Is it normal for my yeast infection rx meds to make me itch MORE?

Every time I use the cream it makes me itch SO bad. I'm on day four of it and yesterday I didn't use it at all because I wasn't itching finally and just needed a break from it. Used it again tonight for the third time and I'm back to itching terribly. I can't take this! I have to wear a pad with it too or the cream just soaks my underwear. This is a prescription med. not the otc cream. I need it to go away!
