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

Anastrozole (brand name Arimidex) is a medication that many postmenopausal women with hormone receptor-positive breast cancer take for 5 to 10 years. With such a long treatment duration, the cost of this medication really adds up — and for patients without optimal insurance coverage, the sticker price can be a shock. The good news: generic anastrozole is one of the most affordable cancer medications available, and with the right strategies, most patients can pay very little.

What Does Anastrozole Cost Without Insurance in 2026?

The retail cash price of anastrozole varies significantly by pharmacy. Without any discount, patients may see prices ranging from about $110 to $258 for a 30-day supply of 1 mg tablets, depending on the pharmacy. Some pharmacy websites show even higher retail prices. This price variation is partly due to how different pharmacy chains price their generic medications.

But here's the important fact: virtually no one needs to pay retail price. Pharmacy discount cards can reduce the cost to $5 to $13 for a 30-day supply — a reduction of 90% or more.

How to Use GoodRx to Save on Anastrozole

GoodRx is a pharmacy discount service that negotiates lower prices at retail pharmacies nationwide. For anastrozole, GoodRx currently shows prices as low as $5 per month at some pharmacies. To use it:

1. Go to GoodRx.com and search for "anastrozole 1 mg"
2. Enter your zip code to see prices at pharmacies near you
3. Print or save the coupon to your phone
4. Show the coupon to the pharmacist when you pick up — GoodRx discounts cannot be used with insurance (use one or the other)

Note: GoodRx coupons are reusable on every refill, and there's no membership fee required for the basic service.

SingleCare and Other Discount Cards

SingleCare is another popular pharmacy discount service. SingleCare shows prices for anastrozole as low as $13 for a 30-day supply at certain pharmacies. It's worth comparing both GoodRx and SingleCare prices at pharmacies near you, as the lower price can vary by location.

Other discount programs worth checking include RxSaver, Blink Health, and the NeedyMeds Drug Discount Card. Shopping around among these options can sometimes yield additional savings.

What Does Anastrozole Cost With Insurance?

For most patients with commercial insurance, generic anastrozole is covered as a Tier 1 or Tier 2 drug on formulary, meaning the typical copay is $10 to $30 for a 30-day supply. If you're paying more than this, it's worth calling your insurance company to ask:

• What tier is anastrozole on your formulary?
• Is a different generic manufacturer's version available at a lower tier?
• Does your plan offer lower pricing through a mail-order pharmacy?

Also compare your insurance copay to what you would pay with a GoodRx coupon — in some cases, the GoodRx cash price is lower than your insurance copay, especially at certain pharmacies.

Medicare Coverage for Anastrozole

Anastrozole is covered by most Medicare Part D and Medicare Advantage plans. The cost varies by plan and tier. Under Medicare Part D, the annual out-of-pocket maximum is $2,000 in 2025, and $2,100 in 2026 — once you hit this cap, your plan covers the full cost of covered medications. For patients with cancer taking multiple drugs, hitting the out-of-pocket maximum is common, after which anastrozole costs nothing for the rest of the year.

If you're in the Medicare donut hole (coverage gap), you're responsible for 25% of the drug's cost. For anastrozole, this can be approximately $30-$35 per month. Once you reach the catastrophic coverage threshold (approximately $3,300 out-of-pocket in 2025), your cost drops dramatically.

Patient Assistance Programs for Anastrozole

For patients who are uninsured or underinsured and cannot afford anastrozole even with discount cards, patient assistance programs are available:

• Good Days Patient Assistance Program: Call 1-877-968-7233 or visit mygooddays.org. You must have insurance and a valid prescription. Provides financial assistance with copays and other costs for eligible patients.
• NeedyMeds.org: Searchable database of patient assistance programs for anastrozole and thousands of other drugs. Includes both manufacturer and foundation-based programs.
• RxAssist.org: Another comprehensive resource for finding patient assistance programs, organized by drug name.
• Cost Plus Drugs (Mark Cuban): costplusdrugs.com offers transparent pricing for many generic drugs with significantly reduced markups. Worth checking for anastrozole pricing if you're paying cash.

Tips to Maximize Your Savings

• Get a 90-day supply — the per-dose cost is often lower, and fewer trips to the pharmacy
• Compare prices at 3-4 pharmacies using GoodRx before choosing where to fill — even within the same city, prices can vary by 50% or more
• Check if your insurance copay is lower than the GoodRx price — use whichever is cheaper (you cannot use both at once)
• During Medicare open enrollment, use Medicare.gov's plan finder to compare estimated out-of-pocket costs for anastrozole across different Part D plans

Bottom Line

Generic anastrozole is one of the most cost-reducible medications available. With a GoodRx or SingleCare discount card, most patients can pay as little as $5 to $13 per month regardless of insurance status. If you're paying more than $30/month, it's worth taking 10 minutes to explore the options above. And if finding it at a price you can afford means searching multiple pharmacies, medfinder.com can help you find which pharmacies near you have it in stock.
