The highest therapeutic dose is normally reserved for adults with Narcolepsy and that dose tops out at 80 mg./day total for the immediate-release formula, I believe. However, from what I understand, it is not common to Rx that high of a dose.
For ADHD in adults, the highest dose is 60 mg./day total.
60 mg/ daily is the max dose, unless, as answered above, narcolepsy is only diagnosis allowed to max out at 80mgs daily. Most drs, especially the ones I've been to and/heard about 2nd hand won't start you at higher than 10/day and gradually increase doses over time. I have been on adderall most of my adult life, & EVERYTIME I've had to switch drs for whatever reason, they all make you start at lowest possible clinical dosage and if you,after several months, need more to get the desired therapeutic effect, will only up to 20s... I had to basically beg mine to give me 30/ twice daily, only after he was able to verify from past medical records that I, indeed, had been on that dosage for years.
After just leaving my extremely Pro-Active "concierge" doctor of 5 years- and reading through his medical prescription "dictionary" with him in an effort to find the answer to this question - In Maryland - the highest maximum dose is 40 mg for IR and 30 mg for XR.
We did not see a difference in quantity regardless of reason (i.e. Narcolepsy, ADD, etc.). In fact - the book stated that 20 mg of XR was max dose for adults.
If anyone can advise any different in Maryland - please advise.
So I was diagnosed as a child with ADHD but my family refused treatment and explained it as me being smarter than others. This year (so nearly 20 years later) I saw a nuerologist for a different matter and brought up the possible ADHD. After a few minutes he said adderall would help and started me at 30mg of xr. After 2 months it was increased to 40mg of xr and now a new doctor wants to add an ir in addition to it. I really don't think their is a max. My likely new treatment will be around 70mg a day with almost half being "as needed" I will update after increase if anyone is interested. Having a doctor who understands that the xr does not last 12 hours or even close to that is a huge help in getting proper treatment.
