Insurance and other considerations for lamotrigine

Here’s a list of things to consider about the cost of prescription drugs:

• Prior authorization. If you have prescription drug insurance, your insurance company may require prior authorization before it covers the cost of lamotrigine. In this case, your doctor will communicate with your insurance company regarding your prescription for lamotrigine. The insurance company will decide whether to cover the medication. If a drug requires prior authorization and you begin taking it without this, you may have to pay the full price of the drug.
• A 3-month supply. If you’re taking lamotrigine long term, your doctor may suggest a 90-day supply of the medication. This will have to be approved by your insurance company. Getting a 90-day supply could help lower the drug’s cost. It could also save you time having to make trips to your pharmacy.

If you have questions about any of these considerations, ask your doctor or pharmacist. Or contact your insurance company and talk with a representative.

If you don’t have a health insurance plan, let your doctor or pharmacist know. They may suggest online pharmacy options you could use. You can also ask them about ways to obtain health insurance coverage.

Common questions about lamotrigine and cost

Here are some common questions about lamotrigine and their answers. 

Does lamotrigine 25 mg cost less than lamotrigine 200 mg?

It’s possible. The cost of lamotrigine 25 milligrams (mg) versus the cost of lamotrigine 200 mg depends on several factors.

The cost of different strengths of lamotrigine may depend on the form of the drug your doctor prescribes. It can also vary depending on whether you have insurance coverage.

For instance, lamotrigine oral tablets, which are taken by swallowing, come in the following strengths:

• 25 mg,
• 100 mg
• 150 mg
• 200 mg

Lamotrigine also comes in several other forms, and their strengths vary. These forms include:

• extended-release* tablets that are swallowed
• tablets that dissolve in the mouth
• tablets that are chewed and then swallowed
• tablets that can be made into a suspension (type of liquid mixture) that’s swallowed

The drug’s cost may also vary based on your dosage, the pharmacy you use, and whether you have insurance. In some cases, lamotrigine 25 mg may cost less than lamotrigine 200 mg.

If you have questions about the cost of lamotrigine, talk with your doctor, pharmacist, or insurance provider. They can give you more information about this.

* Extended release means the drug is released into your body slowly over a period of time after you take the medication.

Is there a cost difference between lamotrigine extended-release (ER) oral tablet and the drug’s other forms?

Maybe. The cost of lamotrigine ER* oral tablet compared with other forms of the drug may vary. It can depend on whether you have insurance coverage or are paying out of pocket. The cost also depends on your dosage and whether you have any coupons or can use discount programs.

Your doctor or pharmacist can provide more information about the cost of lamotrigine forms.

* ER means the drug is released into your body slowly over a period of time after you take the medication.

Why are costs different for brand-name drugs vs. generic drugs?

Brand-name drugs can be expensive because of the studies needed to test how safe and effective they are.

Makers of a brand-name drug can sell their drug for up to 20 years. When the patent for a brand-name drug expires, other drugmakers can make and sell generic versions. A generic medication is an identical copy of the active drug in a brand-name medication. (An active drug is the ingredient that makes a medication work.)

This competition may help keep costs of generic medications lower. Also, generic medications contain the same active drugs as brand-name medications. So they don’t require the same testing, which can be costly.

If you’d like to know more about the cost differences between brand-name and generic drugs, talk with your doctor.

Generics vs. brand-names

Lamotrigine is a generic medication. The brand-name versions of this drug are shown in the table below:

* Extended release means the drug is released into your body slowly over a period of time after you take the medication.

A generic medication is an identical copy of the active drug in a brand-name medication. (An active drug is the ingredient that makes a medication work.) Generics usually cost less than brand-name drugs. And they’re thought to be as safe and effective as the brand-name versions.

If your doctor has prescribed lamotrigine but you’re interested in taking a brand-name version, let them know. They may prefer one medication over the other. Also, check whether your insurance plan covers only one version of the drug.

To learn how the cost of lamotrigine compares with its brand-name versions, talk with your doctor or pharmacist. You could also contact your insurance company.
