quick question | ADHD Information

Share
what is the approximate dosage equivalent between Ritalin (methylphenidate) and Dextrostat (dexedrine sulphate)?

e.g. does 20mg methylphenidate equal ~12 mg of dexedrine?

I seem to recall the conversion being 0.6. Can anyone confirm this?

Thanks so much.

Paul

why?

 

Good question Micheal.... i'd like to know why too.  It seems a bit strange.  is this for a cocktail drug or what?

Hi Paul i'm sure i read somewhere that 10mg of Ritalin = 5mg of Dexamphetamine (Dexadrine) but don't quote me on that.

I do know for sure that both meds are similar, but work in a different way to combat the ADHD. In any case if you or someone you know is considering changing, mixing or adjusting their meds it is always best to do so under medical supervision. These meds are quite hard on the body and can be very unforgiving at times

Like the guys above i also am curious as to why you ask as playing around with different meds or creating a drug cocktail can be quite dangerous.

I will try and find where i saw the conversion and post a link back here. Please read other posts on the forum as there is a wealth of information available, as well as other peoples experiences both good and bad that will also help you out.

For those who are interested in what meds are available, and all their info including dosage, effects this link might be helpful:

This may have been put up on the board elsewhere as well, but this might help compare dosages between the 2 meds.

Hope this helps.

Thanks everyone for your help.

Q. Why?
A. I was changing from Dexedrine to Ritalin.

I was taking 10 mg dexadrine sulphate three times a day so I needed to figure out approximately how much Ritalin I would need. It turns out that 20 mg Ritalin three times a day works.

So far (for me) I seem to have  less appetite suppression and insomnia.

Don't worry I am working very closely on my medication management with an excellent psychiatrist.
thanks for not taking what i said as offensive.  We get alot of people here that are looking for a cocktail.  Glad that you are working with you dr.  It is good to know what you are taking.Please help I'm trying to figure this out and I know someone must know off the top of their head.

10mg of Dex. is equal to 20mgs of Ritalin.....etc. Dex is twice as potent as Ritalin..........

Also, Adderall is three times as potent as Ritalin, and twice as potent as Dex.  Example:  10mg of Adderall is equal to 30mgs of Ritalin and 20mgs of Dexedrine.

Hope that helps

Also, in sustained-release pills (doesn't matter what kind)  cut that dose in half and that is what you are actually getting.............example

20mgs of RitalinSR is equal to 10 over a longer period.
