Blood Pressure Home > Oretic

Oretic is commonly prescribed to control high blood pressure and treat water retention. The diuretic works by increasing the amount of salt and water removed from the blood, which causes a decrease in blood volume and a drop in blood pressure. The medication comes in tablet and capsule form, and is typically taken once a day. Possible side effects include nausea, electrolyte imbalances, dizziness, or vomiting.
