I took penicillin and i got a yeast infection?

Antibiotics n' yeast: Antibiotics kill bacteria. Some bacteria in certain body areas are normal and good. If they are killed off, it can allow other things to grow instead--yeast. Some women are very susceptible and antibiotics will often produce a yeast infection. If this is you, asking for a Fluconazole pill along with your antibiotic prescription may be an answer.
