We have no clear estimate of how many children with autism receive medications now or have received them in the past. We do know, however, which classes of medication are prescribed most commonly for different symptom clusters. Within each group we have briefly described the intended benefits and potential side effects of each medication. These medications are prescribed for children as young as three, but may be helpful at any age up to adulthood. In contrast to most other medications, stimulants act quickly and response can be seen within days or sometimes even hours.
Blood pressure lowering action is a minor side effect, and incidental to their intended action.
Tenex Guanfacine Same as clonidine Sedation, may interact with anticonvulsant Depakote Antidepressants are third-line treatments for attention problems and hyperactivity. Benefits are incidental to antidepressant action, and a response does not imply that the child was depressed. It often takes weeks to see benefits. This newer class of medications has a lower level of side effects. What is particularly important is their lower rate of tardive dyskinesia, a movement disorder that resulted from prolonged neuroleptic usage, for which no satisfactory treatment exists.
