For Oral Thrush "I was on antibiotics for an extended time and after 4 months, I developed thrush. After starting this medicine, I noticed my mouth became extremely dry, especially at night while sleeping. My tongue had a funny burning sensation and everything tasted odd. Has anyone else had this same problem? Also, I got really bad diarrhea and stomach cramps."

For Oral Thrush "It took 7 full days, 5 ml, for my oral thrush infection to clear. The usual time is 2-3 days, but since I'm immunocompromised, it took me longer to heal. I had only a stomach ache for 2 out of the 7 days while on this medication. No other symptoms!"

For Oral Thrush "I took it as a swish and spit for thrush. After a few days, I developed dry mouth and a bit of burning after I took it. Some stomach cramps also occurred. None of these side-effect symptoms were too much, and I finished a 2-week prescription."

For Oral Thrush "I developed oral thrush after being on antibiotics and methylprednisolone for oral surgery. I was prescribed nystatin rinse and was told to rinse and spit and not swallow, which I followed. It almost immediately made me dizzy and lightheaded. My stomach was upset and gurgling. After the second time taking it, I had diarrhea three times. My surgeon couldn’t understand how I could get diarrhea and GI upset if I wasn’t swallowing… but I was. It was clear when my stool was orangey-yellow like nystatin. I was then advised to stop and try fluconazole. Currently taking that with no issues (only taken it twice) and improvement but still working on it."
