Chemically, I don't know. That's what I was hoping to find. I know that if I don't take it, I know it. That day. As it has been explained to me, it lasts for the prescribed time, then is gone. That's why it's a daily dose. I take 60 mg a day. I would prefer 50 but they don't make a 50 mg dose. Nor do they make a 60 mg but I take (2) 30 mg at a time. The long acting (LA) version since my days are typically longer than 12 hours, which is the prescribed effective time. I have found that sleep deprivation, a common occurence for me, will shorten the effective time.

How long does methylin or Ritalin stay in urine?

Ritalin can be detected for 1-5 days in urine, but it is not part of the SAMHSA/ NIDA-5 standard drug test. Also Ritalin can cause false positives for methamphetamine/ amphetamines. If you have a prescription for it, notify them before the test. Or if test came up positive and you did not use meth, you should insist on additional GC/MS testing.
