I love this app. Love love love it. The Highlights and Basics, Tests, DDx, and Tx tabs under the Quick Reference sections of specific diseases—along with a pharmaceutical dictionary—are indispensable. I truly feel this app makes daily clinical practice easier, smoother, and safer for patients and providers. The ONLY gripe I have about this app is that the News pops up throughout the day, prompting me to click on Headlines before I search for what I need to know, and this is on the PAID version. You are supposed to be able to search for what you need to know from this obligatory News screen. And that would be fine. If it worked. But 9/10 it doesn’t, you can’t, and the app crashes/stalls. I’ve emailed twice about this through the app and received personalized replies, but I could tell they were meaningless…and the issue still hasn’t been resolved. The app is otherwise perfect and if it were a matter of resolving this “issue”/improving the functionality of the app or risk losing the functionality currently available, I would not risk it. That’s how much I value this app.
Totally useless to professionals!

I try to refrain from leaving negative reviews but this is the second time I've been left "stuck" without an answer to a question relying on Epocrates' mobile app. I am a paying customer and I feel that the same quality that goes into your online version should be integrated into your useless mobile app. As a pharmacist I sometimes have questions about dosage forms, medication strengths, formulation types, etc etc. Case in point, today I needed to quickly determine which form of olopatidine is designed for once daily dosing v. twice daily dosing. Simple stuff. I type in Pataday. The mobile app shows "Pataday". I click on it just to be fed to a blank page that says "now OTC"!? Great, where's the other information. So I search generic name where it has so truncated the information that you can't really use it as needed. For example, it lists generic name then both strengths of olopatidine but doesn't differentiate which correlates to the brand, and in this case, drug strength you're looking for. It may sound trivial but this happens often using their mobile site. And don't get me started on finding pK info and any meaningful pregnancy and lactation information on the web app. I really think that for paying users you should create a web version of the online Epocrates platform. I found that very useful in pharmacy school, on rotations, etc. I need that as a mobile friendly version!

Epocrates is my go to App because it is clear and concise and to the point and I can find what I need quickly.I also have another App that is very thorough and shows you studies etc... but personally when I’m taking care of patients I don’t have time to read a study- I need clear, simple and quick answers and that is what Epocrates offers. I’ve used it since NP school and haven’t found anything else that I like better.I’ve worked in the primary care/urgent care setting. The only thing that I would want that Epocrates doesn’t offer (I don’t believe) is A little more info on IV drugs for instance “this should be a slow push over 2 minutes”... obviously we don’t do that in an outpatient setting but when I worked in the hospital those extra tips would have been helpful- I would feel like Epocrates truly had it all of they added that!
Good but...

This app is good, and I’ve only had one complaint until today. The one complaint I’ve always had is the notifications page that automatically pops up every time I open the app. This is frustrating because there are already alerts in the app to tell you that you have new notifications (which I don’t use for anything anyway), and you have to wait for it to pop up to then have the option to close it out and get on with what you opened the app to look up. It just adds annoying extra clicks and takes extra time when you’re trying to get to something fast. The new annoyance with the app is that they are doing away with the DDx feature this month. This feature has been a constant go to for me in school for certain assignments, and our teachers even encouraged us to get the app to be able to use this feature at the beginning of our first year because it would come in so handy for some of the things they want us to do. Such a disappointment that they are suddenly getting rid of this. I turned to this app a lot over other apps because of this feature throughout school and still today, but I guess I will be rethinking my subscription to this app when I have others like it now.

We are pleased to announce that a search bar has been included at the very top of the Doc Alerts page for your convenience. That way, you won't have to navigate away from the page to begin searching for the information you need quickly!The DDx resource was unfortunately removed due to lack of user adoption, but we are very happy to hear that you enjoyed this resource and greatly value your feedback!
