Web Md has opened up a comments section on its site under each of the medicines that it categories. It is allowing consumers of the medicines to comment on how they felt the drug worked, how easy it was to use, as well as if they found any specific side effects. Although a bit cumbersome to use the site is allowing people to really make extended comments on their experience with the drug.
Some would think that the drug companies would have conniptions that their drug is being negatively reviewed, while others would take the opportunity to look into the concerns of the users and view this as an open product review session. If there are side effects that did not show up in the clinical trials, but are emerging for certain populations here is a great way to find out. Patients tell doctors, who tell drug reps, who send the message up the chain. Lots of chances to get that message lost in translation. Here on this site you get (hopefully) honest feedback straight and unfiltered which in my book is the best thing you can do.
