    Precautions and Warnings

    Spermicidal contraceptives are useful additional safeguards when used in conjunction with barrier methods of contraception such as condoms, diaphragms and caps, but are not a totally reliable form of contraception.

    The preparation should be applied or re-applied not more than 3 hours before intercourse and between repeated acts of sexual intercourse (see adult dosage).
    The diaphragm /cap must be left in place for 6 - 8 hours post coitus, but not for longer than 24 hours (see adult dosage).
    Advise patient to avoid douching for at least 6 hours after intercourse.

    Intravaginal spermicidal contraceptive preparations do not protect against HIV or other sexually transmitted diseases. Frequent use may cause epithelial damage and increase the risk of HIV infection. Women at risk of HIV or other sexually transmitted diseases or who have multiple daily acts of intercourse should be advised to use a different form of contraception.

    Advise patient that if vaginal or penile irritation occurs, they should discontinue use and if symptoms worsen or continue for more than 48 hours, they should seek medical advice.

    CSM Warnings

    Products such as petroleum jelly, baby-oil and oil based vaginal and rectal preparations are likely to damage condoms and contraceptive diaphragms made from latex rubber, and may render them less effective as a barrier method of contraception and as a protection from sexually transmitted diseases (including HIV).

    Pregnancy and Lactation

    Pregnancy

    Contraindicated during pregnancy.

    There is no evidence of nonoxinol - 9 being teratogenic. Human epidemiological studies have shown no evidence of foetotoxicity. However some animal studies have shown evidence of embryotoxicity.

    Lactation

    Contraindicated in lactation.

    Human studies have not been carried out in lactating women and animal studies have detected nonoxinol-9 milk after intravaginal administration.

    Effects on Ability to Drive and Operate Machinery

    Not known.

    Counselling

    Advise patient to discontinue use if vaginal or penile irritation occurs and to seek medical attention if these symptoms deteriorate or persist for more than 48 hours.

    Advise patient that spermicidal contraceptives are useful additional safeguards when used in conjunction with barrier methods of contraception such as condoms, diaphragms and caps, but are not a totally reliable form of contraception.

    Advise patient that intravaginal spermicidal contraceptive preparations do not protect against HIV or other sexually transmitted diseases and frequent use may cause epithelial damage and increase the risk of HIV infection. Therefore women at risk of HIV or other sexually transmitted diseases or who have multiple daily acts of intercourse should be advised to use a different form of contraception.
