How Much Does Losartan Cost in Oregon in 2026?

Oregon Cash-Pay Prices for Generic Losartan

Generic losartan costs about $10 per month across Oregon retail pharmacies in 2026, making it one of the least expensive antihypertensives available in the state. That figure represents a 30-day supply of losartan potassium tablets at standard doses (25 mg, 50 mg, or 100 mg).

The brand-name version, Cozaar (manufactured by Merck), carries a list price around $80 per month. Very few patients pay that amount. Generic losartan potassium has been available since 2010, and market competition among generic manufacturers has driven retail prices down dramatically. At Costco pharmacies in Portland, Bend, and Eugene, a 30-day supply of losartan 50 mg regularly prices below $6 without insurance. Fred Meyer and Walmart locations across the state offer comparable pricing through their $4 generic programs.

Price variation exists between pharmacies. A 2024 analysis published in the Journal of the American Pharmacists Association found that cash prices for the same generic drug could vary by 200% to 800% across pharmacies within a single ZIP code (1). Oregon is no exception. Checking prices at two or three pharmacies before filling a prescription, or using a discount tool, can save $5 to $10 per fill.

The combination tablet losartan-hydrochlorothiazide (losartan/HCTZ) costs slightly more. Expect $12 to $20 per month for the generic combination at Oregon pharmacies. This fixed-dose combination pairs losartan 50 mg or 100 mg with HCTZ 12.5 mg or 25 mg and is commonly prescribed when a single agent does not achieve blood pressure targets below 130/80 mmHg, the threshold recommended by the 2017 ACC/AHA hypertension guideline (2).

Oregon Medicaid (Oregon Health Plan) Coverage

Oregon Medicaid, administered through the Oregon Health Plan (OHP), covers losartan with prior authorization. The drug appears on the Oregon Health Authority's preferred drug list under angiotensin II receptor blockers (ARBs), though prior authorization requirements apply for certain clinical scenarios.

For most OHP members with a diagnosis of hypertension (ICD-10 I10), diabetic nephropathy, or heart failure, getting losartan approved is straightforward. The prior authorization typically requires documentation that the patient has a qualifying diagnosis and, in some cases, that an ACE inhibitor was tried first or is contraindicated. ACE inhibitor intolerance (most often cough, occurring in roughly 5% to 35% of patients per a systematic review in Annals of Internal Medicine) is an accepted reason for ARB use (3).

OHP members pay no copay for preferred generics. The Oregon Health Authority negotiates supplemental rebates with manufacturers through its contracted pharmacy benefit manager, which keeps ARB costs low for the program. If your prescriber submits the PA electronically, approval often comes back within 24 hours. Denials can be appealed through the OHP grievance process, and your prescriber's office can request an expedited review if clinically urgent.

One important detail: OHP coverage is managed through coordinated care organizations (CCOs) across the state. Each CCO may have slightly different formulary preferences. PacificSource Community Solutions, AllCare Health, and Columbia Pacific CCO all list generic losartan, but their PA criteria may differ. Ask your CCO's pharmacy helpline which specific documentation your prescriber needs to submit.

Commercial Insurance and Employer Plans in Oregon

Most commercial health insurers operating in Oregon place generic losartan on their lowest formulary tier. This is true across the state's major carriers.

Providence Health Plan, the largest insurer by enrollment in Oregon, lists losartan as a Tier 1 preferred generic. Copays range from $0 to $10 depending on the specific plan. Moda Health, Regence BlueCross BlueShield, Kaiser Permanente Northwest, and PacificSource Health Plans follow the same pattern. Losartan's status as an off-patent generic with multiple manufacturers means insurers have no financial reason to restrict access.

For patients on high-deductible health plans (HDHPs), losartan purchased before meeting the deductible still typically costs only $10 to $15 at the pharmacy counter. Some HDHPs classify preventive medications differently. Under IRS Notice 2019-45, certain chronic disease drugs, including antihypertensives, can be covered pre-deductible by HDHPs without affecting HSA eligibility (4). Check whether your employer's plan has adopted this provision.

Medicare Part D plans in Oregon also cover losartan. Under the Inflation Reduction Act provisions active in 2026, out-of-pocket prescription drug costs for Medicare beneficiaries are capped at $2,000 annually. For a drug costing $10 per month, most Medicare Part D enrollees pay a $0 to $5 copay and never approach that cap with losartan alone.

Discount Programs and Savings Cards

Even at $10 per month, options exist to pay less. Oregon patients without insurance, or those with high-deductible plans, can access several discount pathways.

GoodRx, RxSaver, and similar aggregators. These platforms compile pharmacy-specific discount prices. In May 2026, GoodRx lists losartan 50 mg (30 tablets) as low as $4.00 at select Oregon pharmacies, including Costco, Walmart, and some independent pharmacies. The coupons are free to use, require no insurance, and work at the pharmacy counter.

Walmart and Fred Meyer $4 generic programs. Both retailers include losartan on their $4/month generic lists. This applies to 25 mg, 50 mg, and 100 mg tablets. A 90-day supply costs $10 at Walmart. No coupon or membership is required.

Mark Cuban Cost Plus Drugs. This online pharmacy offers losartan 50 mg at a transparent markup over manufacturing cost. Prices run approximately $4 to $6 for a 30-day supply, plus a flat shipping fee. The pharmacy ships to Oregon addresses and requires a valid prescription.

Manufacturer savings cards. Merck previously offered copay assistance for brand-name Cozaar, but most savings card programs have shifted focus to newer, on-patent medications. For generic losartan, manufacturer coupons are largely unnecessary given the low baseline cost. If a prescriber writes for brand Cozaar specifically (rare in 2026), Merck's patient assistance programs may still apply for uninsured patients meeting income thresholds. Contact Merck's patient assistance line or visit their website for current eligibility.

Oregon Prescription Drug Program (OPDP). Oregon operates a state-sponsored discount card program open to all Oregon residents regardless of income or insurance status. The OPDP card provides negotiated discounts at participating pharmacies and can be used for losartan fills when the patient is paying cash.

Compounded Losartan in Oregon

Compounded losartan is available through licensed 503A compounding pharmacies in Oregon. This route exists primarily for patients who need a non-standard dosage form, such as a liquid suspension for those who cannot swallow tablets or a specific dose not commercially available.

Oregon follows federal 503A compounding rules under the Drug Quality and Security Act of 2013 (5). A 503A pharmacy compounds medications based on individual patient prescriptions. The prescriber must write a patient-specific prescription, and the pharmacy must hold a valid Oregon Board of Pharmacy license.

Compounding is legal and regulated. The Oregon Board of Pharmacy inspects 503A facilities and enforces USP 795/800 standards. Several compounding pharmacies operate in Portland, Salem, and Medford. Costs vary by pharmacy and formulation, but compounded losartan suspensions typically run $15 to $40 per month, higher than generic tablets due to the labor-intensive preparation.

For most patients, commercially available generic tablets are cheaper and more convenient. Compounding makes clinical sense in narrow situations: pediatric patients requiring weight-based liquid dosing, patients with dysphagia, or individuals with allergies to specific inactive ingredients (dyes, lactose) present in commercial tablets. The FDA's losartan label notes that a suspension can be prepared from tablets for pediatric use (6).

Why Losartan Remains a First-Line Option

Losartan earned its place in hypertension treatment through strong trial evidence. The LIFE trial (Losartan Intervention For Endpoint reduction in hypertension), published in The Lancet in 2002, randomized 9,193 patients with hypertension and left ventricular hypertrophy to losartan-based or atenolol-based therapy (7). Over a mean follow-up of 4.8 years, losartan reduced the primary composite endpoint of cardiovascular death, stroke, and myocardial infarction by 13% compared to atenolol (p=0.021). The stroke reduction was particularly striking: 25% lower risk with losartan.

"ARBs like losartan are a reasonable first-line choice for patients with hypertension, particularly those with left ventricular hypertrophy, diabetic nephropathy, or ACE inhibitor intolerance," according to the 2017 ACC/AHA/AAPA/ABC/ACPM/AGS/APhA/ASH/ASPC/NMA/PCNA Guideline for the Prevention, Detection, Evaluation, and Management of High Blood Pressure in Adults (2).

The RENAAL trial (Reduction of Endpoints in NIDDM with the Angiotensin II Antagonist Losartan) demonstrated that losartan 50 to 100 mg daily reduced the risk of doubling of serum creatinine by 25% and end-stage renal disease by 28% in patients with type 2 diabetes and nephropathy, compared to placebo on top of conventional therapy (8). That trial enrolled 1,513 patients and followed them for a mean of 3.4 years.

These outcomes, combined with the drug's now-generic pricing, explain why losartan remains among the most prescribed medications in the United States. IMS Health data estimates over 60 million losartan prescriptions dispensed nationally per year.

Telehealth Prescribing in Oregon

Oregon permits telehealth prescribing of losartan. The state's telehealth parity law (ORS 743A.058) requires insurers to cover telehealth-delivered services at the same rate as in-person visits, which includes evaluation and prescribing of antihypertensive medications.

A licensed Oregon prescriber (physician, nurse practitioner, or physician assistant) can evaluate a patient via video or audio visit, diagnose hypertension, and prescribe losartan without an in-person exam. The prescriber must hold an active Oregon medical license or be authorized through an interstate compact.

Several telehealth platforms operate in Oregon and prescribe losartan. HealthRX offers telehealth consultations with board-certified clinicians who can prescribe losartan and other antihypertensives, with prescriptions sent electronically to the patient's preferred Oregon pharmacy.

For telehealth-initiated losartan prescriptions, the prescriber should verify blood pressure readings. Many Oregon telehealth providers ask patients to use a validated home blood pressure monitor and submit readings before the visit. The American Heart Association recommends validated oscillometric upper-arm cuff devices for home monitoring (9).

Dr. Paul Whelton, lead author of the 2017 ACC/AHA hypertension guideline, has noted: "Home blood pressure monitoring is an essential component of hypertension management and can be effectively integrated with telehealth care delivery" (9).

How to Get the Lowest Losartan Price in Oregon

The cheapest route depends on your insurance status. Here is a quick breakdown.

If you have Oregon Medicaid (OHP): Your copay is $0 for generic losartan. Ensure your prescriber submits the prior authorization. If denied, request an appeal.

If you have commercial insurance: Fill at your plan's preferred pharmacy. Most plans set the copay at $0 to $10. If your copay exceeds $10, ask your pharmacist to run a GoodRx or RxSaver coupon instead of billing insurance. The cash-discount price may beat your copay.

If you are uninsured: Use a discount aggregator (GoodRx, RxSaver) or fill at Walmart, Costco, or Fred Meyer through their generic drug programs. Prices start around $4 for a 30-day supply.

If you need a 90-day supply: Walmart offers 90-day fills for $10. Mail-order pharmacies like Cost Plus Drugs and Amazon Pharmacy also offer competitive 90-day pricing with Oregon delivery.

If you need a non-tablet form: Contact a licensed 503A compounding pharmacy. Expect higher costs ($15 to $40 per month) but a formulation tailored to your needs.

The average Oregon resident taking losartan 50 mg daily spends between $48 and $120 per year out of pocket, depending on insurance status and pharmacy choice. At the low end ($4 per month at Walmart with a discount card), annual cost is $48 for blood pressure control backed by outcomes data from trials enrolling over 10,000 patients.
