I would give the advice to 'research' any drug you are curious about or you have been prescribed. You can even tell your Doctor you intend to 'research' the drug/drugs he thinks is best for you. The Internet is a good place to get common knowledge about a myriad of drugs that are prescribed everyday. There are also books you can look for and, of course, ask your Pharmacists. They really do know allot about drugs and are usually more than happy to consult with you.
There are so many drugs out there on the market - how can a Doctor know them all and 'all' the side effects that they will have on their various patients. It is no fun playing russian roulette with some of these drugs - it is easy for the Doctor to listen to his rep or read something in one of the journals he reads - but, I think 'we' have to be the final judge - after all, we are ingesting them into 'our' bodies, they aren't.
If you have questions about a drug, 'research' it. You will find in quite revealing. Also, your Doctor will more than likely appreciate your input - working 'with'
your Doctor can help his diagnosis be more accurate.
