  • What is Lasix

    Lasix (furosemide) is in a class of medications called diuretics or "water pills". It helps you make more urine and to lose salt and excess water from your body. This medicine is used to treat high blood pressure, and edema or swelling from heart, kidney or liver disease.

  • How does lasix work

    In the kidneys, salt, water, and other small molecules normally are filtered out of the blood and into the tubules of the kidney. The filtered fluid ultimately becomes urine. Most of the sodium, chloride and water that is filtered out of the blood is reabsorbed into the blood before the filtered fluid becomes urine and is eliminated from the body. Lasix works by blocking the absorption of sodium, chloride, and water from the filtered fluid in the kidney tubules, causing a profound increase in the output of urine.

  • Lasix dosage

    Your doctor will decide what dose you should take based on your condition and medical history. Never stop taking Lasix or alter your dose without your doctor's approval.

    Adults who have fluid retention problems will typically begin with a single dose of 20 milligrams to 80 mg. The dose in children will vary based on what your doctor deems appropriate.

    Adults who have high blood pressure often begin with 40 mg, twice per day. The dosage may be adjusted for elderly patients.

  • How does diamox work

    An increase in pressure within your eye can lead to damage to the optic nerve at the back of your eye. When this occurs it is called glaucoma. Glaucoma can lead to a loss of vision if it is not treated. Treatment with Diamox helps to reduce eye pressure, and this helps to prevent further eye damage. Diamox works by blocking the action of an enzyme called carbonic anhydrase. Blocking this enzyme reduces the amount of fluid (called aqueous humour) that you make in the front part of your eye, and this helps to lower the pressure within your eye.

  • Diamox dosage

    Glaucoma: the recommended dose range for Diamox is 250 mg-1000mg/day.

    Acute Mountain Sickness: the recommended dose range for Diamox is 500 mg-1000mg/day.

    Edema: recommended dosage is 250 to 375 mg of acetazolamide once a day for one or two days, alternating with a day of rest.

Questions & Answers

Where to buy lasix or diamox over the counter in the U.S.?

You can not buy lasix and diamox without prescription in the US, Canada, UK and most other countries in the world. You need to get a prescription for diuretics from your doctor before being able to access the meds. If you have a prescription, Walgreens, CVS, Walmart or any other online pharmacy will sell drugs for you.



My wife (52 years old) started furosemide 20 mg twice a day for fluid retention. It has helped with that, but has caused hearing loss in both ears. She has been told to stop for two weeks and see her doctor for blood work afterwards.


I have been taking Lasix for a long time due to hypertension. I have a lot of problems with swollen hands, especially in the mornings. I am very sensitive to salt. I have to be careful taking it when I am working because for the first few hours I am there, I usually have to go to the restroom several times, but then it levels off in the afternoon. I also started Wellbutrin which also has a diuretic effect, so taking both of them sometimes gets a little out of hand!

I have been using Lasix in combination with Hydrochlorothiazide for 6 months for pitting edema/hypertension and it's 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.


I have been recently diagnosed with the disease called BIH which occurs mostly in women and very young children and currently taking Diamox with annoying side effects such as pins and needles in feet, hands and lips which can last up to 2 hours at a time and be painful. I wake every night with interrupted sleep with a headache or temperature! I have been turned off a lot of food but mainly fizzy drinks.

The dose of acetazolamide for prophylaxis is 125-250 mg twice a day starting 24 hours before ascent, and discontinuing after the second or third night at the maximum altitude (or with descent if that occurs earlier). Sustained release acetazolamide, 500 mg, is also available and may be taken once per day instead of the shorter acting form, though side effects will be more prominent with this dose.
