It's just the same fungus as the one that infects your lady bits so yes you can (ask the pharmacist to be sure), it's what Kaya gets for her thrush nappy rash. I had thrush in the breasts and nipples and it cleared up just with the cream. The cream I used was Clotrimazole but again the doc said it could be used on Kaya for her nappy rash. I believe that yogurt and garlic are also good for it, but you'd have to look that up.
