My youngest son was diagnosed with having adhd. he was taking folcolin, he doesnt like it. what other pills can he take?

Many options : There are many pills available for ADHD. The majority are stimulant based. There are a couple of non-stimulant type medicines but they are not as effective in my opinion. There is even a patch. I would tell his physician and see if he can be put on a different medicine. Vyvanse, Concerta, and amphetamine salts would be some of the alternatives.
