Prescriptions from doctors and prescription drug containers from chemists could have an address for a webpage for that drug.
Firstly, the webpage would provide more information about that drug.
Secondly, and perhaps more importantly, there would be a forum about the drug on the webpage to enable the users to discuss their drug and their illness with other sufferers. The page would enable contact between users, so that the page would, in effect, form a instant 'support group'.
