Furosemide: Brands, Price & Uses in Bangladesh

Furosemide is a loop diuretic ("water pill") with FDA-approved and guideline-supported uses across several conditions:

Established / FDA-approved uses

• Edema associated with congestive heart failure, hepatic cirrhosis (liver disease), and renal disease, including the nephrotic syndrome.
• Acute pulmonary edema (fluid in the lungs), where intravenous Furosemide is used for rapid symptom relief.
• Hypertension (high blood pressure) — Furosemide may be used alone, but is more commonly used as part of combination therapy with other antihypertensive agents, especially in patients who also have edema or reduced kidney function.

Other / adjunct uses

• Adjunct management of hypertensive emergencies (hypertensive crisis) alongside other agents.
• Adjunctive use in acute hypercalcemia (after adequate volume replacement), typically as part of hospital-based management.

The specific dose and form (tablet, oral solution, or injection) depend on the indication and severity — see Dosage and Administration.

Dosing of Furosemide is individualized according to indication, severity, and patient response, using the lowest effective dose. General guidance is summarized below; see Dosage for indication-specific details.

• Furosemide may be given orally (tablet or solution) or by intravenous/intramuscular injection when rapid onset is needed or oral therapy is not feasible (e.g., acute pulmonary edema, hospitalized patients).
• Doses are typically titrated upward at intervals of 6–8 hours until the desired diuretic response is achieved.
• When switching between oral and parenteral routes, dose adjustment may be needed because oral bioavailability is variable (roughly 50–70%).
• Renal and hepatic impairment: no fixed dose-reduction table exists, but doses are generally started low and titrated carefully with close monitoring of renal function and electrolytes; patients with severe renal impairment may require higher individual doses to achieve an adequate diuretic response, under close medical supervision.

Side effects of Furosemide are generally dose-related and most often reflect its diuretic and electrolyte-depleting action.

Common

• Electrolyte disturbances: hypokalemia (low potassium), hyponatremia (low sodium), hypomagnesemia, hypochloremic alkalosis
• Dehydration and volume depletion, dizziness, headache
• Hypotension (low blood pressure), particularly postural (dizziness on standing)
• Increased blood glucose (hyperglycemia) and increased uric acid (hyperuricemia), which may precipitate gout
• Nausea, vomiting, diarrhea, constipation

Less common but serious

• Ototoxicity (tinnitus, hearing loss — usually reversible), especially with rapid IV administration, high doses, or severe renal impairment
• Severe skin reactions (Stevens-Johnson syndrome, toxic epidermal necrolysis) — rare
• Blood disorders (aplastic anemia, thrombocytopenia, leukopenia) — rare
• Pancreatitis, jaundice, hepatic encephalopathy in susceptible patients
• Interstitial nephritis, vasculitis
