Lasix (Furosemide)


What is Lasix

Lasix is a potent "water" pill, used to eliminate excess water and salt retained by the body. Salt, water and other small molecules are filtered through the blood, into the tubules of the kidney, but most of these are reabsorbed in the bloodstream, before being released as urine. Generic Furosemide blocks this re-absorption, helping the body to get rid of the waste through urine.

How to use Medicine

This diuretic is used in treating edema [fluid retention] in those individuals who suffer from congestive heart failure, hypertension, nephrotic syndrome, cirrhosis of the liver, cerebral/pulmonary edema, severe hypercalcemia, or when they have problems with their lymph nodes.

The medicine can be taken by mouth or injected. It takes an hour to take full effect if taken orally. When injected, it takes just 5 minutes for results to peak. The duration of the diuresis normally lasts 6-8 hours. This loop diuretic provides quick relief, but the medicine should be taken for the full term.

The pills, available in 3 strengths, may be taken once or twice a day – as prescribed by the doctor, who will decide upon the dose taking the overall medical condition into account. When administered to children, individual weight is also considered while prescribing the dose.

Before you take the medication make sure you have informed your healthcare provider about the following conditions, if any: inability to urinate, cirrhosis or any other liver disease; kidney disease, gout, lupus, electrolyte imbalance, high level of cholesterol or triglycerides, sulfa drug allergy, bladder obstruction, enlarged prostate, diabetes, etc. Make sure you have reported a recent MRI or contrast dye injections, which may harm the kidneys.
Furosemide can make you urinate more frequently, and there is a chance of fast dehydration, so follow the instructions about the use of enough potassium and salt.

Missed Dose of Lasix

Consult your doctor if you miss a dose. It is usually recommended that if you are taking 2 doses every day and miss one, then you can take the missed dose only if 12 hours are still left for the next dose, but don't double your dose, as an overdose may cause dehydration due to excess depletion of water and salts.

Side-effects of Lasix

  • Dizziness
