Are there any other precautions or warnings for Aldactone?

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Breast enlargement in men: Men may develop breast enlargement with the use of spironolactone. If this occurs, tell your doctor. In the great majority of cases, breast enlargement disappears once the medication is stopped.

Drowsiness and dizziness: Spironolactone may cause drowsiness or dizziness. Do not drive or operate machinery until you know how this medication affects you. Alcohol can add to the drowsiness caused by this medication.

Potassium: This medication may cause high potassium levels if potassium intake is too high. Do not take potassium supplements, follow a diet rich in potassium, or use salt substitutes containing potassium while taking spironolactone. People with reduced kidney function, seniors, and people with diabetes are more at risk of developing high potassium levels.

Reduced liver function: People with reduced liver function should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Sodium: This medication can cause or worsen low sodium levels when given with diuretics (water pills). If you experience dry mouth, thirst, and drowsiness while taking this medication, contact your doctor.

Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.

Breast-feeding: This medication passes into breast milk. If you are a breast-feeding mother and are taking spironolactone, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.

  • change how you are taking one or both of the medications, or
  • leave everything as is.

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.

Medications other than those listed above may interact with this medication. Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.
