Metolazone Overdose: An Overview
Metolazone (
Zaroxolyn®) is a medication used for
controlling high blood pressure and treating water retention (edema). The effects of a metolazone overdose will vary, depending on a number of factors, including how much metolazone was taken and whether it was taken with any other medicines, alcohol, and/or drugs.
If you happen to take too much metolazone, seek immediate medical attention.
