Overview
Qsymia combines phentermine, an appetite suppressant, with topiramate extended-release, and it occupies a specific and underappreciated place in the weight-management landscape. It is an FDA-approved oral medication — not a GLP-1, not compounded, and not expensive.
On efficacy, Qsymia is the strongest of the oral options. Clinical reporting describes it as producing the highest weight loss of any oral medication, at around 10%. That is materially less than semaglutide or tirzepatide achieve, but it is a real clinical result, and it comes without an injection and at a fraction of the cost.
Pricing is where Qsymia becomes genuinely interesting. The manufacturer programme advertises $70 a month, with that rate applying to 90-day prescriptions only, and notes that 90-day prescriptions are not available in all states. A separate home delivery pharmacy option is described at $89, and Costco members can pay $98 on a 30-day prescription — noting that the associated telehealth service can only offer 30-day prescriptions. A generic version became available in May 2025, with reported costs ranging from roughly $50 upward.
The reason Qsymia is not a universal answer is its safety profile. Topiramate carries meaningful contraindications and precautions — particularly regarding pregnancy, where it is associated with birth defects, and phentermine is a controlled substance with its own cardiovascular and psychiatric considerations. This is a medication that requires a real clinical conversation, not a menu selection. But for the right patient it delivers meaningful weight loss at roughly a tenth of what brand-name GLP-1s cost.
What Makes Qsymia Different
The Most Effective Oral Weight-Loss Medication
Clinical reporting describes Qsymia as producing around 10% weight loss, the highest of any oral weight-loss medication. Less than the injectable GLP-1s, but a genuine clinical result achieved with a capsule rather than a needle.
Dramatically Cheaper Than GLP-1 Therapy
At $70 a month on a 90-day prescription through the manufacturer programme, Qsymia costs roughly a tenth of brand-name GLP-1 list pricing. For patients priced out of GLP-1s entirely, that gap is the whole decision.
A Generic Has Been Available Since May 2025
A generic version of Qsymia became available in May 2025, with reported costs from around $50. Generic availability in this category is genuinely useful, and it puts effective pharmacotherapy within reach of patients for whom GLP-1s are simply unaffordable.
Contraindications That Require Real Attention
Topiramate is associated with birth defects and must not be used in pregnancy; phentermine is a controlled substance with cardiovascular and psychiatric considerations. This is a medication requiring a genuine clinical assessment, including a pregnancy plan for patients who could become pregnant.

Our #1 Recommended Provider
Qsymia is a genuinely useful option when GLP-1s are unaffordable or unsuitable. If GLP-1 therapy is accessible to you, the weight-loss difference is substantial — Coreage RX offers semaglutide and tirzepatide at a flat $99 per month.
Medications Offered
Brand-Name or Compounded?
Brand-name and generic, FDA-approved. Qsymia is an approved oral weight-management medication combining phentermine and topiramate extended-release. It is not a GLP-1 and it is not compounded — it has full FDA review of safety, efficacy and manufacturing quality. A generic version became available in May 2025.
Qsymia (phentermine/topiramate ER)
$70/month on 90-day prescriptions through the manufacturer programmeA once-daily oral capsule combining an appetite suppressant with an extended-release anticonvulsant that has weight effects. Clinical reporting describes around 10% weight loss, the highest of any oral weight-loss medication. Titrated gradually to the maintenance dose.
Generic Phentermine/Topiramate ER
Reported from around $50A generic version became available in May 2025. Reported costs have ranged from roughly $50 upward. Ask your pharmacy to price the generic alongside the manufacturer programme — the cheaper route varies by state, pharmacy and prescription length.
Qsymia via Costco
$98 on a 30-day prescription for membersCostco members can access Qsymia at $98 for a 30-day prescription. Note that the associated telehealth service can only offer 30-day prescriptions, which means the $70 rate tied to 90-day prescriptions is not accessible through that route.
Before starting Qsymia, two conversations are essential. First, pregnancy: topiramate is associated with birth defects, so patients who could become pregnant need a clear plan agreed with their clinician. Second, phentermine is a controlled substance with cardiovascular and psychiatric considerations — your full medical and medication history matters here.
Pricing, Membership & Medication Fees
| Cost Item | What You Pay |
|---|---|
| Manufacturer programme | $70 per month, applying to 90-day prescriptions only |
| 90-day prescription availability | Not available in all states — check whether yours qualifies |
| Home delivery pharmacy | Described at $89 |
| Costco members | $98 on a 30-day prescription |
| Telehealth prescriptions | The associated telehealth service can only offer 30-day prescriptions |
| Generic (since May 2025) | Reported from around $50 |
| Discount card pricing | Discount programmes have offered 30-day supplies at reduced cash prices — compare against the manufacturer rate |
| HSA / FSA | Prescription costs are commonly HSA/FSA eligible; confirm with your plan administrator |
The route matters more than the medication here. The $70 rate requires a 90-day prescription that is not available everywhere, and telehealth services offering only 30-day prescriptions push you to $98 or higher. Ask your prescriber whether a 90-day prescription is possible in your state before assuming the lowest advertised figure applies to you.
How Qsymia Works
Have the Pregnancy Conversation First
Topiramate is associated with birth defects. If you could become pregnant, this needs to be discussed and planned for explicitly before you take a first dose — not raised as an afterthought. Your clinician should address contraception and pregnancy testing as part of prescribing.
Disclose Your Full Medical History
Phentermine is a controlled substance with cardiovascular and psychiatric considerations. Be complete about heart conditions, blood pressure, glaucoma, hyperthyroidism, mental health history and every medication you take, including anything for mood or seizures.
Find Out Whether a 90-Day Prescription Is Possible
The $70 manufacturer rate applies to 90-day prescriptions only, and those are not available in every state. Ask your prescriber before assuming. If only 30-day prescriptions are available to you, price the generic and Costco routes against the $89 home delivery option.
Titrate Gradually
Qsymia is titrated upward over several weeks. Side effects including tingling, taste changes, dry mouth and cognitive effects are associated with topiramate. Report them rather than pushing through — dose adjustment is often the answer.
Set Realistic Expectations
Around 10% weight loss is the strongest result among oral medications and a genuine clinical outcome. It is not GLP-1-level weight loss. Knowing that before you start prevents the disappointment that leads patients to abandon effective treatment.
Do Not Stop Abruptly
Topiramate should not be discontinued suddenly. If you want to stop Qsymia, discuss a tapering plan with your prescriber rather than simply ceasing the medication.

Limitations to Know Before You Sign Up
- ⚠Topiramate is associated with birth defects and must not be used in pregnancy. Patients who could become pregnant need explicit contraception and pregnancy-testing planning agreed with their clinician before starting.
- ⚠Phentermine is a controlled substance with cardiovascular and psychiatric considerations, and prescribing restrictions apply. A complete medical and medication history is essential rather than advisable.
- ⚠Weight loss of around 10% is the best available from an oral medication but is substantially below what injectable semaglutide or tirzepatide achieve.
- ⚠The $70 manufacturer rate applies to 90-day prescriptions only, and 90-day prescriptions are not available in all states. Telehealth services associated with the programme can only offer 30-day prescriptions, which pushes you to higher rates.
- ⚠Topiramate is associated with cognitive and neurological side effects including tingling, taste changes and difficulty concentrating. These should be reported rather than tolerated silently.
- ⚠Qsymia should not be stopped abruptly. Discuss a tapering plan with your prescriber before discontinuing.

Frequently Asked Questions
How much does Qsymia cost?
The manufacturer programme advertises $70 per month, with that rate applying to 90-day prescriptions only, and notes 90-day prescriptions are not available in all states. A home delivery pharmacy option is described at $89, and Costco members can pay $98 on a 30-day prescription. A generic became available in May 2025 with reported costs from around $50.
How much weight can you lose on Qsymia?
Clinical reporting describes Qsymia as producing the highest weight loss of any oral weight-loss medication, at around 10%. That is a genuine clinical result but meaningfully below what injectable semaglutide or tirzepatide achieve in trial data.
Is Qsymia a GLP-1?
No. Qsymia combines phentermine, an appetite suppressant, with topiramate extended-release. It works through entirely different mechanisms from GLP-1 receptor agonists, which makes it a genuine alternative for patients who have not tolerated GLP-1s rather than a cheaper version of the same thing.
Can I take Qsymia if I might become pregnant?
This requires an explicit conversation with your clinician before you start. Topiramate is associated with birth defects and must not be used in pregnancy. Prescribing should include contraception planning and pregnancy testing for patients who could become pregnant. Do not treat this as a footnote.
Is there a generic version of Qsymia?
Yes. A generic version of phentermine/topiramate extended-release became available in May 2025, with reported costs from around $50. Ask your pharmacy to price the generic alongside the manufacturer programme, since the cheaper route varies by state, pharmacy and prescription length.
Why is the $70 price hard to get?
The $70 rate applies to 90-day prescriptions only, and 90-day prescriptions are not available in all states. The telehealth service associated with the programme can only offer 30-day prescriptions. Ask your own prescriber whether a 90-day prescription is possible for you before assuming the lowest advertised figure applies.
What are the main side effects?
Topiramate is associated with tingling in the extremities, taste changes, dry mouth and cognitive effects including difficulty concentrating. Phentermine can affect heart rate, blood pressure and sleep. Report side effects to your prescriber rather than pushing through — dose adjustment often helps.
Can I stop taking Qsymia suddenly?
No. Topiramate should not be discontinued abruptly. If you want to stop, discuss a tapering plan with your prescriber rather than simply ceasing the medication.
The Bottom Line
Qsymia earns 3.5 out of 5 stars — the most effective oral weight-loss medication available, at a price that makes effective treatment possible for patients GLP-1s have priced out entirely.
The GLP-1 conversation has become so dominant that it is easy to forget approved alternatives exist. Qsymia produces around 10% weight loss — the highest of any oral weight-loss medication — through mechanisms entirely unrelated to GLP-1 receptors. That last point matters: for a patient who could not tolerate semaglutide or tirzepatide, this is not a weaker version of the same drug but a genuinely different approach. And at $70 a month through the manufacturer programme, with a generic available since May 2025 from around $50, it costs roughly a tenth of brand-name GLP-1 list pricing.
What keeps it from scoring higher is that the safety profile demands more than a menu selection. Topiramate is associated with birth defects and must not be used in pregnancy, which makes explicit contraception and pregnancy planning part of prescribing rather than a caveat. Phentermine is a controlled substance with cardiovascular and psychiatric considerations. And the headline price is harder to access than it looks: the $70 rate requires a 90-day prescription that is not available in every state, and telehealth routes offering only 30-day prescriptions push you to $98 or more.
Our recommendation: Qsymia deserves serious consideration if GLP-1s are unaffordable, unsuitable, or have not been tolerated. Ask your prescriber whether a 90-day prescription is available in your state, and price the generic alongside the manufacturer programme. If GLP-1 therapy is accessible to you and weight loss is the priority, the efficacy gap is real — Coreage RX at a flat $99 puts weekly semaglutide or tirzepatide within a similar monthly budget. Contrave is the other approved oral option worth comparing.
