My 17yo daughter was prescribed this as a remedy for her headaches by her doctor because she told the doctor she had migraines. Ive had migraines my whoke life and I think what she is experiencing isn't as bad as what I have to go through when I have a migraine. Is this medicine safe and what are the downside if she starts taking it. Is it normal to use this medicine as a first option to treat migraines?
