Is anyone else having trouble getting their Quillichew prescriptions filled? My son has been on Quillivant for few years and now I can’t find it anywhere. His doctor wrote a prescription for QuilliChew but I cannot find a pharmacy that has it. I’m not sure what medication is similar to this brand. He’s tried Concerta and had really bad headaches not to mention the loss of appetite. He also had a loss of appetite with Quillivant but it was manageable. I’ve called Tris Pharma who’s now taken over for Pfizer but I can’t seem to get an answer on when QuilliChew or Quillivant will be available.
