You are reviewing a 57 year old in cardiology clinic who was recently started on a new medication for an irregular heartbeat. He tells you that he is becoming increasingly short of breath and is no longer able to play golf or walk his dog. He has read that the medication can cause lasting lung damage and is very upset about this. Additionally, his GP has told him that his thyroid tests are abnormal. He would like to stop this medication immediately and wants to know how long it will take before it is “out of his system”. What is the half-life of this medication?
