Seek emergency care for severe difficulty breathing, chest pain, fainting, confusion, uncontrolled bleeding, severe dehydration, or widespread blistering or peeling skin.
If possible, tell emergency staff that you have had an allogeneic stem cell transplant and may be taking immune-suppressing medicines.
Contact your transplant team promptly about any new rash, diarrhea, vomiting, jaundice, mouth soreness, eye discomfort, cough, breathlessness, genital pain, reduced joint movement, or unexpected weight loss.
Prompt contact is also important if known GVHD worsens or if prescribed medicines cannot be taken.
Seek urgent medical advice for frequent watery diarrhea, inability to keep fluids down, rapidly spreading rash, new yellowing of the skin or eyes, worsening breathlessness, or signs of infection such as fever or shaking chills.
Follow the specific fever plan given by your transplant centre.
Routine follow-up remains important even when symptoms are stable.
Some lung, eye, liver, or mouth changes can develop gradually and may be found during monitoring.
