Furosemide side effects

Understand potential side effects before starting furosemide. This powerful diuretic, while effective for fluid retention, can cause dehydration if you don’t drink enough water. Monitor your fluid intake carefully; aim for at least eight glasses daily, potentially more, depending on your individual needs and the prescribed dosage.

Beyond dehydration, be aware of potential electrolyte imbalances. Furosemide can deplete potassium, sodium, and magnesium. Low potassium, in particular, may cause muscle weakness or irregular heartbeat. Regular blood tests can monitor these levels, allowing for timely adjustments to your medication or dietary intake. Your doctor can recommend specific foods rich in these electrolytes or suggest supplements.

Some individuals experience dizziness or lightheadedness. This is often related to sudden blood pressure drops. Rise slowly from a sitting or lying position to minimize this risk. Report any persistent dizziness or fainting episodes immediately to your physician. They can adjust your medication or recommend additional strategies to manage blood pressure.

Less common but still significant side effects include hearing loss (temporary or permanent), skin rashes, and gastrointestinal upset (such as nausea and diarrhea). Note any unusual symptoms and consult your doctor promptly if you experience any of these or other concerning side effects. Remember, this information isn’t a replacement for professional medical advice; always speak with your doctor about your individual risk profile and management of any side effects.

Furosemide Side Effects: A Detailed Guide
