Summary
Dengue vaccine (Dengvaxia) is a live attenuated vaccine, and palbociclib causes neutropenia and myelosuppression. Immune response may be blunted and there is a theoretical risk of vaccine-related infection in immunocompromised patients.
What this interaction means in plain words
Dengue vaccine and Palbociclib can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Why it happens
Myelosuppression from palbociclib may impair the response to the vaccine and permit replication of live attenuated virus.
What to do
Avoid live vaccines during palbociclib therapy and defer vaccination until counts have recovered and treatment is complete as advised by the oncologist. Dengvaxia is also restricted to people with prior dengue infection.
What to ask your pharmacist
- Does the benefit of taking both outweigh the risk in my case?
- Do I need any blood test, ECG or other check while on both?
- What early warning signs should I watch for, and what should I do if they appear?
