Alternative to Pamelor

A neurologist has perscribed this drug to my 11 year old daughter, after she was on Trisprentec for a week and developed a migrane (migraine) headache she has now had for almost 4 weeks.    After reading the side effects I am wondering if there is anything else that would help her.  Her pediatrician perscribed (in order given) Ibprohen, Tylenol, Imitrex, Maltrax, Lortab, Phenegran, with Lortab, and Baby Asprin. Nothing worked.  Then she went for a week with no medication since nothing worked. Now, upon our first visit tothe neurologist, he wants her to take Pamelor, which after reading I have major concerns, considering she is a very intellligent child. We eat healthy orgainic food, 95% of the time. I don't want to impair her developing brain in anyway. First, what do you think about someone her age taking this? (He wants her to be on this 6 weeks) and taking 10 mg the first week and 20 mg the second week and there on I guess 20 mg.  I have spoken with a chemist professor @ a  local university, and from his info this seems quite the "sledgehammer" approach. Also, is the generic version any better? And last, what is an alternative drug she could use?

Although not an FDA-approved indication, Pamelor has been prescribed for migraine prophylaxis. Children 6 years and older can take Pamelor, and the maximum daily dose is 150 mg.  10 mg is the usual starting dose. As she has not responded to other medications, this seems to be a reasonable alternative to try.
