I wonder why he is putting her on such an old drug with such terrible side effects. The doctor at first put my young son on 10 mg 4 times a day and he was like a walking zombie...walked out in front of cars and just strange and dangerous things like that. It was summer time and they were outside playing in the little pool ...he held his little sisters head under water without realizing what he was doing. I said nuts to this so as it turned out he just needed on 10mg at bedtime. Amitriptyline has many side effects esp. for the young so why hasn't he prescribed the newer drugs for Migraines...like (Imitrex), naratriptan (Amerge), rizatriptan (Maxalt) and zolmitriptan (Zomig)? One of my doctors young son gets migraines and she treats him with Imitrex.
