Vaginalspermicidesarefemalebarriercontraceptiveswhichcoatthecervixandinactivatespermby dissolvingthelipidcomponentsintheircellwalls.Manydifferentvaginalspermicidalagentsare available,includingfoams,jellies,creams,suppositories,spongesandfilms. In theUS,all spermicides useNonoxynol-9(N-9)astheiractiveingredient.Thetypicalusefirst yearfailureratewithspermicides isquotedtobeabout28%butrecentstudiessuggestthatthefirstyeartypicalusefailureratemaybeas highas40%.Thefailureratewithcorrectandconsistentuseis18%.Spermicideswithlower concentrationsofN-9havehigherfailurerates. Spermicidesareoftenusedinconjunctionwithother barriermethods,suchasdiaphragms,cervicalcapsandmalecondoms. Spermicidesdonotreducethe riskofSTIs and transmission of the Zika virus.In fact,multipleusesdailyofnonoxynol-9spermicidesmayincreasetheriskofHIV infectionacquisitionortransmissioninat-riskwomen.Newercompoundsarebeingtestedforuseas spermicides.

- Advise sponge users that vaginal dryness may develop with sponge use. Other forms of spermicide may cause an increase in vaginal secretions.
- Remind patient that spermicides do not protect against sexually transmitted infections, including HIV/AIDS and Zika.
- Zika virus education and prevention strategies
- Avoid traveling to impacted areas
- Avoiding mosquito bites if traveling to impacted areas
- Using condoms to prevent transmission of virus
- Avoiding pregnancy if infected or partner infected
