As with all medications, the cost of topiramate can vary. Factors that may affect the price you’ll pay include your treatment plan, your insurance coverage, and the pharmacy you use.

To find out what the cost of topiramate will be for you, talk with your doctor, pharmacist, or insurance provider.

Note: If you have insurance, your insurance company may require prior authorization before it covers topiramate. This means the company and your doctor will discuss topiramate in regard to your treatment. The insurance company will then determine whether the medication is covered. If a drug requires prior authorization but you start treatment without the prior approval, you could pay the full cost of the medication. You can ask your insurance company whether topiramate requires prior authorization.

Here are answers to some frequently asked questions about drug cost and topiramate.

If I take topiramate with phentermine, is there a cost difference versus taking topiramate alone?

Yes, there’s likely a cost difference between topiramate/phentermine and topiramate alone. Topiramate/phentermine is the active drug of the brand-name medication Qsymia.* Topiramate alone is available as a generic drug.

Generic drugs typically cost less than brand-name drugs. So taking Qsymia may cost more than taking topiramate. (Currently, Qsymia isn’t available in a generic version.) However, some brand-name forms of topiramate, such as Topamax,† may be similar in price or more expensive than Qsymia.

The cost of either drug will also depend on your insurance plan and the form of topiramate your doctor prescribes. Your pharmacist can help determine the cost of Qsymia versus topiramate. You may also need to talk with your insurance provider and your doctor.

* Qsymia is approved by the Food and Drug Administration (FDA) for long-term weight management in certain people with obesity. For additional details, talk with your doctor or pharmacist.
† Topamax is sometimes prescribed off-label for weight management. Off-label drug use is when an FDA-approved drug is prescribed for a purpose other than what it’s approved for. For more information, talk with your doctor.

Does topiramate 100 mg cost more than topiramate 25 mg?

The 100-milligram (mg) strength of topiramate may cost more than the 25-mg strength. However, they could also cost the same or similar. This is because the cost of topiramate can depend on several factors. These include the form of the drug your doctor prescribes, whether you have insurance, and the pharmacy you use.

Your pharmacist can help determine the cost of different strengths of topiramate.
