What is Furosemide (Lasix) and How to Take It

Furosemide is a prescription drug for treating high blood pressure and edema (water retention). It is available as Lasix, Furoscix, Diaqua-2, and Lo-Aqua in the market. Furosemide belongs to the diuretic class of medication. Some other medications from this class include Bumetanide, Torsemide, and Ethacrynic acid. Due to its safety profile and effectiveness, Furosemide is not a first-line of treatment in patients with hypertension; however, it is often prescribed for edema due to congestive heart failure, liver cirrhosis, and renal disease.

Furosemide is a loop diuretic that is indicated for use in edema and high blood pressure. Furosemide acts on the kidney to increase the excretion of urine from the kidney by inhibiting electrolyte reabsorption. This helps in excessive water loss from the body leading to less fluid retention in edema. Low levels of water content and lower electrolyte reabsorption also help manage low blood pressure.

Furosemide is an oral medication available as a tablet, in varying dosage strengths of 20 mg, 40 mg, and 500 mg It is vital to take Furosemide online prescription as directed.

The tablet can be taken once a day, with or without food, as it does not upset the stomach if taken with food. Take it in the morning time and avoid taking it in the later hours of the day as it may cause sleep disturbances.

What happens if I miss a dose of Lasix?
