How to Save Money on Entecavir in 2026: Coupons, Discounts, and Patient Assistance

Entecavir is one of the most cost-effective treatments for chronic hepatitis B when purchased with a discount card—but the retail price without any coupon or insurance can be staggering. Understanding your options can mean the difference between $1,100 and $11 per month for the same medication.

How Much Does Entecavir Cost Without Insurance?

The retail (cash) price of generic entecavir without any discount is approximately $1,126 for 30 tablets of the 0.5 mg dose. The 1 mg tablet is similarly priced. These are the sticker prices at major chain pharmacies before any coupon or insurance is applied.

The good news: virtually no one should pay retail price for entecavir. With the right discount card, generic entecavir is among the more affordable hepatitis B treatments available.

Option 1: GoodRx — Prices Starting at $13

GoodRx is the most widely recognized prescription discount platform. By presenting a GoodRx coupon at the pharmacy counter, patients can pay as little as $13–$31 for a 30-tablet supply of generic entecavir (0.5 mg) at major chains like CVS, Walgreens, Walmart, and Rite Aid. GoodRx Gold members may access even lower prices.

GoodRx works by negotiating rates with pharmacy benefit managers and passing the savings to customers. It is not insurance and can be used even without coverage. Prices vary by pharmacy and location, so always check your specific ZIP code.

Option 2: SingleCare — As Low as $11.06

SingleCare is another major discount card platform that reports prices as low as $11.06 for 30 tablets of generic entecavir 0.5 mg at pharmacies including Walmart, Kroger, Target, Walgreens, and Fry's. Comparing GoodRx and SingleCare prices for your specific pharmacy is always worthwhile—prices can vary significantly by location.

Option 3: Patient Assistance Programs

For patients who have insurance but still face high out-of-pocket costs, patient assistance programs (PAPs) may help bridge the gap:

• Good Days Patient Assistance Program: Available for patients with insurance and a qualifying chronic hepatitis B diagnosis. Contact Good Days at 1-877-968-7233 or mygooddays.org to apply.
• NeedyMeds and RxAssist: Directories of manufacturer and non-profit patient assistance programs. Search for entecavir at needymeds.org or rxassist.org to see current programs.
• State pharmaceutical assistance programs: Many states offer supplemental assistance for seniors and low-income patients on prescription drugs. Check your state's health department website for eligibility.

Option 4: Insurance Coverage for Entecavir

Most commercial health insurance plans cover entecavir, typically at Tier 2 or Tier 3. However, Medicare Part D places entecavir on Tier 4 (specialty tier), which means higher copays—ranging from $15 to $836 per fill depending on the plan and benefit phase.

If your Medicare copay is high:

• Compare your Part D copay to a GoodRx or SingleCare price — the discount card may actually be cheaper than your insurance copay
• During Medicare open enrollment (October 15–December 7), compare plans specifically on their entecavir coverage and tier placement
• Ask your prescriber to apply for a formulary exception if entecavir is on a high tier—Step therapy or prior authorization exceptions can reduce your tier copay

Option 5: Use Mail-Order for 90-Day Supply Savings

Most insurance plans offer a reduced per-tablet cost for 90-day mail-order fills compared to 30-day retail fills. If your plan covers entecavir via mail order, you can typically save 10–25% on your out-of-pocket copay simply by switching from a monthly retail fill to a quarterly mail-order fill.
