Should I Avoid Certain Food or Medications While on a Diuretic?
Diuretics are generally prescribed in combination with an ACE inhibitor, digoxin, and a beta-blocker. If you experience an increase in side effects after taking your medications together, contact your doctor. You may need to change the times you are taking each drug.
Potassium-sparing diuretics increase the effects of digoxin and lithium. They may increase your body's potassium level if taken with ACE inhibitors.
Before a diuretic is prescribed, tell your doctor if you are taking: other drugs for high blood pressure, digoxin, Indocin, lithium, probenecid, or corticosteroids (prednisone).
Before this drug is prescribed, tell your doctor if you have diabetes, kidney disease, liver disease, or gout.
Follow your doctor's dietary advice, which may include: following a low-salt diet, taking a potassium supplement, or including high-potassium foods (such as bananas and orange juice) in your diet. Note: some types of diuretics cause your body to lose potassium. If you are taking a "potassium-sparing" diuretic, your doctor may want you to avoid potassium-rich foods, salt substitutes, low-salt milk, and other dietary sources of potassium. If you are not sure what type of diuretic you are taking, ask your doctor.

While taking this drug, have your blood pressure and kidney function tested regularly, as advised by your doctor.
Keep all appointments with your doctor and the lab so that your response to this drug can be monitored.
Alcohol and sleep aids may increase the side effects of this drug and should be avoided.
