Re: What's the half life of Ritalin?

Quotes from two Novartis data sheets:

- prescribing information dated June 21, 2006 for Ritalin (immediate release)
- another dated 14 September, 2006 (Novartis Aust. version)

Peak plasma concentrations achieved at 2 hrs but marked variability between subjects.

Mean half-life is 2.4 hrs in children, 2.1 hrs in adults.

Abstinence is recommended on weekends and school holidays (inasmuch as the clinical situation permits).

Dose should be administered 1 to 2 hrs before maximum effect is required.

Curiously FYI, I recall reading that if you take Ritalin at the same time as modafinil, the latter's absorption is delayed by 1 hr.
