Hang in there, I had both together and the burn was horrible... finished antibiotics and used the cream, together actually because of the burn. Doc said to just keep using the cream.
Use the cream, finish antibiotics, take probiotics, tablet form even while you're on antibiotics (antibiotics target the bad bacteria but kill the good in the process. Sending in good bacteria (in probiotic tablets) whilst you're on antibiotics means you still have some form of gut protection). After antibiotics, take an SB probiotic to recolonize your gut with good bacteria (this will impact your good bacteria levels in vagina too).
I had that too due to antibiotics. My doctor said to me its best to finish of the antibiotics for the treatment of uti first and only AFTER that treat the yeast infection cuz it wouldnt go away othrwise. Bt u cud still use the cream for the itch while ur on the antibiotic. I did as the doctor said and i was given a 3 day treatment for the yeast infection. But it wudnt go away just got worse so I went back to doctor and she gave me a weeks supply of the treatment and finally im now yeast free!! Lol
