Furosemide Injection cannot be injected intramuscularly and needs to be given by intravenous injection. Furosemide Injection is an injectable medication used to treat heart failure, acute and chronic renal failure, nephritis, and essential hypertension. Its main ingredient is furosemide, which is usually given intravenously as an option after dilution with sodium chloride. Large doses of the drug or long-term use of the drug may lead to the emergence of shock, postural hypotension, hypochloremic alkalosis and other adverse reactions. Adverse reactions such as vomiting, dizziness, abdominal pain, diarrhea, and muscle tonus may also occur. Hearing impairment and tinnitus may occur in some patients, and kidney stones may be triggered if patients have hypercalcemic symptoms. Pregnant women should avoid this drug because it can pass through the placental barrier to the fetus, increasing the chance of miscarriage or fetal death. In addition breastfeeding women should use it under the supervision of a doctor. Use of this drug in elderly patients may cause kidney damage or blood clots, and newborns should be given the drug at longer intervals. Furosemide injection should be used in accordance with medical advice to avoid adverse symptoms.
