Save money on Adipex-P (Phentermine) in 2026. Compare prices, find coupons, discount cards, and patient assistance programs to lower your cost.
If you've been prescribed Adipex-P (Phentermine) for weight management, you might be wondering how much it's going to cost — and whether there are ways to bring that price down. The good news is that Phentermine is one of the most affordable prescription weight-loss medications available, especially if you know where to look for savings.
In this guide, we'll break down the actual cost of Adipex-P with and without insurance, the best discount programs, and patient assistance options for 2026.
Let's start with the sticker prices. Here's what you can expect to pay out of pocket in 2026:
The difference between brand and generic is dramatic. Brand-name Adipex-P can cost 10 times more than generic Phentermine — even though they contain the exact same active ingredient in the exact same dose.
Unless your doctor has specifically written your prescription for brand-only, always ask your pharmacist for generic Phentermine.
Prescription discount cards are the easiest way to lower your cost. They're free, require no insurance, and are accepted at most pharmacies nationwide. Here are the best options for Phentermine:
GoodRx consistently offers some of the lowest prices for generic Phentermine. With a free GoodRx coupon, you can typically pay $8-$12 for 30 tablets. GoodRx Gold members may pay as little as $1.80.
SingleCare shows generic Phentermine prices starting at around $9.91 for 30 tablets. It's free to use and accepted at over 35,000 pharmacies including CVS, Walgreens, and Walmart.
Several other programs offer competitive pricing on Phentermine:
Pro tip: Prices vary by pharmacy, so check multiple discount cards and compare prices at different pharmacy locations. The same medication can cost $5 at one pharmacy and $20 at another just a few miles away.
If you've seen mentions of an Adipex-P manufacturer savings card online, be aware that this program was discontinued on February 1, 2024. Teva Pharmaceuticals no longer offers a branded savings card for Adipex-P.
This is another reason to use generic Phentermine — it's cheaper than brand Adipex-P even was with the savings card.
If you have health insurance, here's what to know about Phentermine coverage:
If your insurance denies coverage, ask your doctor's office to submit a prior authorization. In many cases, documentation of BMI ≥30 (or ≥27 with comorbidities) is enough to get approval.
If you're uninsured or underinsured and struggling to afford your medication, these programs may help:
Teva Pharmaceuticals (the maker of Adipex-P) operates the Teva Cares Foundation Patient Assistance Program. This program provides certain Teva medications at no cost to eligible patients who:
Apply at tevacares.org or call their toll-free number for more information.
NeedyMeds (needymeds.org) is a nonprofit that maintains a database of patient assistance programs, state programs, and discount drug cards. Search for "Phentermine" to find current options.
RxAssist (rxassist.org) is a similar resource that connects patients with pharmaceutical company assistance programs. They list Teva's programs and other options that may apply.
Beyond coupons and assistance programs, here are additional strategies:
Adipex-P 37.5 mg tablets are scored, meaning they're designed to be split in half. If your doctor approves a lower dose (18.75 mg), you could split your tablets and effectively cut your cost in half. Do not split capsules — only scored tablets.
Lomaira is a lower-dose Phentermine taken three times daily. While it requires more pills, generic Phentermine 8 mg may be priced competitively and could be a good option if your doctor thinks a lower dose is appropriate. Read more about this option in our alternatives guide.
Pharmacy pricing for generic medications varies wildly. Walmart, Costco, and some independent pharmacies often have the lowest cash prices. Costco's pharmacy is open to non-members. Always compare at least 3-4 pharmacies before filling.
Beyond finding pharmacies with stock, Medfinder can help you identify pharmacies in your area that carry Phentermine, so you can compare prices and availability in one place.
Here's a summary of what you might pay for a 30-day supply of Phentermine 37.5 mg in 2026:
Adipex-P and generic Phentermine are among the most affordable weight-loss medications on the market. By switching to generic, using a free discount card, and shopping around at different pharmacies, most patients can fill a 30-day supply for under $10.
If cost is a barrier, look into the Teva Cares Foundation and other patient assistance programs. And if you're having trouble finding Phentermine in stock, check Medfinder for real-time pharmacy availability.
