Resources like RxTx are really important for practising pharmacists. As we take more responsibility for optimal drug therapy outcomes, there are different kinds of decisions that we are required to make. It’s very helpful to have electronic resources at your fingertips with which you can gain information and the ability to help make decisions when you are taking care of patients.—Stacy Johnson Director of Pharmacy Professional Services, Safeway Pharmacy, Calgary, Alberta


RxTx is a resource that we use regularly at the pharmacy. It’s great because it gives you access to a lot of information in an all-in-one website. It has links to multiple other resources, whether it’s interactions, the CPS or therapeutics. It allows you to identify guidelines for certain conditions and to perform in depth searches on medications. What I like about it is that it’s a site that’s very dependable. I’ve never had any issues with it — to us it’s available 24 hours a day 7 days a week and it’s easily accessible on the desktop computer or mobile device.— Paul Bazin, B.Sc, B.Sc.Pharm, R.Ph Managing Pharmacist, Drugstore Pharmacy 6705 Swift Current, Saskatchewan
