Lasix (furosemide) 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."

Lasix (furosemide) for High Blood Pressure "This medication was ineffective for me - years ago, I had a mini-stroke, also known as a TIA. At first, this helped a little bit, but when you have 158/90 BP, you need more than a 5% reduction in it. This medication made me severely dehydrated and caused significant electrolyte loss. I quit it and tried Chlorthalidone, but that again failed - if you only have mild elevated BP, this could be OK; if you have significant hypertension, though, you are much better suited to a real medication, such as a beta blocker."

For Edema "I have been diagnosed with CHF and have had many bouts with pitted edema. During the first few times of extreme swelling, I had already been prescribed furosemide, which is supposed to help with fluid retention. Unfortunately, that was not my experience while dealing with a severe case of pitted edema. I found the furosemide did absolutely nothing, and I mean NOTHING!! I was taking 80 mg twice a day and at times could not urinate at all. After retaining 100 extra lbs. of fluid in a 6-week span, I was forced to go to the ER. I spent 22 days in the IMU unit with 4 IVs pumping 4 different diuretics. Furosemide may work for some, but it only left me feeling dehydrated, severely swollen, and with a horrible case of 'cotton mouth.'"

For Edema "I took my first dose of furosemide yesterday morning, 1 x 20 mg tablet at 6:00 a.m. (when I take other medicines). I fell asleep and woke at 11:15 a.m. and felt tipsy, restless, and had twitches and tingling in my hands and fingers. I also had a very dry mouth and was very thirsty and did more housework than I've done in the last 3 months put together. I suffer from chronic back pain and chronic sciatica, and even though I was in a great deal of pain, I couldn't stop cleaning. Today I still don't feel quite right, and every muscle screams in protest as I move."
