<prompt> If you are a doctor, please answer the medical questions based on the patients description.My 3 yr old daughter is on inhaled steroid for asthma. She had several white sores inside her mouth which I think may be thrush. I have nystatin cream USP, 100,000 per gram, From when she had a bad diaper rash. Is it okay to apply the cream inside her mouth.  <response>: Hi, thank you for posting. From what you refer I can say that your daughter suffer from Oral candidiasis thrush. To treat candidiasis I recommend Statin oral suspension 100 000 unitsml 30ml. The dosage is 2 ml, four times daily. Place one-half of dose, 1 ml, in each side of mouth and avoid feeding for 5 to 10 minutes. I dont recommend Statin cream that you have because it doesnt give effect anymore. It can give effect because it has more than 2 weeks opened.However, to be sure for the diagnosis you need:1. Oral culture.2. Complete blood count.3. Urine test. Contact a pediatrician. I hope this information is helpful. All the best.
