I have lupus/fibro and on of the things that happens alot is I get thrush very frequently. The other day my husband had bought me a mountain dew which I only took a few swigs of. My son found it and thought it was for him and he drank it. Now he has my thrush on top of the cold he already had. I feel so bad. My nystatin swish and swallow is almost gone but my thrush is not and his is even worse guess I will be calling doc for refill. BTW does anyone know can I send him to school with thrush?
