Furosemide is a loop diuretic causing fast and short diuresis. It possesses natriuretic effect and also decreases levels of Cl- in blood, increases excretion of K+, Ca2+, Mg2+. Penetrating into a renal tubule in ascending thick limb of Henle's loop it blocks re-absorption of Na+ and Cl-. Due to increased excretion of Na+ secondary intensified excretion of water occurs and as well as increased secretion of K+ in distal part of the renal tubule. Simultaneously excretion of Ca2+ and Mg2+ increases. Furosemide is used to treat edema syndrome in patients with chronic heart failure (degree II and III), cirrhosis, diseases of kidneys, acute heart failure (pulmonary edema), brain edema, hypertensive crisis, arterial hypertension and others.
Dosage and direction
Take exactly as it was prescribed by your doctor.
Before using Furosemide, consult your doctor if you suffer from kidney disease, liver disease, gout, lupus, diabetes, or an allergy to sulfa drugs. Avoid becoming dehydrated as Furosemide makes you urinate more often. Do not stop taking the drug even if you feel fine as high blood pressure often has no symptoms. Avoid taking the drug if you are pregnant or breastfeeding.
Hypersensitivity, acute kidney failure with anuria, severe liver failure, liver coma and precoma, stenois of urethra, acute glomerulonephritis, urinary tract obstruction, precoma, hyperglycemic coma, gout, arterial hypotension, heart attack, pancreatitis and others.
Possible side effect
Contact your physician for medical attention if you have signs of allergy or any following conditions: dry mouth, thirst, nausea, vomiting; weakness, drowsiness, restless, or light-headed, fast or uneven heartbeat, muscle pain, less than usual urination or absence of urination, easy bruising or bleeding, red blistering skin rash, hair loss.
Hearing damage may occur if Furosemide is administered with aminoglycoside antibiotics (gentamicin and others) or Edecrin - another diuretic. Concomitant use of Furosemide and aspirin may cause high blood levels of aspirin and aspirin toxicity. Furosemide is able to reduce excretion of lithium by the kidneys. Sucralfate (Carafate) reduces the action of Furosemide. Intake of Ingestion of Furosemide and Sucralfate should be separated by two hours.
The medication is sometimes administered for single use so you will not need a dosing schedule. If you take Furosemide regularly and forgot to take a dose take it as soon as you remember. Skip the missed dose if it is almost time for the next intake. Resume your regular schedule. Do not compensate the missed dose by taking an extra one.
In case of loss of appetite, ringing in ears, severe weakness, dizziness, confusion, lightheadedness, or fainting, seek for immediate doctor's attention.
Keep away from children at room temperature in a dry and dark place.

Lasix, of course, is not a universal remedy, but it came for help when I was in a critical state with very high blood pressure. Anyhow I try not to take it very often. I buy it on the website the site from the trusted seller site.
jesus angel sastre martin (15-Jan-2020)
I am afraid of many side effects, that’s why I am taking Lasix 40, and not a higher dosage. It is a good medicine.
Derek Price (14-Jan-2020)
Before taking Lasix 100, I consulted my physician. I try to eat healthy food and not to provoke the appearance of edema, but sometimes it happens to me. The doctor said I can take Lasix 100 in cases when I feel really bad. Lazix always saves me!!
Sammy Edlin (13-Jan-2020)
I have problems with high blood pressure and have severe cardiac failure. I take Lasix 100 mg as prescribed by my doctor, but of course I take it with caution and try not to take it too often. Very good and effective pills.
Chema Giménez Jarné (13-Jan-2020)
I also buy it from the same seller. They send it to me quickly. I always keep these pills at home, and, as I have problems with lungs, I have to take it regularly.
Romain Pedrero (10-Jan-2020)
I order it for myself here the site,and I take it because of the edematous syndrome of a liver disease. But my doctor also prescribed magnesium and calcium. Lasix is the best for me.
Eric Lockard (07-Jan-2020)
I took it for my mother, ordered Lasix online and the company sent it quickly. I trust this seller site, and this is not the first time I buy pills from them. As for me, I take Lasix only from time to time, but it helps very fast!
Mike Miles (06-Jan-2020)
I always measure my blood pressure, because the medicine can reduce it very fast, that’s why sometimes you take Lasix 40 mg, and sometimes it’s better for me to take Lasix 100.
Caio Campos (05-Jan-2020)
I order Lasix online and always get it quickly delivered. One or two pills on the empty stomach – and no morning edemas! Very good pills!

Daymonds Jesus Rodríguez Marambii (03-Jan-2020)
I was taking Lazix in the summer when it was hot. First I wanted to buy diuretic tea at the drugstore, but then I ordered Lasix and the seller delivered it to me very fast, so I thought it would be the best solution for my problem. On the first day of taking I was running to the toilet the whole day as if I had cystitis. But then I decided to go to consult a doctor anyhow.
marlyn miller (03-Jan-2020)
It is one of the strongest and the most effective diuretics nowadays. I wouldn’t take higher dosages if I didn’t try the smallest one. My mom also takes 40 mg, as far as I remember.
CARMELO BERENGUER (02-Jan-2020)
The dosage of Lasix 100, for me is a bit high. The normal dosage for me is 40 mg, but I sometimes take Lasix 100, it is like an emergency aid for my hypertonic crisis.
GERARD LANDAT (02-Jan-2020)
My mother took it because of high blood pressure problems. This is the only medicine that helps immediately. Her doctor prescribed it to her and I ordered it here the site for her. As I know, it’s not recommended to take it without potassium.
Heather Robinson (01-Jan-2020)
The doctor prescribed Lasix 40 mg to my mother. She took it to reduce edema on legs. In such concentration the action of the medicine is sparing.
paul Young (31-Dec-2019)
This is the best medicine to reduce my blood pressure. But it is an emergency measure, which makes you lose potassium, but anyhow I always keep it at home just in case. I bought Lasix herethe site.
Karl-Heinz Müller (29-Dec-2019)
I use Lasix very often. I have poor adrenal glands and I am always swelling, especially in the summer. Especially when the weather is very hot and you're always thirsty. I can drink two -three liters of water, and never go to the toilet, so in these cases I go to use diuretics, and Lazix 100mg is my first aid in such situations. I used to take Lasix 40, but for me it’s not enough.
BD Bil Erik Sönnerfors (25-Dec-2019)
My dad orders Lasix here the site. He says this is a trusted company, and I always buy some healthcare stuff from this seller site. Lasix is the only diuretic which helps him.
francisco pinto (25-Dec-2019)
My mother takes Lasix 40 and not other higher dosages, as there are many contraindication for this product. It is 100 % effective, and you can see immediate results, but she takes it with caution.
Florian Zurlinden (25-Dec-2019)
When I had serious problems with my heart, and, as a result, I had high blood pressure and awesome edema on my legs, I took Lasix, and it seemed that it was the only thing that could help. I also buy it on the website the site, but I think your doctor should prescribe this medicine before you decide to take it.
Mario Valentini (23-Dec-2019)
Lasix is really a strong diuretic. It helps my mother to cope with her gummy hands and feet because of her heart problems. After approx 30 minutes she starts to go to the toilet and it makes her feel better. I order this medicine online for her and get it delivered quickly by the company.
Claire Nagle (22-Dec-2019)
I came to the conclusion that the cause of edema should be determined by your doctor, and Lasix should be taken only in emergency cases and according to indications. Anyhow, I also ordered Lasix online and got it quickly delivered by the certified medical company. Good and effective pills!
Davide Farina (21-Dec-2019)
These pills are not addictive. I only take Lasix from time to time. The dosage of Lasix 100mg of course, is high, but for my situation with very high blood pressure this is the best way out. Before I was taking the dosage of 40 or 50 mg, and I must say that these pills help and reduce my blood pressure very quickly!
Dennis Justis (21-Dec-2019)
Very good diuretic. I take it only from a certified seller site the site.
Alphonso McPherson (19-Dec-2019)
A good diuretic that rapidly removes excess fluid from the body. I buy it on the site the site in order to get rid of edema from ankles and hands.
Fernando Prats Moyano (19-Dec-2019)
I prefer to take Lasix 40mg than 100mg. To reduce high blood pressure is enough, I suppose. It always helps me quickly.
Maurice Giese (18-Dec-2019)
I suffer from hypertension for about 20 years. When I was 30, I began taking pills every day to normalize pressure as it was prescribed by my doctor. Unfortunately, sometimes because of pressure jumps I have problems with the heart and gasping. In such cases I use Lasix, it helps me a lot. I usually take in advance to have it with me in case I need it. The distribution company the site.always sends it without delay.
Yoann Reichmuth (17-Dec-2019)
It should be noted that the pills are not expensive and they are very effective. I would take it only from a trusted seller site, so always I ordered it here the site.
virgile tripet (16-Dec-2019)
I buy Lasix for my granny, and she takes it on a regular basis, but not much, as I know, she takes it only twice a week. She says this is the only medicine that helps! The online sale suits me. I always get it on time and without any delay.
Nicholas Chase (15-Dec-2019)
100% effective pills, and I use it only when it’s necessary. For example, if I notice the swelling of my eyes in the morning, I immediately take Lasix. I buy it on the site and keep it at home for such situations.
Raul Colon (14-Dec-2019)
I was worried about the baggy lower eyelids. May be because of the wrong regime or something else, I don’t know.., irregular meals, stress - from all this, I think.. My doctor prescribed Lasix and potassium. I bought Lasix on the website and got it shipped to me very fast. But you cannot take it for a very long time.
Ryan Parsons (13-Dec-2019)
I was concerned about side effects, so I consulted my doctor, and he said to start with Lasix 40 mg dosage. The medicine is very good and it helps me to reduce blood pressure very quickly.
Alexandre Andrade (13-Dec-2019)
Lasix is a medicine that I use in emergency cases, as when you take it, you get short of potassium in your body at the same time. Anyhow, I buy it here the site, and also take it from time to time because of my high blood pressure. It helps immediately!
larry martin (12-Dec-2019)
It’s a very good and helpful product. Everyone who suffers from edema knows it for sure. I also order it online, and the seller site supplies me with it, sending it very quickly.
Brian Mackie (10-Dec-2019)
100% effective diuretic. I buy it from the same company on the site the site.
Amelie Kazadila (09-Dec-2019)
It’s a very old and famous medicine, my favorite diuretic... My grandmother still sometimes takes it to get rid of water in her ankles. I order it for her and for myself, and the seller always sends it quickly.
Melissa Serna (07-Dec-2019)
I buy Lasix 40 only from the trusted seller site, who ships original product and always delivers it on time. I take this medicine as I have edema from a kidney failure.
belaid zourdani (06-Dec-2019)
My mother takes Lasix to reduce her high blood pressure. She takes one pill in the morning, and during 2-3 hours she goes to a toilet many times. I order it for her from the trusted seller site. They always send the medicine to us very quickly.
PAVLOS MAROUDAS (06-Dec-2019)
Lasix 100 is a serious dosage. I got it prescribed by my doctor. I take it but not very often, it’s an excellent stuff to reduce my high blood pressure. I also try to take calcium and magnesium.
Claus Juul (02-Dec-2019)
Excellent diuretic! I took it when I was pregnant, as my doctor prescribed, but also the smallest 40 mg dosage. I think people with serious diseases which cause edema can take 50 mg and even more at a time.
Giles Macdonalds (02-Oct-2015)
I have increased blood pressure and often come by to order Lasix 40 mg. This pharmacy works great for me: it's fully licensed, has affordable prices, friendly and efficient support staff, as well as convenient payment methods. They never gave me a single reason to doubt their integrity and professionalism, so I will remain their loyal customer for as long as I need to be taking Lasix 40 mg.
Flora Ferrari (29-Sep-2015)
Was started on 80 mg Lasix but then was recommended to take half the dose, because it was enough. I purchased Lasix 40 mg to have enough for a few months to treat fluid retention in my legs. I come in for tests every one and then, my doctor says it's working very well. I feel much better and can walk longer distances without any of the discomfort.
Lenard Hood (27-Sep-2015)
I recommend this pharmacy if you are still deciding where to order Lasix 100 mg. I ordered mine here and was happy with everything, the service and the prices. They give you very nice deals when you order in bulk, so you may take than into consideration. The quality of their drugs is always very good, Lasix 100 mg works great for me and causes no side effects.
Noah Richardson (26-Sep-2015)
Lasix 40 mg is a great drug that does the job it's supposed to do. My doctor told me that I should replenish my potassium though, because Lasix can decrease its amounts, it may be a potassium pill or foods high in potassium (like bananas). It works great, cannot complain about anything really. I ordered it online, so the price was also pretty good.
Shana Morris (07-Sep-2015)
I ordered from this pharmacy only once, but it already managed to impress me. My order arrived sooner than I expected, they delivered Lasix 40 mg to my home in just four days. I was not in a hurry because I was only starting the treatment, but it's nice to know they have your back in case you do need those pills asap.
Simon Bradford (04-Sep-2015)
I decided to take Lasix 40 mg to treat my edema, it worked well for me the last time I took it. My insurance does not cover it. It's pretty basic, so I went online and found this pharmacy. I was impressed with the high quality of the drugs they offer (bought some other ones I also needed) and their efficient customer service. Will definitely be coming back for more in future.
Mark Peters (30-Aug-2015)
This nice pharmacy is where I come when I need to buy more Lasix 40 mg. I'm taking it for high blood pressure, so I'm in for the long haul. I'm glad to have this pharmacy at my disposal ready to accept my order any time of the day, because otherwise the cost of my treatment would be impossible to afford. This pharmacy sells high quality drugs at low prices, and that's all I really want.
Jack Montgomery (26-Aug-2015)
Very efficient drug and no side effects that could be mentioned. I take Lasix 100 mg once every day, not sure how long I will have to be taking it for, it's up to my doctor. I decided to order it online because it's much cheaper and more convenient. So far this drug has been working well for me and I have no complaints.
Leslie Ball (18-Aug-2015)
This pharmacy is famous for its fast delivery, so I was expecting my Lasix 40 mg to arrive in a week. Imagine my surprise when they delivered it in five days! It's amazing how fast you can get your order from across the ocean, I'm deeply impressed and will be recommending this place to everyone I know.
Matthias Trommler (18-Aug-2015)
With online pharmacies, the most irritating thing is their delivery. This pharmacy is nothing like that though, they deliver quite fast and without any delays. I ordered Lasix 100 mg twice already, every time it took them five days to deliver. It's very convenient and not at all costly, which is always nice.
Joshua Chandler (16-Aug-2015)
Amazingly fast delivery and reasonable prices are main reasons why I love this pharmacy. I mean, having high blood pressure is no fun, but it's nice to know you can order Lasix 40 mg today and expect it to arrive in only a few days. This pharmacy works very hard to make its customers happy and I do appreciate it.
Michael Mason (12-Aug-2015)
I ordered Lasix 100 mg at this pharmacy last week and started taking it as soon as it arrived. It removed water quickly and very effectively, the next day everything was even better. This pharmacy is great: they suggested taking a potassium supplement along with Lasix to make sure my potassium levels are normal. It's nice that they care so much about their patients.
Harold Cunningham (09-Aug-2015)
This pharmacy is where I go whenever I need any drug. The latest one I ordered was Lasix 100 mg, as I had terrible fluid retention. This pharmacy sells only best quality drugs which is why I have no fluid retention anymore. The treatment cost me nearly nothing: with the prices this pharmacy has, you can afford treatment for any condition, even if you have to take some drug for the rest of your life.
George Walker (06-Aug-2015)
I was taking Lasix 40 mg to treat ankle swelling due to fluid retention. I remember not believing my eyes when I saw my ankle in the morning - the swelling was almost gone, in just a day! The only inconvenience was that it made me go to the bathroom more often than I was prepared to, but you get used to it. Lasix works better than other diuretics, I tried other ones before it and the results were insignificant.
Robert Webb (04-Aug-2015)
I began taking Lasix 100 mg because it's the safest loop diuretic, and among the most efficient ones too. It started working right away, I noticed a significant improvement after just one day of treatment. My hands and feet had been swollen to the maximum before that, so that was big progress for me! I'd tried other medications to reduce swelling before, but none of them worked as well as Lasix.
Victor Newton (26-Jul-2015)
I've been taking Lasix 100 mg for three weeks. So far it's been great, and if my doctor says it's okay, I will stop taking it and hope the swelling will not come back. From reading other people's reviews I know that Lasix 100 mg works much better than the 40 mg dosage, which is logical, and yet only a very small number of them have any side effects at all.
Barnaby Cummings (20-Jul-2015)
I'm taking Lasix 40 mg once a day for water retention. My doctor said it's the safest loop diuretic to be taking, so it's the one I ordered online. At the beginning I was taking the 80 mg dose but was tired a bit more than usual. This side effect went away when I stated taking a lower dose, Lasix 40 mg. It works fine for me, no side effects or anything. The symptoms are improving every day, so it's great I decided to go for this medicine.
Paul Potter (09-Jul-2015)
I've been taking Lasix 100 mg for a few months to treat high blood pressure. My doctor said this dosage had to work, but before that I was taking 40 mg. I take it once a day in the morning, with a glass of water. So far haven't had any side effects, don't know if I got lucky or it's just the way it usually is. The drug works well for me, its quality is excellent.
Emory Beasley (03-Jul-2015)
I started taking Lasix 100 mg after the 40 mg dose did not really work for me. So far I am happy with that dosage, especially since I did not get any side effects. This was my worry because of the higher dosage. It lessens the fluid retention significantly; I'm feeling much better and will soon be having lab tests done to see how much progress I made.
Joseph Carroll (17-Jun-2015)
I came to this pharmacy looking for cheap Lasix 100 mg with fast delivery that would not cost me too much either. At a standard price, their delivery is very fast, my order arrived even sooner than I was expecting it. I quite enjoyed placing my order with this pharmacy, they treat you real nice and help you whenever you need help.
