Metolazone (Zaroxylin)

Dosage
Doses range from 2.5 mg to 10 mg once a day.

Action
In addition to the diuretic functions described above, Zaroxylin also lowers blood pressure directly. The way the drug does this is unknown.

Side Effects

• Many diuretics can cause a decrease of potassium in your blood. This happens because the diuretics cause the kidneys to filter the potassium out of the blood and into your urine. Having a low potassium level can cause muscle cramping, muscle weakness, and an irregular pulse rate.
• If the diuretic causes the kidneys to make too much urine, you may become dehydrated, have low blood pressure and dizziness, or have fainting and dry mouth as a result of losing too much fluid.
• With high doses of a diuretic, you may have ringing in your ears or deafness may even occur.
