Furosemide for Edema "I was prescribed the generic form of Lasix a few days ago for severe peripheral edema. The doctor had me taking 20 mg twice a day for three days and now I'm taking 20 mg. So far, I have noticed only a subtle difference/improvement in the major swelling of my feet, ankles, legs, and abdomen. I am experiencing an increase in frequency of urination, as others have described, but it doesn't seem like I'm voiding enough, which may be why I am still so swollen. It has been only four days on Lasix and I am in terrible pain. Hopefully, the swelling will subside or at least decrease, otherwise, I will be contacting the MD for advice. I have also experienced headaches daily since I began the medication. I have been extremely dizzy as well."

Furosemide for Edema "I really had edema all over my body (i.e. face, hands, feet), but especially on my legs! I went to my doctor and she prescribed this medication to me, it's working like magic! I take it in the morning as soon as I wake up. I noticed it's more effective when taken on an empty stomach, then after breakfast, and so on. I had to deal with some headaches (minor), but it was definitely worth it!"

Furosemide for Edema "I have had pitting edema, severe water retention all over my body mainly my face, hands, ankles, feet, and lower legs. I also have felt the side effects of side aches and leg discomfort. But I have come to find out I also suffered from RLS (restless leg syndrome). I do suffer from very minor headaches. But when one day you are swollen as a balloon and about 2 to 3 days later you are unswollen. I first started out on 10 mg as needed, then had to go up to 20mg when required, then daily. Then eventually kept raising it by 20 after that to 40mg daily. Then I ended up having to take 2 x 40 mg daily, 2 x a day. I also have insulin resistance/metabolic syndrome so that may have something to do with it. I'm now at 80mg daily."

Furosemide for Edema "I have been using Lasix in combination with Hydrochlorothiazide for 6 months for pitting edema/hypertension, and its effects seem to have worn off. I started on 20mg once a day for 2 months then up to 40mg once a day for the last 4 months. Now my legs are back to swelling as much as if I were taking nothing. My blood pressure is good though. Side effects: headaches."

For Edema "I was given this medication to lower my blood pressure. After taking it for one day, my BP went from 165/100 to 122/80. It worked perfectly for that. BUT... I have had headaches and nausea every single day since I started this medication... which was a week ago."

Furosemide for Edema "On 1/30/22, I woke up with ankle and foot swelling and pain out of nowhere. I thought it may have been connected to a full body massage I'd gotten 2 days before that, but at this point, it seems it's not. I'm still having this issue 3.5 weeks later, but now the edema is pitting. I saw my doctor 2 days ago, and she pointed out that my calves are also swollen. She prescribed this medication for me to take twice a day for three days. She's also sending me for an echocardiogram. So far, I've taken one dose, and it may be the last one I take. I've got the absolute worst optical/sinus headache. I've taken my prescription migraine medication, prescription ibuprofen, and 2 over-the-counter sinus pills with no luck. I'm aware headaches are a possible side effect, but I didn't expect it to be this bad. As expected, I'm peeing a lot, but the negatives are outweighing the positives."

Furosemide for Edema "I have taken Lasix for a week to reduce the swelling in my legs. It's working fine and I feel better. The side effects are manageable. I have to pee a lot, and I've had to deal with some headaches."
