Frusemide (also known as furosemide) 2 ml injection is primarily used as a diuretic to treat fluid retention (edema) caused by congestive heart failure, liver disease (such as cirrhosis), kidney disease including nephrotic syndrome, and acute pulmonary edema. It helps remove excess fluid from the body by increasing urine production through action in the kidneys. It is also used to manage high blood pressure (hypertension), especially in emergency situations like hypertensive crisis or acute pulmonary edema. The injection form is typically administered intravenously (IV) or intramuscularly (IM) and is reserved for patients who cannot take oral medication or require rapid onset of action. For adults, the usual dose is between 20 mg to 40 mg per injection (contained in a 2 ml ampoule), with repeat doses possible depending on clinical response. It can be given as a single dose or repeated doses as needed. In emergencies like pulmonary edema, a higher dose (up to 80 mg slow IV injection) may be given if initial response is inadequate. After stabilization, treatment is usually switched to oral medication. Frusemide injection should be carefully monitored for side effects including electrolyte imbalances like low potassium (hypokalemia), dehydration, dizziness, and others. It is contraindicated in some types of edema such as those caused by kwashiorkor and hepatic encephalopathy and should be avoided in pregnancy for hypertension. The injection is typically given in medical settings by healthcare professionals.
