Adolescents take erdafitinib, a bladder cancer drug approved for advanced cases.

Doctors warn

Dr. Stephanie Widmer says drugs were developed for serious conditions, not height enhancement.

“These drugs were developed to treat serious medical conditions, not to enhance physical appearance”

Safety concerns

Dr. Jessica Gray warns of skeletal damage and bone fractures from rapid growth.

“Forced, rapid growth can trigger dangerous structural problems, including premature growth plate damage and bone fractures”

Side effects

Side effects

Side effects include vision damage, metabolic issues and skeletal pain.

“These medications can cause serious side effects, including potentially permanent vision damage”

No growth after puberty

Growth plates close by end of puberty, so older teens can't gain height with this drug.

“Once growth plates close near the end of puberty, medications cannot reopen them”

Medical advice

Parents should consult pediatricians before teens use online medications.

“If a child has concerns about their growth, that conversation belongs in a pediatrician’s office, not on an internet forum”
