Overview Of Spironolactone

Potential Side Effects

Patients taking spironolactone could experience side effects that range from mild to severe. Some of the most frequently reported side effects of this medication include stomach irritation and elevated potassium. Less commonly, spironolactone could cause headaches, dizziness, and low levels of magnesium or sodium in the blood. Some patients have noticed breast enlargement while taking this medicine, and the drug may affect sexual function. While using this medicine, patients should let their doctor know immediately if they develop chest pain, bloody stools, clay-colored stools, bleeding gums, or constipation. They should also seek prompt medical care if they notice swallowing difficulties, cloudy urine, blurred vision, dimpling of the breast skin, or nipple discharge while taking spironolactone. In rare cases, this medicine can cause a potentially life-threatening condition known as Stevens-Johnson syndrome. This condition causes the skin to blister and peel, and blisters also form inside the body. Patients who use spironolactone should monitor their skin and report any skin pain, rashes, welts, sores, or blisters to their doctor immediately.
