If you have questions about the different forms and strengths of phentermine, and what’s right for you, talk with your doctor.
Phentermine is a generic drug. A generic drug is an exact copy of the active drug in a brand-name medication. The generic is considered to be as safe and effective as the original drug. And generics tend to cost less than brand-name drugs.
Phentermine is available in two brand-name forms: Adipex-P and Lomaira.
Both Adipex-P and Lomaira contain phentermine as the active drug. But they contain phentermine in different strengths:
- Adipex-P comes as a tablet or capsule in one strength: 37.5 milligrams (mg).
- Lomaira comes as a tablet in one strength: 8 mg.
This means the 15-mg and 30-mg strengths of phentermine are available only as the generic drug.
In addition, the oral disintegrating tablet form of phentermine is available only as a generic. There’s no brand-name product that comes as an oral disintegrating tablet.
To find out how the cost of Adipex-P or Lomaira compares with the cost of phentermine, talk with your doctor, pharmacist, or insurance provider.
If your doctor has prescribed phentermine and you’re interested in using Adipex-P or Lomaira instead, talk with your doctor. They may have a preference for one version or the other. You’ll also need to check with your insurance provider, as it may cover only one or the other.
Phentermine is not approved to be used for longer than a few weeks. However, the drug may be prescribed off-label for longer treatment of obesity. Off-label drug use means using a drug for a purpose other than what it’s been approved for by the Food and Drug Administration (FDA).
You should not take more phentermine than the dose your doctor prescribes for you. And it’s important that you do not use phentermine for longer than your doctor advises. You and your doctor can discuss the risks and benefits of using phentermine.
Getting a 3-month supply
You may be able to get a 90-day supply of phentermine. If approved by your insurance company, getting a 90-day supply of the drug could reduce your number of trips to the pharmacy and help lower the cost. If you’re interested in this option, check with your doctor or insurance provider.
Using a mail-order pharmacy
Phentermine may be available through a mail-order pharmacy. Using this type of service may help lower the drug’s cost and allow you to receive your medication without leaving home. Some Medicare plans may help cover the cost of mail-order medications. You may also be able to get a 90-day supply of the drug via mail order.
If you don’t have health insurance, talk with your doctor or pharmacist. They may be able to suggest online pharmacy options that could work for you.
