Treatments Your Provider May Prescribe
Although meticulous oral hygiene practices must be followed, treatments center on killing the overgrown yeast with anti-fungal medications.
  • Nystatin – This medicine must come into contact with the yeast in order to kill it. Nystatin comes in a liquid (suspension) and in a lozenge (troche). The suspension is swished around the mouth and then swallowed. The lozenge dissolves in the mouth. Both the suspension and the lozenge are used several times a day until the lesions are completely gone.
  • Amphotericin B suspension – The suspension is swished and swallowed several times a day until complete resolution of the lesions.
  • Clotrimazole lozenge – The lozenge is dissolved in the mouth several times a day until the lesions have disappeared entirely.
  • Fluconazole pill – This medication is swallowed once daily for 5–10 days.
