Qsymia is a once-daily capsule that combines phentermine with extended-release topiramate, made by VIVUS and approved by FDA in July 2012 for chronic weight management in adults and, later, in patients aged 12 and older. It sits in an odd spot in the 2026 market: far cheaper than the GLP-1 drugs that dominate the conversation, and priced in a way that rewards buying directly from the manufacturer rather than shopping around.
The pricing picture also shifted twice in the last year. VIVUS cut the Costco member price in October 2025 and then discontinued its retail savings card in July 2026, so a lot of the advice floating around online now points at a program that no longer exists. This guide covers every published Qsymia price as verified on VIVUS’s own pages, CMS acquisition-cost data, and FDA approval records on September 2, 2026.
What Does Qsymia Cost Without Insurance?
Program prices come from VIVUS’s own Qsymia and Qsymia Engage pages. Acquisition cost comes from the 2026 CMS National Average Drug Acquisition Cost file, effective August 19, 2026. Retail figures come from SingleCare’s live Qsymia page, updated September 2, 2026.
| Option | Low | Average | High |
|---|---|---|---|
| Qsymia Engage home delivery, 90-day prescription | $70/mo ($210 per 90 days) | $70/mo | $70/mo |
| Qsymia Engage home delivery, 30-day prescription | $89/mo | $89/mo | $89/mo |
| Costco Member Prescription Program, 30-day supply | under $99/mo | under $99/mo | under $99/mo |
| Generic phentermine/topiramate ER, CMS acquisition cost | $94.30 per 30 capsules | $96.50 per 30 capsules | $98.76 per 30 capsules |
| Brand Qsymia, retail cash with no program | $282.87 per 30 capsules | $282.87 per 30 capsules | $282.87 per 30 capsules |
The unusual thing about that table is that it inverts the normal brand-versus-generic story. The manufacturer’s own direct price is the cheapest number on the page.
The manufacturer’s home delivery price is the floor
VIVUS runs a cash-only mail pharmacy called Qsymia Engage, fulfilled through Medvantx. Its published pricing is $89 for all 30-day prescriptions and for the 6-week New Patient Packs and Titration Packs, and $210 for a 90-day prescription, which VIVUS markets as $70 a month or $2.33 a day. Standard shipping is free on 90-day web orders, and shipping and handling costs apply on everything else.
Two limits are worth knowing before you plan around the $70 figure. Ninety-day prescriptions are not permitted in every state, so your state may cap you at the $89 monthly tier. And because the program is cash only, nothing you spend there gets submitted to insurance or counted toward a deductible.
VIVUS also routes commercially insured patients through LifeLine Specialty Pharmacy, which runs a benefits check first and then falls back to the same $89 and $210 cash prices if the plan does not cover the drug. LifeLine is not available in Puerto Rico, Guam, or the US Virgin Islands.
The Costco member price
VIVUS announced in October 2025 that the Qsymia price through the Costco Member Prescription Program had been lowered to under $99 for all doses, effective October 1, 2025. The Qsymia savings page currently states $98 for a 30-day prescription for Costco members. Claims under Medicare, Medicaid, or private insurance are not eligible for the Costco program, so this is another cash-only lane.
That price is a few dollars above the manufacturer’s own mail price but it comes with same-day pickup instead of shipping, which is a fair trade if you are starting the drug this week.
The retail savings card is gone
If you find a page telling you to download a Qsymia Retail Pharmacy Savings Card, it is out of date. VIVUS’s own savings-card page states that the program was discontinued effective July 1, 2026 and that existing cards could be used at a pharmacy only until August 31, 2026. Both of those dates have now passed.
VIVUS now points retail shoppers to third-party coupon sites instead. That matters for budgeting, because coupon-card prices are not manufacturer prices: they move between pharmacies and, on the coupon sites themselves, between visits.
The generic exists, and it is not automatically cheaper
FDA approved the first generic phentermine hydrochloride and topiramate extended-release capsules under ANDA 204982 on June 25, 2024, followed by a second generic from Dr. Reddy’s under ANDA 208175 on June 12, 2025. Teva’s catalog lists all four strengths (3.75/23 mg, 7.5/46 mg, 11.25/69 mg, and 15/92 mg) as AB rated, meaning therapeutically equivalent to Qsymia.
Here is where it gets counterintuitive. The 2026 CMS NADAC file, effective August 19, 2026, prices generic phentermine/topiramate ER at $3.14342 per capsule for the 11.25/69 mg strength, $3.18459 for 15/92 mg, $3.23226 for 3.75/23 mg, and $3.29203 for 7.5/46 mg. That is what pharmacies pay, and it works out to roughly $94 to $99 for a 30-capsule bottle before any pharmacy margin or dispensing fee.
In other words, the pharmacy’s cost to acquire the generic is already higher than the $89 the brand manufacturer will sell you the brand for, and about 40% above the $70-per-month 90-day price. Generic substitution is usually the first move on a cash prescription. On this drug, price both before you decide.
For context on how far that sits from the raw ingredient cost: plain phentermine 37.5 mg tablets carry a NADAC of $0.07085 each in the same file, about $2.13 for 30 tablets. The extended-release topiramate half of the combination, and the formulation work behind it, is essentially the entire price. Our phentermine cost guide covers that cheaper standalone option.
What Drives the Price
Which door you buy through. The manufacturer’s mail pharmacy, Costco’s member program, and an ordinary retail counter produce prices of $70, $98, and $282.87 for the same month of medicine. Nothing else on this list moves the number as much.
Prescription length. A 90-day prescription drops the effective monthly price from $89 to $70 and adds free shipping, but 90-day fills are not permitted in every state.
Brand versus generic, in an unusual direction. Two generics are on the market, but their acquisition cost lands above the brand’s direct-to-patient price, so the generic is only the cheaper option at a pharmacy that prices close to cost or where a coupon card lands well.
Which coupon card and which visit. Discount-card prices for phentermine/topiramate ER on SingleCare’s pages ranged from roughly $63 to $75 for 30 capsules of the 7.5/46 mg strength across two reads on September 2, 2026, with materially different per-pharmacy tables each time. A single chain’s card price on a coupon site is not a stable published figure, so use those pages to gauge the spread, then confirm at the counter.
The REMS and monitoring around it. Qsymia is dispensed under a Risk Evaluation and Mitigation Strategy and requires pregnancy testing before and monthly during treatment for patients who can become pregnant. Those tests and the prescribing visits are separate line items from the drug itself.
Cash Price vs. Insurance
Weight-management drugs are among the most commonly excluded categories in commercial drug benefits, and Medicare Part D is barred by statute from covering drugs used only for weight loss. So a very large share of Qsymia patients are effectively cash payers whether or not they carry insurance.
That is precisely why VIVUS built cash-only lanes. Both the Qsymia Engage home delivery pharmacy and the Costco Member Prescription Program explicitly refuse to process insurance claims, which means the money you spend there does not count toward a deductible or out-of-pocket maximum.
The math still usually favors cash. On a plan with a $3,000 deductible that excludes weight-management drugs anyway, there is no insurance price to compare against. Even on a plan that covers it, a $70 to $89 monthly cash price is at or below a typical brand-tier copay, and paying cash avoids the prior-authorization paperwork entirely. If your plan does cover it and your copay is under $70, use the plan. Otherwise the direct price is your number. Our fair price checker is a quick way to sanity-check any quote you get.
How to Pay Less
-
Start with the manufacturer’s own pharmacy, not your usual store. The $89 monthly and $210 quarterly prices at Qsymia Engage are the lowest published figures for this drug, and they beat the pharmacy acquisition cost of the generic.
-
Ask your prescriber to write a 90-day prescription. That single change drops the effective price from $89 to $70 a month and makes shipping free. Confirm your state allows 90-day fills on a Schedule IV product first.
-
Price the Costco member lane if you want same-day pickup. Under $99 for a 30-day supply, cash only, no insurance claim. You do not need a membership to use a Costco pharmacy in many states, but the member price specifically requires one.
-
Check both coupon cards on the generic before you assume it is cheaper. Card prices for phentermine/topiramate ER can land in the $60s, which would beat the manufacturer price, or in the $190s, which would not. Our comparison of GoodRx vs. SingleCare walks through checking both on the same drug in about two minutes.
-
Get the prescribing and monitoring visits handled cheaply. Qsymia requires ongoing follow-up and, for some patients, monthly pregnancy testing. A free or sliding-scale clinic can cover that at little or no cost, and a cash-pay doctor visit typically runs $50 to $150.
-
Compare against the rest of the weight-management shelf before committing. Contrave and phentermine are the other oral options, and the GLP-1s start at $149 a month for the Wegovy pill, with the full field priced in our GLP-1 cost guide. If a clinic or lab bill from the workup catches you off guard, our guide to negotiating medical bills covers what to say.
The Bottom Line
Budget $70 a month if you can get a 90-day prescription through Qsymia Engage, $89 a month if you fill 30 days at a time through the same program, and under $99 a month if you would rather pick it up at a Costco pharmacy. Those are VIVUS’s own published cash prices as of September 2026.
The two things that cost people money on this drug are both avoidable. One is filling the brand at a retail counter with no program, where 30 capsules average $282.87. The other is assuming the generic must be cheaper: at a 2026 CMS acquisition cost of $94 to $99 per bottle, it frequently is not.
