Nystrin is an oral suspension containing Nystatin, with a concentration of 100,000 units per milliliter. It is an antifungal medication used to treat fungal infections in the mouth, throat, and intestines, such as candidiasis (thrush). Nystrin works by inhibiting the growth of the fungi, thereby clearing up the infection. This 30ml bottle of oral drops is typically used for infants, children, or adults who require treatment for localized fungal infections. The drops are administered as prescribed by a healthcare professional, and it is important to complete the full course of treatment to ensure the infection is fully resolved.
