There are three types of diuretic medications useful in the treatment of hypertension: hydrochlorothiazide and other thiazides, furosemide (Lasix), and spironolactone (Aldactone). To date, furosemide has demonstrated no sexual side effects. However, there is a definite increase in impotence among men treated with thiazides.

Spironolactone has well-documented antiandrogen (anti-male hormone) properties. Men treated with spironolactone are incapable of appreciating the full impact of their own testosterone. This may explain why decreased libido is the single most common sexual side effect reported by them. Despite its side effects, spironolactone has not been stricken from the pharmacologic registry. This medication distinguishes itself from other diuretics by its ability to allow the body to flush out excess sodium while capturing potassium. All the other diuretic medications create a potassium deficiency, a condition that can cause irregular heart rhythms, constipation, muscle cramps, and — as if this were not enough — impotence.

Furosemide Diuretic

buy LasixIndications
Edema of cardiac, hepatic, or renal origin; hypertension; pulmonary and cerebral edema; usually reserved for patients who do not respond to thiazide diuretics or in whom a rapid onset of diuresis is desired


Diuresis: adult: 20 to 40 mg intramuscularly or intravenously as a single dose. Intravenous doses should be injected slowly over 1 to 2 minutes. Additional doses of 20 mg greater than the previous dose may be administered every 2 hours until desired response is obtained. For intravenous bolus injections, do not exceed 1 g/day administered over 30 minutes. Acute pulmonary edema: 40 mg intravenously initially; may repeat in 1 hour with 80 mg if necessary. Children: intramuscular or intravenous: 1 mg/kg single dose initially, increasing by 1 mg/kg every 2 hours or more until desired response is obtained or to a maximum of 6 mg/kg/day.
Dosage fanny, tablets: 20,40,80 mg; injection: 10 mg/mL; oral solutions: 10 mg/mL and 40 mg/5 mL.

Onset and duration

Onset: intravenous: onset of diuresis usually occurs in 5 minutes. Duration: 2 hours. Elimination half-life: widely variable; normal is Vi to 1 hour, but a period of 11 to 20 hours has been reported in patients with hepatic or renal insufficiency.

Adverse effects

Dehydration, hypotension, hypochloremic alkalosis, hypokalemia, hypo-magnesemia, hyperglycemia, hyperuricemia
Ototoxicity has been reported with too rapid intravenous injection of large doses. Rarely reported are thrombocytopenia, neutropenia, jaundice, pancreatitis, and a variety of skin reactions.

Precautions and contraindications

Furosemide is contra-indicated in anuria (except for a single dose in acute anuria) and pregnancy. Use it with caution in patients with severe or progressive renal disease and hepatic disease. Discontinue it if renal function worsens. Use caution in patients who are allergic to sulfonamides and patients with severe electrolyte imbalance.

Anesthetic considerations

Monitor electrolytes and fluid balance. Administer furosemide carefully in patients taking digitalis. It may be associated with enhancement of nondepolarizing neuromuscular blocking drugs.

The initial form of therapy for congestive heart failure is to relieve congestion with a diuretic (water pill) called Furoscmide, more commonly known as Lasix. This medication allows the kidneys to excrete excess salt and water. Diuretics are critical in the improvement of symptoms including shortness of breath, inability to lie down, and leg swelling This medication, however, has no mortality benefit and can cause harm over long-term use sodium, magnesium, potassium, and other salts are lost in urine Patients can then become dehydrated and develop renal dysfunction because the kidneys are starved of blood flow When a patient is dehydrated from Lasix they will feel short of breath due to a ventilation perfusion miss-match. Lasix is a medicine heart failure patients always need to keep nearby because of possible dietary indiscretions that occur especially around holiday celebrations where excess sail is consumed. The heart failure patient has a difficult time excreting salt, thus resulting in an accumulation of salt within all body fluids over time. The salt will hide in all liquid components of the body including inside cells The distribution is everywhere so it is difficult to detect. In order to maintain electrolyte balance, the body swells with fluid to keep its electrolyte levels normal     Lasix (Furosemide) is a diuretic typically prescribed for short-term use.
