How Much Does Lisinopril Cost Without Insurance in 2026?

Lisinopril is one of the most prescribed medications in the country, and the good news is it's also one of the cheapest. Here's what you can expect to pay, and how to find the lowest price near you.

What Lisinopril Actually Costs at the Pharmacy

Lisinopril is an ACE inhibitor used to treat high blood pressure, heart failure, and to protect kidney function in people with diabetes. It has been available as a generic since the early 2000s, and competition among manufacturers has driven the price down considerably. If you walk into a pharmacy today without insurance and ask to fill a 30-day supply of generic lisinopril, you can expect to pay anywhere from $4 to $40, depending on where you fill it, what dosage you need, and whether you use a discount card.

At the low end, large retailers like Walmart, Kroger, and Costco have long included lisinopril on their discount prescription lists. Walmart's well-known $4 generic program covers a 30-day supply of lisinopril in the most common dosages (10 mg, 20 mg, and 40 mg), and a 90-day supply runs just $10. These prices are available to anyone regardless of insurance status. Costco's pharmacy is similarly competitive, and you do not need a Costco membership to use their pharmacy in most states.

At the high end, if you walk into a chain pharmacy like CVS or Walgreens without a discount card and pay the cash price, you might see prices closer to $25 to $40 for a 30-day supply. The difference is not the medication itself but the pharmacy's retail markup. This is exactly the kind of gap that makes price comparison so important.

Generic Lisinopril vs. Brand Names: Prinivil and Zestril

Lisinopril was originally sold under the brand names Prinivil (manufactured by Merck) and Zestril (manufactured by AstraZeneca). Both brands are still technically available, but there is almost never a reason to use them. The generic version contains the identical active ingredient, in the same dosage, and is regulated by the FDA to meet the same standards for purity, potency, and bioavailability.

Brand-name Prinivil or Zestril can cost $100 to $300 or more for a 30-day supply. Since the generic works exactly the same way and costs a fraction of that, virtually all prescriptions are now filled with generic lisinopril. If your doctor writes a prescription for "Prinivil" or "Zestril," your pharmacist will almost always substitute the generic automatically unless the prescription specifically says "dispense as written." If you see a high price at the register, ask your pharmacist to confirm you are getting the generic version.

Where to Find the Lowest Price

The cheapest route for most people is one of the major retailer $4 programs. Walmart, Sam's Club, and several grocery store chains (Kroger, Meijer, Publix) offer lisinopril at $4 for a 30-day supply. These programs do not require insurance, a membership card, or any special enrollment. You simply present your prescription and ask for the $4 price.

If you do not have a retailer pharmacy nearby, free discount card programs from GoodRx, RxSaver, and similar services can bring prices at CVS, Walgreens, and Rite Aid down to the $7 to $15 range for a 30-day supply. These cards work like a coupon and are accepted at most pharmacies. Mark Cuban's Cost Plus Drugs also offers lisinopril at very low prices, typically around $4 to $5 for a 30-day supply plus a flat dispensing fee, with the medication shipped directly to you.

For those filling a 90-day supply, the savings multiply. Walmart charges $10 for 90 days, and many mail-order pharmacies offer similar pricing. If you take lisinopril daily (as most patients do), filling 90 days at a time is almost always the smarter financial move.

Insurance Tiers and Why Cash Might Be Cheaper

Here is something that surprises many people: even if you have insurance, your copay for lisinopril might be higher than the cash price. Many insurance plans place generic medications on Tier 1, with copays of $5 to $15. But if the $4 cash price at Walmart is lower than your Tier 1 copay, you are better off paying cash and not running it through insurance at all.

There is one caveat. If you are trying to meet your insurance deductible or out-of-pocket maximum, paying through insurance (even at a higher copay) counts toward those thresholds, while cash payments typically do not. For a medication this inexpensive, the difference is usually negligible, but it is worth considering if you have other expensive prescriptions.

How to Get the Best Deal on Lisinopril

Start by searching your medication on RxGator, where you can compare prices across multiple pharmacies and discount programs in one place. Prices for lisinopril vary significantly from one pharmacy to the next, and a two-minute search can save you $20 or more per month. Ask your doctor for a 90-day prescription if you are on a stable dose, since the per-day cost drops substantially with larger fills. And do not assume that your insurance copay is the best price available. For a medication as widely available and inexpensive as lisinopril, cash with a discount card often beats insurance.

Lisinopril is a medication where no one should be overpaying. It is one of the most affordable prescriptions on the market, and with the right pharmacy and a little comparison shopping, you can keep your monthly cost under $5.
