While spironolactone?one of the active ingredients in Fruselac?is sometimes used to treat facial hair, Fruselac also contains frusemide, a strong fluid-clearing medication. Taking this combination pill solely for hair growth is not recommended, as frusemide can cause unnecessary dehydration and chemical imbalances when you do not have swelling. It is much safer to speak with your doctor about using spironolactone alone, or exploring other targeted treatments specifically approved for PCOS symptoms.
