To prevent rejection you need to take immunosupressive medication. These medications lower/suppress your immune system so it won't attack the transplanted organ.
cyclosporin, mycophenolate, tacrolimus are examples of immune suppressing medication.
Immunosuppressant
OKT3 prevents is prescribed to prevent organ rejection immediately after surgery and is also used to treat acute rejection episodes
autoimmune medication such as azathiroprine
Doctors can ensure that a transplanted organ works successfully by carefully matching the donor and recipient, prescribing immunosuppressant medications to prevent rejection, closely monitoring the recipient for signs of rejection or infections, and providing long-term follow-up care to maintain the health of the transplanted organ.
Antibodies can cause rejection of the donor organ/ tissue within minutes if the person receiving the organ already had antibodies against the donor. Rejection of donated blood involves antibodies which form the basis of the immune response triggered by the donation. Rejection of a donated kindey or heart involves both antibodies and cell mediated immunity.
Rejection of what? A transplanted organ? Sometimes the body recognises the new organ as a foreign body and attacks it. Medication is given to prevent it usually.
All the drugs used to prevent rejection increase the risk of leukemias and lymphomas.

organ rejection
An azathioprine is an immunosuppressant used in organ transplant and autoimmune diseases to prevent rejection.
The type of drug given to prevent or reduce the body's normal immune response is referred to as an immunosuppressant. This antirejection medication is issued when a new organ is placed inside a patientâ??s body, because otherwise the patient's immune system recognizes the organ as foreign tissue and tries to reject it.
A person who receives an organ or tissue is referred to as a transplant recipient. This individual undergoes surgery to have the donated organ or tissue transplanted into their body to replace a damaged or failing organ. Following the transplant, recipients require ongoing medical care and may need to take immunosuppressant medications to prevent rejection of the transplant.
