Librium 50-100 mg PO TID or QID. Have strict instructions on when to return to ED.

73
Q

If a Pt states that they have no interest in quitting drinking, and plan to go home and drink after being discharged can you D/C them?

A

Depends, if they are unstable you shouldn’t D/C them. If they are stable and plan to go home and drink it’s okay to D/C as continuing drinking is safer than going through alcohol withdrawal. A weird concept I know, but you can’t stop someone who isn’t ready to quit.

74
