"Our 13-year-old son shows no sign of puberty. Could his medications be causing a delay?"
Larry Silver, M.D.
Neither Wellbutrin nor stimulant medications are known to delay the onset of puberty, and there's nothing unusual about a pre-pubescent 13-year-old. Discuss your concerns with your son's physician. One option is to request that certain bone-growth sites be X-rayed or hormonal levels be checked. If they are normal, just relax and wait. If you are truly concerned, consult a pediatric endocrinologist.
