I'm taking 30xr Adderall (dextroamphetamine and racemic amphetamine) twice a day and it's not lasting as long. I feel like I need 3 a day to last me through the day. But isn't that a lot.

Yes. Yes, that is a fairly high dose ... But, it's very likely that your system has accommodated to the racemic mixture that comprises Adderall. I'd suggest talking to your doctor about switching to Vyvanse (lisdexamfetamine). It has a longer duration of action than Adderall XR and in the same chemical class. I've had good results with this solution with my patients - Hope that it helps!

Been on Adderall (dextroamphetamine and racemic amphetamine) 25mg XR for over a year now it seems to make me very ill when in me an of don't last but three hours I on 50 mg XR a day?

Time to try some- Thing different. I would recommend a couple of things. The first would be to ask your doctor to check to see if you are a rapid metabolizer of the drug. The doctor can order a cytochrome p450-2d6 iso-enzyme test to find this out. The next option would be to switch to vyvanse, (lisdexamfetamine) and this may be easier to convince your insurance company to pay for if you are indeed a rapid metabolizer through that enzyme system. Otherwise your doctor certainly knows the other medications that could be substituted. Best wishes for a happy and healthy holiday season. Read more...
