After any graft/organ transplant, which medications does a patient have to take all his/her life

  1. Immuno modulators

  2. Immuno suppressants

  3. Immuno Competors

  4. Immuno stimulants
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Immunosuppressants are drugs or medicines that lower the body's ability to reject a transplanted organ. Another term for these drugs is anti-rejection drugs. After an organ transplant, the patient needs to take immunosuppressant (anti-rejection) drugs. These drugs help prevent the immune system from attacking ("rejecting") the donor organ. Typically, they are taken for the lifetime of your transplanted organ. Other medications are taken to help the anti-rejection drugs do their job or control their side effects. Patients may also need to take medications for other health conditions.
So the correct option is 'immunosuppressants'.
