An immunosuppressant is a medicine or drug that lowers a person’s capability to reject the transplanted organ. Immunosuppressant drugs are also called anti-rejection drugs. Commonly, people come across a couple of immunosuppressants like:
Maintenance drugs – This comprises anti rejection medicines that a patient takes for a long time.
Induction drugs – The induction drugs are potent anti rejection medications that are taken during the time of transplant.

Immunosuppressive drugs are some classes of drugs that lessen, suppress, or strengthen the immune system of a person’s body. A few drugs are utilized for making the human body less likely to reject some transplanted organs, like kidneys, heart, or liver. There are some other immunosuppressant drugs too that are utilized for treating a few autoimmune disorders, like psoriasis, rheumatoid arthritis, and lupus.
If a physician recommends a patient immunosuppressive medication, then he should be aware of the functions of these drugs, the method in which they work, besides how these medications might make him feel.
Types of Immunosuppressive Agent
Corticosteroids is the most common immunosuppressant that most doctors prescribe. Based on the condition and symptoms the doctor prescribes one immunosuppressive or a combination of it.
Liquid, pill or Injection shot, immunosuppressives can be of any type. The types include -
Calcineurin inhibitors like tacrolimus and cyclosporine.
Biologics such as infliximab , adalimumab etc.
Corticosteroids (prednisone).
Janus kinase like tofacitinib.
Inosine monophosphate dehydrogenase like mycophenolate mofetil.
Rapamycin as sirolimus.
Monoclonal antibodies like basiliximab.
Immunosuppressive therapy is commonly utilized for aiding organ transplants. The body of a patient does feel a foreign object before his immune system does attack it. Immunosuppressive drugs are helpful in lessening the danger of a patient who rejects a new organ. This therapy is considered a drug routine that patients utilize for lowering the immune responses of their bodies. These drugs turn helpful to the doctors for stopping patients’ immune systems from overreacting as well as damaging transplanted tissues and organs. Commonly, everyone is needed to take some immunosuppressant drugs while getting an organ transplant. Only in some cases a patient doesn’t take these drugs.
Immunosuppressive therapy turns useful for treating some immunosuppressive diseases besides organ transplants, and they are:
Multiple sclerosis
Inflammatory bowel disease, like Ulcerative Colitis and Crohn’s Disease
Myelodysplastic Syndromes or MDS
Lupus
Aplastic anaemia
Rheumatoid arthritis
The side effects of immunosuppressants do vary for different immunosuppressant drugs that are obtainable. For finding out the side effects, you need to consult your physician or the pharmacist. Nonetheless, it is important to note that every immunosuppressant drug carries a severe danger of infection. If an immunosuppressant drug does weaken your immune system, then your body turns less resistant to infections. It also means they turn you more prone to getting infections. This also signifies that the infections will turn out to be tougher for treating.
When you get the symptoms of infection mentioned below, you need to get in touch with a physician.
Trouble in urinating
Chills or fever
Pain when you urinate
Pain in your lower back’s side
Weakness or abnormal tiredness
Frequent urination
You need to be mindful that immunosuppressants can leave a potent effect on your body, and so, a healthcare provider does suggest having regular blood tests done. This will ensure that the levels of medication have not reached a higher level. Some other side effects are:
Diabetes
Acne
Headaches
The slow growth of hair
Fatigue
Tremors
High blood pressure
Stomach upset along with vomiting and nausea
Weight gain
Thinning bones or osteoporosis
Mouth sores
1. What is an immunosuppressant?
An immunosuppressant is a drug that reduces or inhibits the activity of the immune system. It works by decreasing the activation and proliferation of immune cells, especially T lymphocytes and B lymphocytes.
2. How do immunosuppressant drugs work?
Immunosuppressant drugs work by blocking specific steps in the immune response, particularly the activation and division of immune cells. Different classes act through different mechanisms:
3. Why are immunosuppressants used after organ transplantation?
Immunosuppressants are used after organ transplantation to prevent graft rejection by suppressing the recipient’s immune response against the transplanted organ. The immune system recognizes the new organ as foreign due to different antigens (especially HLA molecules).
4. What are common examples of immunosuppressant drugs?
Common examples of immunosuppressant drugs include cyclosporine, tacrolimus, azathioprine, methotrexate, and corticosteroids. These drugs belong to different classes:
5. What is the difference between immunosuppressants and anti-inflammatory drugs?
The main difference is that immunosuppressants broadly reduce immune system activity, while anti-inflammatory drugs mainly reduce inflammation without fully suppressing immune function.
6. What are the side effects of immunosuppressants?
The major side effect of immunosuppressants is an increased risk of infections due to reduced immune defense. Other common side effects include:
7. How do immunosuppressants affect T cells?
Immunosuppressants primarily inhibit the activation, proliferation, or function of T cells, which are central to adaptive immunity. They act by:
8. Are immunosuppressants used to treat autoimmune diseases?
Yes, immunosuppressants are commonly used to treat autoimmune diseases by reducing the immune attack on the body’s own tissues. In autoimmune disorders, the immune system mistakenly targets self-antigens.
9. What is the difference between immunosuppression and immunodeficiency?
The difference is that immunosuppression is a reduced immune response caused intentionally or by external factors, while immunodeficiency is an inherent or acquired defect in the immune system.
10. Can immunosuppressants increase the risk of cancer?
Yes, long-term use of immunosuppressants can increase the risk of certain cancers due to reduced immune surveillance. The immune system normally detects and destroys abnormal cells.
