What is the actual name of the diet pills called bird eggs?

Phentermine is nicknamed the bird egg diet pill because of its white and speckled-with-blue color and its oval shape. The drug is used as an appetite suppressant to treat obesity. It works by helping to release certain chemicals in the brain that control appetite. It is classified by the FDA as a Schedule IV controlled substance.
