A 37-year-old member asked:

Could you tell me what happens if a person forgets to take his medication after a liver and kidney transplant?

1: The medications given after a liver/kidney transplant suppress the body's ability to recognize that the transplanted organs are foreign, thus they prevent the body from rejecting the donated tissue. If you forget to take your meds, the blood levels of the medications in your blood starts to decrease. If you do not take the meds for a long enough time, your body will reject the transplants.

Rejection can begin.: Even skipping a single dose of anti-rejection medicine can begin the process of rejection. If this occurs, the organs will not last as long and both quality of life and life expectancy can be decreased. Once you realize that you made a mistake, you should take your medicine and call your transplant center. They can help you get back on track and see if you need additional treatment.

Rejection risk: Unless the txps came from an identical twin or clone, they are genetically different from you. Your immune system is tricked into ignoring their presence by meds prescribed to prevent rejection. Not taking a med, lets the drug level drop, and the portion of the immune response that should be blocked, to begin functioning. Take the missed dose as soon as possible. If it is mult. Doses, call your md.

Forgets?: If you miss the anti-rejeciton drugs for one day, likely nothing. But if it becomes a pattern, you are taking a risk that you can develop a rejection episode and lose the graft. You should discuss these tendencies with your transplant team if there is a pattern.
