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

Exemestane (brand name Aromasin) is an important but often expensive breast cancer medication. Without insurance or a discount program, retail prices for a 30-day supply can exceed $500. The good news: there are multiple ways to bring that cost down dramatically — sometimes to less than $30 per month. This guide covers every option available in 2026.

How Much Does Exemestane Cost Without Insurance?

Without any insurance or discount program, the retail price of generic exemestane 25 mg (30 tablets) varies significantly by pharmacy:

• National average retail: approximately $528 for 30 tablets (SingleCare data)
• Drugs.com price guide: starting from approximately $37 for 30 tablets at some pharmacies
• GoodRx listed price: starting around $35 for 30 tablets at some locations

The wide range reflects how dramatically prices vary by pharmacy and negotiation. The key insight: the "retail" price is rarely what you actually have to pay.

Option 1: GoodRx — Often the Fastest Way to Save

GoodRx is a free coupon service that negotiates lower prices with pharmacies on your behalf. According to GoodRx data, generic exemestane is available for as low as approximately $25–$35 for a 30-day supply at participating pharmacies with a GoodRx coupon. GoodRx Companion (a paid membership) lists prices as low as approximately $25 for exemestane.

How to use GoodRx:

1. Go to GoodRx.com or download the GoodRx app
2. Search for "exemestane 25 mg"
3. Enter your ZIP code to see prices at pharmacies near you
4. Show the coupon (or have the pharmacist scan the QR code) when you pick up your prescription

Important: You cannot use GoodRx and insurance at the same time. Compare the GoodRx cash price against your insurance copay and use whichever is lower.

Option 2: SingleCare — Another Excellent Discount Option

SingleCare is another free discount card service that can bring exemestane down to approximately $29 for 30 tablets at participating pharmacies. Like GoodRx, it's accepted at major chains including CVS, Walgreens, Walmart, and Kroger. It cannot be combined with insurance — compare prices before choosing.

Option 3: Shop Around — Prices Vary Dramatically

Even without a coupon, cash prices for generic exemestane vary widely between pharmacies. Costco and Sam's Club pharmacies are often significantly cheaper than CVS or Walgreens. Check prices at:

• Costco Pharmacy (you don't need a membership to use the pharmacy)
• Walmart Pharmacy
• Mark Cuban's Cost Plus Drugs (if exemestane is listed on their site)

Option 4: Get a 90-Day Supply

Whether you're using insurance or a discount card, a 90-day supply is almost always cheaper per tablet than three 30-day fills. Mail-order pharmacies (CVS Caremark, Express Scripts, Optum Rx) typically offer 90-day supplies at 2x the 30-day price, effectively giving you one month free. Ask your oncologist to write your prescription for a 90-day quantity.

Option 5: Good Days Patient Assistance Program

The Good Days Patient Assistance Program helps patients who have insurance but are struggling with high out-of-pocket costs for exemestane. To see if you qualify:

• Call: 1-877-968-7233
• Website: mygooddays.org
• Requirement: You must have valid insurance and a valid prescription to qualify

Option 6: NeedyMeds and RxAssist

NeedyMeds.org and RxAssist.org are nonprofit databases that compile patient assistance programs for thousands of medications. Search for "exemestane" on either site to find current programs, eligibility criteria, and application instructions. These programs are especially useful for uninsured or underinsured patients.

What Does Exemestane Cost With Insurance?

Exemestane is generally covered by most commercial insurance plans and Medicare Part D. What you'll pay depends on your plan's formulary tier:

• Commercial insurance: Typically $0–$30 copay for generic exemestane when covered on formulary; may require prior authorization on some plans
• Medicare Part D: Copay approximately $0–$375 depending on your plan and formulary tier; the 2026 Part D out-of-pocket cap is $2,100
• Some Medicare plans cover exemestane with very low or zero copay; always compare plans during open enrollment if your exemestane costs are high

Quick Comparison: Exemestane vs. Anastrozole Cost

If your oncologist says anastrozole or letrozole are medically equivalent options for you, it's worth knowing that generic anastrozole typically costs under $10/month with GoodRx, and generic letrozole is similarly inexpensive. These are significantly cheaper than exemestane. However, don't switch without consulting your oncologist — exemestane may be prescribed for good clinical reasons in your case.

The Bottom Line

You don't have to pay retail price for exemestane. Between GoodRx, SingleCare, mail-order discounts, and patient assistance programs, most patients can bring their cost well below $50/month. And once you've found savings, you'll still need to find a pharmacy that has it — see our guide on how to find exemestane in stock near you.
