Which product is listed as a hospital management option for parvo but not outpatient?

• A. Hyperimmune serum from a vaccinated dog
• B. Tamiflu
• C. Interferon omega
• D. Maropitant

Answer: (A)

Parvovirus management hinges on providing passive immunity to help neutralize the virus while aggressive supportive care is given in hospital. Hyperimmune serum from a vaccinated donor contains high levels of antibodies against parvovirus, directly helping to control the infection and supporting the puppy’s recovery when monitoring and IV administration are available. Because it requires careful handling, blood-product screening, and close observation for transfusion reactions, this therapy is typically limited to a hospital setting rather than outpatient care.

Other options do not fit as hospital-only: Tamiflu targets influenza and isn’t effective against parvovirus; interferon omega is an immunomodulator with variable use for parvo but not a standard hospital-only option; maropitant is an antiemetic used both in hospital and at home for vomiting.
