ADHD
"My Daughter has been taking Vyvanse for about 4 years now she is 14 and taking the 50 mg, She usually takes it on school days, So last summer she wasn&#039;t taking it and she started her period but as soon as September came she went back on the 50mg her period never came back. Has anyone experienced this? the doctor said it had nothing to do with the medication but I have a feeling it does."
