Epidiolex (cannabidiol) is a prescription drug that’s used to treat seizures. Epidiolex’s cost may depend on factors such as your dosage, whether you have health insurance, and the pharmacy you use.

Epidiolex is used in adults and certain children to treat the following types of seizures:

Epidiolex comes as a liquid solution that you swallow. The active ingredient in Epidiolex is cannabidiol (CBD). An active ingredient is what makes a drug work.

For more details on Epidiolex, see this in-depth article.

The price you pay for Epidiolex can vary. Your cost may depend on your treatment plan, your insurance coverage (if you have it), and the pharmacy you use.

Epidiolex is only available through a specialty pharmacy. This is a pharmacy authorized to carry specialty medications (drugs that are complex, have high prices, are difficult to take, or have special dosage or storage requirements).

To find out how much you’ll pay for Epidiolex, talk with your doctor, pharmacist, or insurance provider.

Note: If you have insurance, you may need to get prior authorization before your insurance provider will cover Epidiolex. This means your insurer and your doctor will discuss Epidiolex in regard to your treatment. Then the insurance company will determine whether the drug is covered. If Epidiolex requires prior authorization and you don’t receive it before you start treatment, you could pay the full cost of the drug.

Be sure to ask your insurance company whether Epidiolex requires prior authorization.

Epidiolex only comes as a brand-name drug. It’s not currently available in a generic version. A generic drug is an exact copy of the active drug in a brand-name medication. Generics tend to cost less than brand-name drugs.

Why is there such a cost difference between brand-name drugs and generics?

Years of research and testing are needed to ensure that brand-name drugs are safe and effective. This testing can make the drugs expensive. The drugmaker of a brand-name drug can sell the drug for up to 20 years. After that, other drugmakers can create generic versions. This competition in the market can lead to lower costs for generics. And because generics have the same active ingredients as brand-name drugs, they don’t need to be studied again. This can also lead to lower generic costs.

If you take Epidiolex long term, you may be able to get a 90-day supply of the medication if approved by your insurance company. This could reduce your number of trips to the pharmacy and help lower the cost of Epidiolex.

If you’re interested in getting a 90-day supply of this drug, talk with your doctor, pharmacist, or insurance provider.
