I just recently went to the doctor and was given 4 prescriptions. cipro 500mg, prednisone 5mg, phenergan dm, and astepro .15%. Now I have a severe itch and pain in my vaginal area that I cant get rid of. I refuse to take anymore of my medicine even though I need it, in fear that this will get worse. My 1st guess is a yeast infection . But can it be an allergic reaction?
