Can lasilactone be taken for leg swelling? My father had a bypass surgery in 2013. Recently, he had diarrhea and admitted in hospital. He had fluid drips. Since then, he is having leg swelling problem. Doctor gave lasilactone for  10 days and he finished the course. In between, he also had a fever and another doctor asked him to take lasilactone for leg swelling for 3 days as he still had 10-20% fluid in his lungs. Again, he is getting the leg swelling problem and he has taken lasilactone by himself. Is it advisable??
