You prescribe sterculia. An hour later, you are paged to see Andrew who continues to be unwell.

You reflect on the events of the evening and realize that sterculia is a bulk laxative. It is indicated to treat constipation and you remember that it takes a few days to act. You realize that you have mixed up sterculia with another laxative that may be used to treat hepatic encephalopathy, and that this error contributed to Andrew's worsening state.  

Please go back and try again.
