Insurance and other considerations for diethylpropion

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

If you have questions about this, 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

Diethylpropion is a generic medication. It’s not available in a brand-name version.

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.) Diethylpropion is based on the brand-name versions Tenuate and Tepanil, which are no longer available.

Generics usually cost less than brand-name drugs. And they’re thought to be as safe and effective as the brand-name versions.

Common questions about diethylpropion and cost

Here are some common questions about diethylpropion and their answers.

How does the cost of diethylpropion compare with the cost of phentermine?

Like diethylpropion, phentermine is a generic drug that’s used short term for weight loss. If you have insurance, you can ask your representative for the cost of these medications. If you don’t have insurance, you can ask your pharmacist for more information about the cost. To find out which drug is best for you, ask your doctor or pharmacist.

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.
