What is nonoxynol-9 vaginal, and what is it used for?
Nonoxynol-9 is available over the counter (OTC) in several forms such as gels, foams, inserts, films, and sponges that are applied or placed in the vagina. Nonoxynol-9 works as a locally acting spermicide during intercourse and kills the sperm in the vagina, without producing any systemic effects.
Nonoxynol-9 is a chemical compound that reduces surface tension (surfactant). Nonoxynol-9 acts on the surface of the sperm and damages its cell membrane, thereby immobilizing, inactivating and killing the sperm. Most nonoxynol-9 products are required to be used before each act of intercourse and remain effective locally, usually for an hour. Some of the nonoxynol-9 products such as the vaginal sponge also work as barrier contraceptives.
Nonoxynol-9 has a higher failure rate than other contraception methods, and does not provide protection against human immunodeficiency virus (HIV) or other sexually transmitted diseases. Nonoxynol-9 should ideally be used along with vaginal diaphragms or male latex condoms for more effective contraception. Proper use of condoms reduces the risk of HIV transmission, although, it does not completely eliminate the risk.
- Do not use nonoxynol-9 products if you are hypersensitive to any of the components in the products.
- Do not use vaginal sponge:
- If you are allergic to sulfites; vaginal sponge contains metabisulfate
- During menstrual periods
- Within 6 weeks after giving birth
- Do not use nonoxynol-9 if your partner has or you have HIV/AIDS. Nonoxynol-9 may cause vaginal irritation, or may adversely affect lactobacillus, disrupting the vaginal lining and causing ulceration, both of which can increase the risk of HIV transmission.
- Do not use nonoxynol-9 if you have chronic or recurrent bacterial vaginosis.
- Do not use vaginal sponge without consulting your healthcare provider if you have had a recent miscarriage or abortion.
- Do not use vaginal sponge if you have conditions such as vaginal septum or uterine prolapse which may affect its efficacy.
- There have been rare and sometimes fatal reports of toxic shock syndrome (TSS), with the use of barrier contraceptives, including vaginal sponge. If you experience symptoms such as fever, nausea, vomiting, diarrhea, muscle pain, dizziness, faintness, or a sunburn-like rash on face or body, remove the sponge and seek medical help immediately.
- Nonxynol-9 is for vaginal use only. Rectal use can cause irritation and increase the risk for HIV transmission.

Increased risk factors for DVT and birth control pills include over 40 years of age, family history, smoking, and obesity. Other medical problems that increase the risks of blood clots, for example, lung or heart disease, or inflammatory bowel disease or IBD (Crohn's disease and ulcerative colitis (UC).
