<s>[INST] I had a shoulder cuff repair 4 weeks ago. I am 73 with CHF & COPD I weigh 268 normally. I have been holding water. My legs are swollen, causing me pain, unstable , & weak. my weight this morning ie 280lbs I take 2, 20mg lasix (furosemide) twice a day normally = 40 mg. yesterday I took 60 mg I do not notice any difference this morning. question, how often can I take lasix to take off the fluid. thank you. Jerry Hauser 03835 NH [/INST] Hello, Taking Lasix daily is the normal dose. Do not increase the dose without consulting your physician as it can cause an electrolyte imbalance. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Praveen Tayal, Orthopaedic Surgeon </s>
