While taking spironolactone, avoid taking potassium supplements or following a diet rich in potassium(containing foods like bananas, spinach, and potatoes). High potassium levels in the body can cause hyperkalemia.
Also, avoid eating foods that are high in salts, such as salted meat, pickles, and pizza. Inform your healthcare provider of all medicines you take, including over-the-counter medications and herbal supplements.
Spironolactone can interact with alcohol which may worsen side effects such as dizziness, so you should lessen or avoid consuming alcohol.
