquezna — brand only, ~$829–$1,013 cash/month. PPIs — generic available at $5–$30/month.

How Much Does Voquezna Cost?

Without insurance or assistance, Voquezna costs approximately $829–$1,013 per month (30-day supply) at most pharmacies. However:

• Voquezna Savings Card: as little as $25/month for commercially insured patients

• GoodRx: approximately $199

• Insurance (with commercial coverage + PA): ~$25–$50 copay

Where Can You Get Voquezna?

Voquezna is available at many pharmacies, but not all carry it consistently. Use medfinder.com to find which pharmacies near you have it in stock, or ask your prescriber to route the prescription through BlinkRx for home delivery.

The Bottom Line

Voquezna is a genuinely new type of acid blocker that can offer meaningful advantages for patients with severe or treatment-resistant GERD and erosive esophagitis. To understand how it works at a cellular level, see our explainer: How Does Voquezna Work?.
