Found that in the headache section of the "Dealing w/ Doctors" info. Just because it's approved doesn't mean it's gauranteed. Hope his Dr. helped. Wonder if maybe he was on too much depakote........... Being such a tiny guy & all.
"One of the best ways to deal with headaches is to prevent them. In a new use for a drug that’s been around awhile, the anti-seizure drug Depakote has been approved by the FDA to treat migraine headaches."
