Are there any know rash side effects using Marrow Plus? Female, 47 cancer patient, started taking Marrow Plus and Neupgen shot (like Procrit) and a rash appeared. It was under her breast, bilateral down sides, thighs and close to crotch area. No pain, no blisters. She recently came off of Coptecan for 5 days, then started Marrow Plus. Do you think this is from Marrow Plus? She quit taking it and the rash has gotten better. Another consideration is that she is in a hot dry climate that may be source of heat rash.
