Furosemide

Furosemide is a strong diuretic, commonly known as a 'water pill,' used to treat conditions such as high blood pressure and edema (fluid retention) caused by various medical problems, including heart, kidney, and liver disease[1][2][4]. It works by increasing the amount of urine produced by the kidneys, which helps to reduce swelling and lower blood pressure[1][2][4].

Important Warning

Furosemide may cause dehydration and electrolyte imbalance, so it is crucial to take it exactly as directed by a doctor. If any of the following symptoms occur, immediate medical attention is necessary: decreased urination, dry mouth, thirst, nausea, vomiting, weakness, drowsiness, confusion, muscle pain or cramps, or rapid or pounding heartbeats[1].

Uses

Furosemide is used alone or in combination with other medications to treat high blood pressure and edema. It is particularly effective in reducing swelling caused by heart failure, liver disease, or kidney disease[1][2][4].

How to Take

Furosemide comes in tablet and liquid forms and is usually taken once or twice a day. The dosage and frequency of administration may vary depending on the condition being treated and the individual's response to the medication[1][2][4].

Special Dietary Instructions

If a doctor prescribes a low-salt or low-sodium diet, or recommends eating or drinking increased amounts of potassium-rich foods, it is essential to follow these instructions carefully[1].

Interactions with Other Medications

Furosemide may interact with certain medications, such as sucralfate, cyclosporine, digoxin, ethacrynic acid, indomethacin, laxatives, lithium, medications for diabetes, high blood pressure, and pain, methotrexate, probenecid, and phenytoin. It is crucial to inform a doctor about all medications being taken to avoid potential interactions[1][2].

Side Effects

Common side effects of furosemide include nausea or vomiting, diarrhea, constipation, stomach cramping, dizziness, headache, blurred vision, itching or rash, and increased urination[3]. Serious side effects may include excessive loss of water and electrolytes, low levels of thyroid hormones, pancreatitis, liver damage, and hearing loss or ringing in the ears[3].

Precautions

Furosemide may increase the risk of dehydration, especially in older adults, and may affect blood sugar levels in people with diabetes. It may also cause dizziness, blurred vision, and sensitivity to sunlight[3][5].
