I am 76 yrs old and have AF . I am alergic to morphine....cardiac arrest. I am taking the new blood thinner, Pradaxa 110mg., Metoprolol Tart 50mg(1/2 night and am), Lanoxin-PG 62.5 1pm/1am, Frusemide 20mg per day, Micardis Plus 80/12.5, Panadol Osteo 665mg 6 per day plus Caltrate, Glucosmine Have Osteo Arthritis, serious low back (*but can t operate). Had Knee surgery 8 weeks ago. GP now finds my Liver has been failing over the last 12 months. Had a bad fall on my cocktis. Took Pannadol as well. Following knee surgery bled internally and very painfull. (wrong advise given about when I should have stopped taking this drug before op. Suffering pain for the last 12 months I took Panadol when needed as well as Panadol Osteo. More after surgery. Standfs to reason that this could have damaged my liver, but I am worried about Pradaxa or other drugs I am taking. Thinking of going back onto the Warfaran. Please advise. Maxine Johnston
