Hello, my 82 year old mother was rushed to hospital with the diagnosis of needing a valve replacement and bypass-she cannot have this operation. since she has been home for 3 weeks now and a change to her drugs, she sleeps almost all day, numb painful thighs, big loss of appetite. her drugs at the moment are: isosorbide mononitrate, aspirin, atorvastatin, ezetimibe, metoprolol, laxsol, furosemide, spironolactone, perhexiline, diltiazem? I am concerned that her dosages are incorrect because of the change in her, she was becoming forgetful but this seems to have worsened too?
