What are the differences in dosage between ritalin (methylphenidate) and adderall?

Little. Both should be titrated to each patient.
Not exact. Ritalin is the brand name for methylphenidate (mph), and Adderall (dextroamphetamine and racemic amphetamine) is the brand name for amphetamine (amp). Mph is about half as potent as d-amp, so 20 mg of methylphenidate would be roughly 10 mg of d-amp. But, Adderall (dextroamphetamine and racemic amphetamine) is a mix of d- and l-amp, and only d-amp is active; so, the ritalin/adderall ratio is more like 20/15. As dr. Hoffman said: little, especially adding in individual differences.

What are the differences in dosage between ritalin (methylphenidate) and adderall, to achieve the same effects?

Rough estimate below. D-amphetamine (dexedrine) is about twice as potent as methylphenidate (ritalin), so 10 mg of the former is roughly the same as 20 mg of the latter. Adderall (dextroamphetamine and racemic amphetamine) is a mixture of 1/2 d-amphetamine plus 1/2 d- & l-amphetamine (the latter being inactive with respect to adhd. So, conversion from Ritalin to Adderall (dextroamphetamine and racemic amphetamine) is about 20 mg down to 15 mg. But, individual response varies, so that's just a start. Read more...
