My daughter is going to be 8 next month she is autistic and she will not sleep at all at night time so first the Dr puts her on melatonin that didn't do anything for her so they put her on clonidine and she was on that for a while but then that stopped working she didn't sleep at all that night and stayed up rest of day so I called dr and now she is on trazodone 50mg it worksbut reading about it makes me worry for age.
