Can medication cause thrush

Good question, but not usually. The common medicines that can cause yeast infections are antibiotics.

Your vagina has a very tempermental pH balance of good bacteria and yeast. Both are there all the time, the yeast grows and the good bacteria eats it. They naturally maintain a healthy level of each.

However, when you take antibiotics, this medicine kills off any kind of bacteria, even the good kind living in your vagina. Now, this is good because it will kill the infection for which it was prescribed, but will also kill off good bacteria- leaving nothing to balance out the yeast. The yeast builds up and causes a yeast infection.

Pain killers shouldn't disrupt the balance of yeast and good bacteria so you should be safe. Here is a link to help you better understand yeast infections and medicinal interactions... https://www.msu.edu/~eisthen/yeast/causes.html

Good luck! :)
