No effect: Diflucan (fluconazole) is particularly good at killing yeast infection--with a single dose. It poses no risk to the fetus.

I agree with Dr. Fowler--multiple dose Diflucan may reduce effectiveness of birth control pills and a backup birth control method is recommended. A single dose will not interfere the the bop's efficacy.

Diflucan: Per Drugs.Com -Oral contraceptive pills (OCP) & other hormone-based birth control may be less effective when Diflucan (fluconazole) is used wi recommendation for use of backup birth control. BUT Pfizer Medical Information. Com – indicates that there was no effect on OCP at 50mg of Diflucan & there were higher levels of ethinyl estradiol & levonorgestrel with higher doses of Diflucan. Single dose
