Hi Judy Yes, you're right, nystatin is for candida, and is quite 'narrow spectrum' whereas clotrimazole and most other antifungals are broad spectrum and are active against a host of different fungal agents. I have found that treating candida with nystatin is sometimes frustrating as it doesn't seem to work - not just on candidia of the breast, but also nappy and vaginal candidia. I know a lot of my local gynaecologists are not suggesting nystatin anymore as a firstline treatment for vaginal thrush as it seems to take longer to work and have more failures than using a broad spectrum one. What have other people experienced?
