The risk of a reaction may be higher in patients with an allergy to dimethylsulfoxide (DMSO), Dextran 40, gentamicin, human serum albumin, bovine (cattle) products, or antibiotics.

You will be given medications to prevent GvHD from occurring. Tell your doctor if you experience any of the following symptoms: maculopapular rash (a rash with flat discolored patches and small raised bumps that may appear anywhere on the body and be itchy), diarrhea, nausea, abdominal cramping, loss of appetite, yellowing of the skin or whites of the eyes, and extreme tiredness.

Omidubicel-onlv injection may cause engraftment syndrome (an inflammatory condition that occurs after stem cell transplant that causes fever, rash, weight gain, pulmonary edema (fluid in the lungs), and confusion). Tell your doctor if you experience any of the following symptoms: fever, rash, difficulty breathing or shortness of breath or shallow breathing, cough, or weight gain.

Omidubicel-onlv injection may cause graft failure (failure to show signs of lasting cell production following cell transplant usually due to immune rejection) which can be fatal. Your doctor will monitor you closely.
