Downsides

If you are between the ages of 18 and 60, do not take any other medications, and have no other medical conditions, you are more likely to experience the following side effects:

• Standing dizziness, gastrointestinal disturbances, changes in blood counts, and changes in cholesterol levels or liver function are all possible.
• Furosemide has a powerful effect. Use can result in electrolyte depletion, which can cause side effects like muscle cramps and irregular heartbeats; the risk is higher in people who have a low salt intake or are taking certain medications.
• Tinnitus as well as reversible or irreversible hearing loss have been reported. Higher doses, injectable furosemide, severe renal impairment, low protein levels, and concomitant therapy with other drugs that are also toxic to the ears increase the risk.
• Blood glucose levels may rise and laboratory test results may be affected.
• Furosemide's initial diuretic effect may not be as effective in older people.
• Some people may not be able to use it, including those with cirrhosis of the liver or ascites, kidney disease, who are already electrolyte depleted, or who are dehydrated.
• Other medications that lower blood pressure or potassium levels, such as lithium, corticosteroids, digoxin, phenytoin, and methotrexate, may interact with it.

Note: People over the age of 65, children, people with certain medical conditions (such as liver or kidney disease, heart disease, diabetes, seizures), or people who take other medications are more likely to experience a broader range of side effects.
