Common questions about phentermine and cost

Here are some common questions about phentermine and their answers. 

When taking phentermine for weight loss, how much does it cost without insurance?

Insurance coverage is a major factor that affects the cost of prescription drugs. In general, prescriptions will cost more without an insurance plan compared to paying through one.

Phentermine is a generic drug. Generics are usually less expensive than brand-name versions. If you’re paying out of pocket, generics will probably save you money over the brand-name drugs.

Also, if you’re paying for phentermine without insurance, you may be able to find online coupons to help with the cost. See the “Coupons for phentermine” section above.

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 medication work.

This competition may help keep the 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.

Cost considerations for phentermine

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

Phentermine is a generic medication. The brand-name versions of this drug are Adipex-P and Lomaira.

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

If your doctor has prescribed phentermine but you’re interested in taking Adipex-P or Lomaira, 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 phentermine compares with its brand-name versions, talk with your doctor or pharmacist. You could also contact your insurance company.
