Guideline/Drug Updates and Errata

The RxPrep Course Book is published annually. The year on the cover should be the year in which you are testing. Information in the Course Book is up to date at the time of publishing, but drug information can change rapidly. Refer to the Updates on this page for NAPLEX-relevant information that becomes available before the next RxPrep Course Book is published. Guideline updates that may be relevant to NAPLEX are included. If we find anything that needs a correction or clarification in the RxPrep Course Book it will be included in the Errata table on this page. Guideline/Drug Updates and Errata for the previous version of the RxPrep Course Book (2019) can be found at the bottom of this page.
