Diuretic lasix contains furosemide as active ingredient, therefore it is also known as lasix-furosemide. It has diuretic action due to the blocking re-absorbtion potassium and chlor ions in the ascending part of Henleâ€™s loop.

For the moderate intensity of edema syndrome initial Lasix dosage should be 20-80 mg peroral, or 20-40 mg intravenously or intramuscularly. If the effect is not good enough then the Lasix doses could be increased with another 40 mg peroral, or 20 mg intravenously. Increasing dosage is not allowed earlier than six-eight hours after the initial dose of Lasix oral, and not earlier than two hours after parenteral administration.

Later on the dose of Lasix may be corrected depending on water-electrolytes balance and patientâ€™s condition.
Lasix side effects
The use of big doses of Lasix leads to the decrease of circulating blood volume which in turn leads to the blood thickening, therefore the development of blood clots is possible, and this is quite serious Lasix adverse reactions. One of the most common side effects is development of water-electrolytes impairment which is known as Lasix and metabolic alkolosis especially in presence of diabetes; deficit of sodium, chlor, calcium, potassium; impairment of biochemical characteristics of blood, including increased level of creatinine, cholesterol, triglycerides, uric acid (with acute gout), glucose (especially in presence of diabetes).
There are also a number of possible allergic reactions for different uses of Lasix including so called Lasix rash, dermatitis, itchiness, purpura, and erythema. It even could be anaphylactic shock.
