I am probably going to ask my doctor to put me back on Focalin. I was prescribed 10MG IR and 10MG XR. The IR worked very well but the XR did not work. Am I supposed to be on a higher dose of XR? Also, is it abnormal to take 2 XR's a day and none of the IR's.

It's my understanding that 10 mg XR is equivalent of two 5 mg IR, one that releases right away, one later basically. I don't know about the taking 2 XRs per day and none of the IRs. I take one 30 mg XR in the morning and one 10 mg IR in the afternoon, so basically two 15s and a 10. Of course the XR is the brand, and IR is generic, and generics can make a huge difference too. I would tell your doc that the IR worked well and maybe he will put you on 20 mg XR and 10 mg IR if you need the boost later in the day. Good luck!
