white round pill with re 23 on it

Not medical advice: A white, round pill with the imprint RE 23 is 40 milligrams of furosemide. The brand names for the prescription drug are Lasix, Diaqua-2, and Lo-Aqua.

Furosemide is a "loop diuretic (water pill)" that keeps the body from absorbing too much salt. The salt is instead eliminated in your urine. The drug treats edema (fluid retention) in people who suffer from liver disease, a kidney disorder like nephrotic syndrome, or congestive heart failure. It is also used to treat hypertension (high blood pressure).

Less serious side effects: mild skin rash, dizziness, stomach pain, diarrhea, and constipation.

Stop taking furosemide and seek emergency medical attention if you experience hearing loss or ringing in your ears, swelling of the tongue or face, confusion, bruising, fever, or chest pain.

Of interest, a recent examination of the loop drugs toresemide, furosemide, and bumetanide by Yale University revealed that although toresemide is a little more expensive it "lasts longer, is better tolerated, and might be associated with better clinical outcomes compared with the two other available water pills." Of the three, furosemide is the most prescribed drug for the treatment of congestive heart failure.
