My liver transplant was a great success,but after leaving hospital,I began to have periods of breathlessness.This has now got much worse-just walking a few steps or climbing the stairs makes it worse.I am taking 6 mg of prograf daily (3mg in the morning and 3mg in the evening) and 1000mg of microphenolate per day together with 5mg of prednisolone.Do you think my problem is caused by these drugs,or do you think there is more to it?In every other aspect i am fine-my blood results are excellent and my liver function tests are normal.
