i have some pretty dumb pharmacy questions if anyone can answer it. i was afraid of asking the pharmacist i worked with, for fear of being called dumb. 1.) does XL and SR mean the same thing? 2.) pharmacy calls caloptima and workers comp directly for prior auth doctors need to call other insurances( insurances other than caloptima and workers comp) directly to get prior auth. 3.) what's the difference bietween ointment and cream? 4.) what are all the C2 drugs? I know some such as adderall, oxycontin, ms contin, percocet, methadone, concerta, fentanyl patches. Any more? 5.) what does shizm mean? I think that's how it's spell. I always hear the pharmacists say I have to schizm so and so. How do you spell it and what does it exactly mean? Thanks.
