SDN Members don't see this ad. (About Ads) I'm an ER intern and I constantly have to write prescriptions and I'm always wondering if I'm doing it right. I especially hate writing prescriptions for kids and calculating the liquid amounts and how much to dispense. Is there a website that teaches doctors how to write prescriptions? I primarily use epocrates but i always find it confusing when calculating liquids and especially if it's like a "div every 6-8h" which is different than just plain "q6-8h" some have told me to write, "use as directed" or whatever but that seems kinda wrong and extra work for the pharmacy.
