Common Questions about Spironolactone


Are Aldactone and CaroSpir the same?

Brand name drugs Aldactone and CaroSpri both contain spironolactone as the active ingredient. However, they are not the same. Do not interchange the two forms for each other without talking to your healthcare provider. Aldactone is in tablet form and a lower-cost generic is available. CaroSpir is a liquid suspension and it is brand name only. Also, spironolactone tablets are approved to treat two additional conditions, edema due to nephrotic syndrome and primary aldosteronism. 



Can spironolactone help you lose weight?

Spironolactone is not a weight loss drug. However, it is a diuretic that helps the kidneys remove excess fluid and salt from the body. The removal of excess fluid can result in weight loss. This type of medication-induced water weight loss is not the same as healthy weight loss achieved with diet and exercise.



What foods should be avoided when taking spironolactone?

You may need to limit but not completely avoid certain potassium-rich foods, such as bananas, avocados, and prunes, while on spironolactone. Talk to your provider about which foods you can and cannot eat. Do not take potassium supplements or salt substitutes without talking to your doctor. 



Should I take spironolactone in the morning or at night?

Spironolactone is usually prescribed to be taken once a day in the morning. If you are on high-dose spironolactone, your doctor may ask you to take it in two divided doses, morning and evening. Take your evening dose several hours before bedtime to avoid getting up in the middle of the night to urinate. 



Is spironolactone safe to take while pregnant?

Spironolactone is not safe to take while pregnant. This medicine has anti-androgenic effects and can cause feminization of a male fetus. Tell your doctor if you are pregnant before starting spironolactone. Call your doctor without delay if you become pregnant while on this medicine.
