Alternatives to Epclusa If You Can't Fill Your Prescription

Epclusa (sofosbuvir/velpatasvir) is one of the most effective treatments for hepatitis C, with an average cure rate of around 98%. But due to prior authorization delays, specialty pharmacy routing, or cost barriers, not every patient can access it immediately. The good news: several highly effective alternatives exist. Here's what you need to know about each option.

Always talk to your doctor before switching medications. The best alternative for you depends on your HCV genotype, liver health, prior treatment history, and current medications.

Why Epclusa May Not Be Immediately Available

As we detail in our guide on why Epclusa is hard to find, the main barriers include insurance prior authorization requirements, specialty pharmacy routing, and its $24,000+ list price per 28-day supply. If your prior authorization is denied or pending, discussing alternatives with your provider is a reasonable next step.

Alternative 1: Mavyret (Glecaprevir/Pibrentasvir)

Manufacturer: AbbVie

Treatment duration: 8 weeks for most treatment-naïve patients (12-16 weeks for some)

Genotypes covered: All 6 genotypes (pan-genotypic)

Cure rate: >95% across genotypes

Mavyret is often the most commonly prescribed alternative to Epclusa because it covers all 6 HCV genotypes and has a shorter 8-week treatment course for most treatment-naïve patients. Many insurers actually prefer Mavyret (it's less expensive for payers) and may require you to try it before approving Epclusa through step therapy.

Important caution: Mavyret is not recommended for patients with moderate-to-severe liver disease (decompensated cirrhosis, Child-Pugh B or C). For these patients, Epclusa (plus ribavirin) is the preferred option and your provider should make a strong case for it to your insurer.

Alternative 2: Harvoni (Ledipasvir/Sofosbuvir)

Manufacturer: Gilead Sciences

Treatment duration: 8–24 weeks depending on genotype and cirrhosis status

Genotypes covered: 1, 4, 5, and 6 (not genotypes 2 or 3)

Cure rate: 93–95%

Harvoni was approved in 2014 and remains widely used for genotype 1 (the most common in the US), 4, 5, and 6. Like Epclusa, it contains sofosbuvir as one of its two active ingredients. A generic version of Harvoni is available, which can reduce cost.

If you have genotype 2 or 3, Harvoni is not an option — talk to your provider about Epclusa or Mavyret instead.

Alternative 3: Vosevi (Sofosbuvir/Velpatasvir/Voxilaprevir)

Manufacturer: Gilead Sciences

Treatment duration: 12 weeks

Best for: Patients who have previously been treated with a DAA but still have HCV

Vosevi is a triple-drug combination that contains the same sofosbuvir/velpatasvir from Epclusa plus a third agent, voxilaprevir. It's approved for patients who have been treated with a previous DAA regimen that didn't achieve a cure. If you previously took Epclusa and it didn't fully clear your infection, Vosevi may be the next step.

Alternative 4: Zepatier (Elbasvir/Grazoprevir)

Manufacturer: Merck

Genotypes covered: 1 and 4 only

Zepatier is approved for genotypes 1 and 4 and can be a useful option for patients with kidney disease, since it doesn't require dose adjustment in renal impairment. It's less commonly used today given the broader genotypic coverage of Epclusa and Mavyret, but it remains an FDA-approved option.

Comparison Table: Epclusa vs. Alternatives

Epclusa: All genotypes | 12 weeks | ~98% cure | Works with decompensated cirrhosis (+ ribavirin)

Mavyret: All genotypes | 8–16 weeks | >95% cure | Not for decompensated cirrhosis

Harvoni: Genotypes 1, 4, 5, 6 | 8–24 weeks | 93–95% cure | Generic available

Vosevi: All genotypes | 12 weeks | For prior DAA failures | No generic

What to Tell Your Doctor

If you're having trouble accessing Epclusa, tell your provider exactly what the barrier is:

• "My insurance denied Epclusa" — ask about an appeal or Mavyret as an alternative
• "My pharmacy doesn't have it" — ask about specialty pharmacy options or ordering
• "I can't afford it" — ask about the Support Path program or authorized generic

Before switching medications, it's worth trying to locate Epclusa at other pharmacies. Check out our guide on how to find Epclusa in stock near you for step-by-step instructions.
