[|AI|]  Hi welcome to Chat Doctor... According to history it is pleural effusion ... So doctors want to treat it with medication if patient respond ... You have not mentioned underlying etiology ... This could be from cardiac failure (as diuretic and digoxin given) or pneumonia like infection (as antibiotic given).... You might have investigated with chest x-ray and EKG for that ... If medicine can't reduce effuse fluid than Chat Doctor. ... Take care Follow doctor advise ... Pulmonologist will be good one for this case
