I had a lung tx 1/12 ago and was givenMycelex to prevent thrush in my mouth.  I stopped taking it at about one year...then developed thrush in mouth for first time, and re started it.  Now I have thrush again and my regular doctor is prescribing Nistatin.....question is....should I quit sucking on these Mycelex tabs while taking Nistatin?  Thank you for your answer.Im also in Stage 4 CKD            Sorry, I forgot that I would have to pay.                 Joy K
Welcome to the forum. Both the medicines are prescribed to take care of the thrush and hence can be taken together. Please post your exact question and let me know the form of the medicine, that is tablet/ cream and so on. Take care.
