I have been prescribed and taking 2 30mg Adderall XR morning, and 1 30mg afternoon for many years. New insurance only paid for 80mg a day, so I was then given 2 30mg morning and 1 20mg afternoon. A new doctor (PA) insisted the maximum allowable mg is only 60mg a day and would only prescribe 1 30mg and 1 20mg as a daily dose. I am quite certain the max allowable is still 90mg a day and I am just trying to confirm this. I am a 57yr old female, with bi-polar/severe anxiety,depression. Approx. 5'5"/165lbs.
