Migraine
"My 4 year old was diagnosed with migraines (3-4 per month with vomiting and other symptoms).  Given Periactin.  Has had quite an increase in appetite and thus weight gain.  It&#039;s difficult as a parent to balance the weight gain and social issues with that.  Will try going off Periactin in summer per Neurologist. Hopefully the migraines will stay away and she will be able to lose some of the weight."
