Insurance and other considerations for triamterene

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 triamterene. In this case, your doctor will communicate with your insurance company regarding your prescription for triamterene. 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 triamterene 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.

Generics vs. brand-names

Triamterene is a generic medication. The brand-name version of this drug is Dyrenium.

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 version.

If your doctor has prescribed triamterene but you’re interested in taking Dyrenium, 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 triamterene compares with its brand-name version, talk with your doctor or pharmacist. You could also contact your insurance company. 

Common questions about triamterene and cost

Here are some common questions about triamterene and their answers.  

How does the cost of triamterene compare with the cost of hydrochlorothiazide?

The cost of triamterene compared to hydrochlorothiazide can depend on several factors. These factors can include whether you have insurance coverage or plan to pay out of pocket and how long your treatment lasts.

If you have questions about how much triamterene or hydrochlorothiazide will cost, talk with your doctor, pharmacist, or insurance provider.

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 or pharmacist.
