Oncyclo 25mg Capsule is used to prevent your body from rejecting a new organ after a liver, kidney, or heart transplant. It works by weakening your immune system so that your body does not attack the new organ. It can also be used to treat severe rheumatoid arthritis and a skin condition called psoriasis. The amount of Oncyclo 25mg Capsule you take depends on your weight, medical condition, and what you are being treated for. Your doctor will plan the correct dose for you. Do not change the dose without talking to your doctor. It can be taken with or without food. It is better to take it, in the same way, and at the same time every day to get the maximum benefit. Keep taking it for as long as you have been told to, even if you feel well. Stopping treatment may increase the risk of your transplanted organ being rejected.
