Spironolactone is used to treat high blood pressure, edema (fluid retention and swelling) and heart failure. It works by blocking the hormone aldosterone in the kidneys, which causes salt and water to be retained. This allows more sodium and fluid to be eliminated in the urine, while reducing the loss of potassium.
Spironolactone can cause dehydration, which is why it’s important to drink plenty of fluids while taking this medication. You should aim for eight glasses of water a day, or more if your doctor recommends it. You can also help prevent dehydration by eating foods that are high in water content, such as watermelon, lettuce, celery, and cucumbers. If drinking water isn’t easy for you, Buoy hydration drops can be an effortless way to get the recommended amount of water while taking spironolactone.
Drinking plenty of fluids while taking spironolactone can help reduce the side effects of this medication, such as dizziness and tiredness. However, you should not drink alcohol while on spironolactone as this can lead to dehydration.
