Is there something i can take if i can't seem to use a vaginal suppository meant to cure a yeast infection?

What does "can't use" a suppository mean? If difficulty inserting it, try one of the many vaginal creams instead of suppository. There also is effective oral treatment, a single dose of fluconazole by mouth. Any product with active ingredient ending in "azole" is likely to be equally effective -- assuming the diagnosis of yeast infection is certain. If not, see a doctor or clinic. Good luck.
