What medication can i use to treat anxiety for my son who is 11 years old?

Avoid meds: The most consistent results for kid/teen anxiety has come from CBT, cognitive behavioral therapy (talk).This is where the therapist explores the reason for the anxiety & teaches the kid skills to master their response. Medications are a backup if the child is truly in trouble, but these should be prescribed by a physician or psychiatrist with experience dealing with the age group.
