You can use Lexidrug (formerly Lexicomp) to see OHSU Formulary information.
Lexidrug does not allow you to browse OHSU Formulary entries. However, if you search on a drug name and it is in the OHSU Hospital Formulary, you will see an entry at the top of the results titled "Oregon Health and Science University Hospital" with a link to the drug name.
The screenshot below shows a search result for "propranolol" with the formulary link.
If a drug is not included in the OHSU Hospital Formulary, your search will still have an "Oregon Health and Science University Hospital" entry at the top, but with "No occurrences" noted beneath it. The screenshot below shows a search result for "byetta" with no formulary entry for this drug.
