Summary
Ifosfamide causes myelosuppression and lymphopenia, which can blunt the antibody response to an inactivated influenza vaccine. Protection may be incomplete, but the vaccine cannot cause infection, so the combination is not contraindicated.
What this interaction means in plain words
Ifosfamide and Influenza virus vaccine quadrivalent cell-cultured can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Cytotoxic suppression of lymphocyte function reduces the immune response to the vaccine antigen.
What to do
Vaccinate annually anyway, ideally before chemotherapy starts or between cycles when counts have recovered. Do not rely on the response alone and apply other infection-prevention measures.
What to ask your pharmacist
- Should I take them at different times of day?
- Does the dose of either medicine need to change?
