This medication is used alone or in combination with other medicines to treat high blood pressure. It works by blocking a chemical (aldosterone) in your body which in turn lowers the amount of sodium and water the body retains. Lowering high blood pressure helps prevent strokes, heart attacks and kidney problems. It is also used to treat congestive heart failure following a heart attack.
Take this medication by mouth, usually once or twice daily, with or without food, or as directed by your doctor. Use this medication regularly in order to get the most benefit from it. Remember to use it at the same time(s) each day.
The dosage is based on your medical condition (high blood pressure, heart failure), response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).
It may take up to 4 weeks for this medication to fully affect your blood pressure.
It is important to continue taking this medication even if you feel well. Most people with high blood pressure do not feel sick.
