Question: Mom is 94. Has cong heart failure as a diagnosis. 5 ft...106 lbs... one kidney. One month ago, she developed wheezing and short of breath , more edema in lower legs, gained 3 lbs. Began 20 mg ... then a few days later 40 mg of lasix....Echocardiogram showed fluid in pleural space. Got thoracentesis 10 days ago. Removed 350 cc of fluid from one space... nothing in other space. Began 2 liters of oxygen... now taking only when sleeping...ox rate is 92 now without the oxy on.... 98 with it on...Since then—- no sob or wheeze... ankles fluid way down... weight is 102 ( probably because of lasix and low salt diet) Very sleepy yesterday.. sleeps all the time.....the doctor said stop the lasix and watch the salt intake and do more drinking. Drink fluid to avoid dehydration.
Is it ok to stop lasix abruptly , all at once, or should I gradually stop lasix ??
What symptoms do I look for to start back the lasix???

Before 1 month ago, she wasn’t taking any lasix at all. Then after the wheezing, SOB , oxy level without oxygen on was 85 !!!, and lower leg putting edema, she began 20 mg of lasix daily, but that didn’t help for 5 days , so they increased to 40 mg, and did the thoracentesis, where they took off 350cc from pleural space on1 lung. The improvement wasn’t immediate , but within 3 days, the SOB and wheezing were gone, she felt better , and even her oxygen level without oxygen on, was up to 92. With oxygen on it is 98. Her weight had dropped from 107 to now 102..... probably due to lasix and not eating as much?? So, since I noticed moms legs were much improved, she stopped the SOB, etc and breathing easier, and oxy level was much better, I wanted to see if we should stop the 20 mg of lasix.... or continue to take 20 mg daily?? and the last 20 mg of lasix she took was 48 hours ago. One doctor said that we could take lasix again if symptoms returned, but I need to know what you think.......
She has htn and takes the previously mentioned meds for htn. She has A Fib but only occasional ( one episode every two weeks)’flare ups of erratic heart beats , which last only about 2 hours , and increased metoprolol gets heart rate into synus rythem.She has had afib for over 8 years.
She has had 3 or 4 “ tia” episodes, but not for about 2 months. I don’t know the ejection fraction. Thanks
I was worried that abruptly stopping lasix completely would be harmful .

I uploaded the only reports I have . I’m not sure it’s what is needed. I gave mom 20 mg of lasix today and we give it every other day now
