For heart failure, spironolactone helps prevent scarring and remodeling in the heart and improves heart function. Like all diuretics, however, spironolactone may not be right for everyone.

As a result, taking spironolactone with food is like taking a higher dose. That\u2019s okay as long as it remains consistent from day to day. If effectiveness or side effects are a problem, talk to your healthcare provider about adjusting the dose.\u00a0\u00a0<\/span><\/p>\n<h3 id=\"2-tell-your-healthcare-provider-about-all-medical-conditions-and-medications\"><span style=\"font-weight: 400;\">2.

Follow your healthcare provider\u2019s dietary recommendations<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">While taking spironolactone, your healthcare provider may tell you to limit salt intake. Salt substitutes that contain potassium should be limited as well, as they can raise your potassium levels too much. If you have low potassium, your provider may also recommend adding foods that are high in potassium, such as bananas, orange juice, and prunes.\u00a0<\/span><\/p>\n<h3 id=\"5-avoid-potassium-supplements\"><span style=\"font-weight: 400;\">5. Avoid potassium supplements<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Spironolactone may cause high potassium levels in the blood, a potentially dangerous condition. Many spironolactone side effects are due to high potassium, so it\u2019s a good idea to avoid dietary supplements that contain potassium when taking spironolactone.<\/span><\/p>\n<h3 id=\"6-do-not-substitute-tablets-and-oral-solution\"><span style=\"font-weight: 400;\">6.
