If you're concerned because you don't know about these drugs, check out the following sites for more information on them:
www.medlineplus.com -- this site has drug info from both the USPDI and Medscape. It's basic patient info, which does overlist all the side effects, as usual.
www.rxlist.com -- this site has the most detailed information, which may be overwhelming to you. If you really want to know every detail available on the drugs, though, give it a try.
www.pdr.net -- this site has a patient's info section, where you can look up what the PDR has to say about drugs.
I hope that more information helps ease your mind.
