People taking the medication spironolactone for acne have been advised to avoid certain foods due to potential side effects. The drug, commonly prescribed for heart problems, high blood pressure, and fluid retention, is also used 'off licence' to treat acne in women, according to the British Association of Dermatologists.
The NHS confirms that spironolactone is a safe and effective alternative to antibiotics for women with acne, but warns that patients should not consume low-sodium salt substitutes like Lo-Salt, as they contain high levels of potassium that can interact with the medication. Additionally, foods rich in potassium, such as bananas, avocados, pulses, nuts, and salmon, should be limited to prevent excessively high potassium levels.
Spironolactone does not cure acne but can help manage and clear it over time. Most women notice improvement after three months, with full benefits seen after six months of treatment. The typical dosage ranges from 50mg to 150mg daily, starting at 50mg per day for one month, with potential increases based on tolerance and blood test results.
The NHS advises taking spironolactone tablets whole with water after a meal and informs patients to consult their doctor about any other medications they are taking before starting treatment. For more details, visit the NHS website or speak to your GP.
