Drug Interaction Report

Patients that have been treated with allogeneic processed thymus tissue should let their doctor know before receiving hepatitis B adult vaccine. Allogeneic processed thymus tissue is intended to help the body develop a part of the immune system called T cells, which are important to help the body fight infections and can help vaccines work to protect the body against certain diseases. Depending on the length of time since they have been treated with allogeneic processed thymus tissue, their body may not have had enough time to develop this part of the immune system, which may lead to a reduced response to hepatitis B adult vaccine. In some situations, their doctor may want to delay vaccination with hepatitis B adult vaccine until the patient's immune system is improved. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
