Hi! I understand you're having trouble checking medications and calculating dosages in the Epocrates app. To help you better, could you let me know if this issue happens when you try specific features, like the drug interaction checker or dosage calculators? Also, are you using the app on your Windows device’s browser, or do you have the Epocrates app installed?

Meanwhile, here are some initial steps that might help:

1. Check Internet Connection: Some features like up-to-date dosage calculators require an internet connection. Ensure your device is connected to the internet.

2. Try Logging Out and Back In: Sometimes, refreshing your session fixes loading issues.

3. Clear Browser Cache: Since you're on Windows using a WebKit-based browser, clearing your browser’s cache and cookies may resolve loading or performance issues.

4. Update or Reinstall the App: If you are using a desktop or mobile app variant of Epocrates, make sure it is updated to the latest version.

5. Use Epocrates Online: If the app’s calculators aren’t working, you can try accessing the online version at epocrates.com to see if the issue persists there.

If these don’t resolve your problem, could you provide more details like any error messages you see or exactly what happens when you try to check meds or calculate dosages? That will help me guide you better.

Are you able to try these steps and let me know how it goes?
