Diabetes Home > Generic Metanx

Because Metanx is considered a "medical food," rather than a prescription medication, it does not have to be approved by the U.S. Food and Drug Administration. Although there are products available that have active ingredients similar to Metanx, there are no supplements that are considered a brand-name or generic Metanx product. However, it may be less expensive to take the individual components of Metanx separately.

Can I Buy Generic Metanx?

Metanx® is considered a "medical food," and is used to help manage symptoms of peripheral neuropathy in people with diabetes. It may also be used in people who have high levels of homocysteine in the blood (hyperhomocysteinemia). Metanx is only available with a prescription and should only be used under medical supervision.
Metanx is made by Pamlab, L.L.C. Technically, there are no generic versions of this product.

When Will a Generic Version Be Available?

All generic medications must undergo certain tests to compare them to brand-name medications. The U.S. Food and Drug Administration (FDA) then looks at these tests to decide if the generics are equivalent to the brand-name medications and assigns each generic a rating.
Metanx is considered a medical food, not a prescription medication. Medical foods are used to provide nutritional supplementation for medical conditions that have specific nutritional needs. They do not need to be approved by the FDA. Therefore, no testing is done to determine if products are equivalent. This means that, technically, there are no brand-name or generic versions of medical foods.

Are Similar Products Available?

Metanx contains active forms of three vitamins: folic acid, vitamin B6, and vitamin B12. There are currently no products available that contain the exact same ingredients as Metanx. However, there are a few products that have similar active vitamins, such as Folast™, Foltx®, and Folbic™ tablets.
Some people may wonder about taking the individual vitamins found in Metanx separately. This would require taking multiple pills a day, instead of just one or two Metanx tablets, but could be less expensive, especially if Metanx is not covered by your insurance. If this is an option you would like to consider, talk to your healthcare provider first. He or she can help you determine if this is the best approach for your situation, and tell you how much of the individual vitamins to take.
