This is a sample script to use on the above link that comes up when you click on the firefox icon in the prescribing module. It brings up a page on rxlist.com where you can display drug information, patient handouts etc.
// Search for drug on rxlist.com
drugname = find(/Drugname: (.*)/).groups[1];
go("http://www.rxlist.com/");
enter("search for a drug name", drugname);
click("Drug Information Search");
