The profound lymphopenia caused by fludarabine, bendamustine, pentostatin cladrabine...renders patients susceptible to transfusion-associated graft versus host disease, a fatal complication of blood transfusion. For this reason, all patients who have ever received fludarabine should only be given irradiated blood components.
You should carry a card in your wallet stating this in case of an emergency... the hospital gave me one when I was treated with fludarabine...
You can get a Medic Alert also...
Don't expect a paramedic to know...they don't. Unirradiated blood and blood products could be fatal to fludarabine treated CLL patients.
