Methylphenidate & Methyphenidate Sa & Sr

i am on just plain methylphenidate 20 mg tabs. they don't seem to be as effective as they used to be. i was talking to my psychiatrist about switching to something else but he wasn't very agreeable about it. he said these types of drugs are getting more difficult to get. is this true? what is the difference between methylphenidate reg, sa & sr? could this all possibly have something to do with which pharmaseutical companies my doc deals with?

The SR stands for sustained release, so the ones with that designation are a time release formulation, rather than a regular release, like what you are currently taking.

And no, it has nothing to do with any dealings he has with the pharmaceutical companies. If you search our site you will see that many people are having problems getting their prescriptions filled for these types of medications, all over the U.S.

There has been a shortage that the manufacturers appear to have trouble resolving.
