Postexposure Prophylaxis after Exposure to Hepatitis A Virus

You answered:

C Administer lamivudine for 28 days.

This answer is incorrect. Although lamivudine is an antiviral drug with established efficacy in the treatment  of chronic hepatitis B, there is no evidence that lamivudine has activity against hepatitis A virus (HAV) and thus it would not be recommended in this setting.

A Administer hepatitis A vaccine.
B Administer immune globulin (IG) only.
D Do not administer immune globulin (IG) or hepatitis A vaccine because too much time has passed since the patient was last exposed.
