I found what looks like the kind of site you need on *********** by searching "drug identification". The 1st site is [url="http://www.stopdrugs.org/identification.html"]www.stopdrugs.org/identification.html[/url] and it shows photos of drugs. When you click on the one that looks like the one your sister is taking it gives you description of it.
Good luck. And I hope it's a harmless one. Whether it is or not, it is NOT a good idea to take someone else's prescription. The amount prescribed is specific to the weight of the person taking it and also his/her diagnosis. Also the prescribing dr. knows what other drugs his patient is taking. If your sister takes other drugs, this new one could have dangerous interactions. Warn her to be careful about this practice.
