Thanks for writing in.
I think it would be better if your treating doctor took a look at it and decided. If you are not responding to nystatin
, the doctor might prescribe oral antifungals like fluconazole
Other measures you could try are warm saline gargles (swish and spit) .
It might help if you up your intake of curd which has the good bacteria (lactobacilli) which might help restore the normal bacterial flora.
Hope this helps.
Wish you a speedy recovery.
Dr. Divya Kuttikrishnan.
