Aretha Tablet belongs to a group of medicines called immunosuppressants. It is used with other medicines to prevent your body from rejecting an organ (such as a kidney, heart, or liver) after a transplant. It is also used in the treatment of rheumatoid arthritis. Aretha Tablet works by weakening the body’s immune system, so it does not attack the new organ. The amount of medicine to be taken and how often you need to take it will depend on the type of transplant you have. Follow your doctor’s instructions on this. You should take it along with food. Take the medicine regularly to get the most benefit and keep taking it even if you feel well. If you stop taking it, you may increase the chances of rejecting your transplanted organ. It has many potential side effects. The most common are loss of appetite, nausea, and increased risk of bleeding. Because it suppresses your immune system, you may catch infections easily. There’s also an increased risk of developing some cancers for this reason. You should ask your doctor about side effects that may need urgent medical attention. Aretha Tablet can cause birth defects and miscarriages so do not take it if you are pregnant, planning to become pregnant, or breastfeeding. You should talk to your doctor before taking this medicine if you have any signs of infection or if you have any unexpected bruising or bleeding. Your doctor also needs to know what other medicines you are taking as there are many which interact with this medicine and affect the way it works. You will have regular tests to check for any changes in the number of your blood cells.
