For Edema "Lasix (a potassium-depleting drug) made me pee a lot, but didn't do much to decrease swelling. Then I started taking spironolactone (a potassium-sparing drug) and almost overnight I lost almost 10 pounds of excess water. I think the Lasix depleted too much potassium, causing too much retention of sodium (which in turn caused water retention). Note: My diet all along has been low sodium."

For Edema "I started taking this medication when I was in my early 20s for edema. I take 80 mg a day for 20 years now. If I miss a day, I go up about 12 lbs on the scale. This medication has worked wonders for me, but it is hard to take if you need to leave the house. I can pee up to 20 times in 4 hours. Other than the inconvenience, it is a fantastic medication for me."

For Edema "I have a genetic condition called Venous Insufficiency, which doesn't allow the blood & fluid to be returned from my lower legs & feet, so they swell and the skin can start to break down, which opens up the opportunity for infection. Have been taking Furosemide 40mg 1x day for over a year now - it is the only thing that keeps me from being in the hospital all the time with infections that require IV antibiotics. The only side effects I've noticed are the very frequent urination (not really a side effect, it's what the drug is *supposed* to do, as it flushes fluids out of the body), and aching in my legs and feet as the fluid leaves - I can only assume that is caused by my body trying to push the fluid out."

For Edema "I have severe Lymphedema and venous edema with pitting. I made the mistake of taking the medicine at night and was up urinating every 30-40 minutes in large quantities all night. This medicine made me extremely thirsty, so you have to be sure to drink plenty of water when taking this medicine."

For Edema "Dr. has me back on Lasix again for edema and will try another round. The first round was 20 mg. X 2 for 6 mo.s (damn, I was patient) for the swelling in my feet. I was weeing a lot, but it didn't hardly reduce the swelling. I've also noticed a significant increase in the cravings for potassium-laden food, so I believe it HAS drained me of that! Will try to get Doc to increase it to 40 mg all at once, as other reviewers have stated that 20 mg is not enough... and it sure hasn't been for me."

For Edema "Much foot and leg swelling. Just finished 9 days of hospitalization for pneumonia. Took steroids for several days after discharge. As I quit the steroid, swelling started, so I ended up starting Lasix. Urination every 2 hours. I have high blood pressure. Atrial fibrillation. Tremendous sweating. Edema is slowly going down."
