Doctors Warn Parents About 'Heightmaxxing,' a Viral Trend of Teen Boys Taking a Cancer Drug to Grow Taller

Parents, this one is worth a conversation at the dinner table.

A viral online trend called "heightmaxxing" has teenage boys taking erdafitinib, a cancer drug, in an attempt to grow taller, and doctors are warning of severe health risks.

Erdafitinib is a prescription medicine approved to treat certain cancers. Medical experts told Fox News the risks of misusing it are serious.

Health Check's advice: watch for pills or packages you do not recognize, ask your son what he is seeing online about height, and remind him that no social-media trend is worth risking his health. If you are worried about your child's growth, talk to your pediatrician.
