What is the highest dose of Adderall that is prescribed it to an adult?

Ok... first of all, be respectful of people just because their doctors have probably told them incorrect information! Some of these comments or responses to other people answers were just vicious and it’s not necessary. Here is how it actually works... tolerance's build and once that happens we require a higher dosage. I started taking it when I was 10 and I’m 33 now. 230mg a day and I wish more than anything I never started taking it but it messed with my brains development because it was prescribed to me way too young. There should be a legal limit considering that such high doses aren’t safe simply because you’re tolerance is higher... our hearts don’t develop the same tolerance

Hi, I've been reading over some of your answers and I'm wondering if you all are giving max dose for Adderall or Adderall XR? Is 90 mg of the XR safe? I'm a narcolepsy patient and have been on Adderall for years.

There is no max legal dose. However, as previously stated, government and insurance providers have certainly come up with ways to restrict how much is prescribed. Additionally, the varying locations give credence to any assertion that this is not necessarily ubiquitous and most likely occurs as a result of some ill informed complaint about the prescriber to one of the aforementioned entities (government, insurance organization). Such is the case with my psychiatrist who has all of the suddenly reduced the maximums on benzodiazapines and stimulants. BZDs now stop at 1mg (not including Restoril) and Adderall now ends at 40mg per day.

I know this post is old but I found it interesting. Everyone is different and what works best for them could be a higher dose than someone else. I love in New Hampshire but my Doctor is in Boston. I take 1, 30mg IR & 1, 30mg XR in the morning and then again in the afternoon. Then I take two 20 mg in the evening and I barely feel like it’s working as I have been prescribed since I was much younger. So total I take a day would be 160mg.

To “Spence “ recent reply
What state are you in?
That’s the amount that works for me yet Drs don’t go for it here
It’s frustrating so I try to just deal with barely functioning but it’s horrible

Glad to read someone else understands

I have been on 120 mg of Adderall tablets a day for 6 years for Narcolepsy.

Trials are the FDA used to set max doses. If they only text to 60 mg, that is generally the max dose approved. The max approved dose does not determine the amount the doctor prescribes; each doctor used there discretion & it SHOULD be based in symptoms - also determined by the provider.

I reside in Hawaii, am an adult/adult dose and have been on this medication for many yrs. My dr told me I'm on the highest prescribing dose avail., which is 30mg. x 2 a day (I get 60 pills a mo.). Hope this answer helps... aloha

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.

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.

I am a patient on Adderall for adult ADD and off-label for depression since 2007. I've accidentally dosed up to 150 mg with no ill effects, except the jitters and a little manic behavior.

60 mg.

Personally, I've known patients on up to 270mg per day. That's 9 of the 30 mg tabs. There really is no max dosage. It's an individual basis.

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.
