How to Identify Phentermine

Phentermine comes in many different forms, dosages, and colors.

While many people are familiar with the white & blue speckled phentermine pills, these popular weight loss pills also come in a variety of other presentations. As a result, it can be difficult to identify phentermine pills.

Phentermine Imprint Codes

Every FDA-approved medication has a unique imprint code

An imprint code is a combination of letters, numbers, words, symbols, or logos that identifies a specific medication. It is assigned by the manufacturer and unique to each product.

The U.S. Food and Drug Administration requires that all medicines (both prescription and OTC) and drug products (both biological and homeopathic) bear a unique imprint code. These markings facilitate the rapid and accurate identification of pills, whether by consumers, medical professionals, or law enforcement ( 1 ).

A prescription medication without an imprint code is likely adulterated, misbranded, or counterfeit.

Fake pharmaceuticals are a dangerous and lucrative business, and phentermine is one of the most commonly counterfeited medications ( 2 ).

So, it’s important that consumers remain vigilant about avoiding fake phentermine.

Fake phentermine is dangerous because it is unregulated and may contain:

  • Dangerous or unknown chemicals
  • Too much or too little of the active ingredient
  • Potentially-harmful substances that should only be used under medical supervision

When purchasing weight loss pills online, be cautious of phentermine imitators with similar-sounding names, similar-looking pills, and/or intentionally misleading advertising. These are all warning signs that the products available for purchase are counterfeit or fake phentermine pills.

It is NOT possible to purchase phentermine online or without a prescription ( 3 ).
