Smart Shopping for Contraceptive Sponges

The contraceptive sponge is a hormone-free barrier form of birth control that prevents sperm from entering the uterus by physically blocking the cervix as well as using spermicide to avoid conception. Made of polyurethane and shaped like a dome, the contraceptive sponge is made to feel like vaginal tissue so there is little to no interference during intercourse. A contraceptive sponge can be left inside the vagina for up to 24 hours, although after intercourse the sponge must stay in place for 6 hours. There is also no need to use additional spermicide.

In 1994, the contraceptive sponge was pulled from shelves in the United States. A lot of speculation arose as to the safety of the sponge. In reality, the safety of the contraceptive sponge was never a concern. The FDA had mandated changes to the equipment that produced the sponge and the manufacturers chose not to do so, halting production. In 2005, the contraceptive sponge made its way back onto shelves in the United States with FDA approval.

What to Look for

Unlike other birth control methods, the contraceptive sponge is sold over-the-counter, without a prescription and no special fittings are needed. They are relatively inexpensive and can be bought online and in pharmacies and drugstores.

As with any health products, be sure to check any expiration dates. The contraceptive sponge should still be in its original packaging, with no evidence of tampering.

Common Pitfalls

Typical rates of effectiveness hover from 84 to 91 percent if used correctly and consistently. If a woman has given birth, the rates drop around 68 to 74 percent, again if used correctly and consistently. These percentages are not as high as the contraceptive pill and may cause concern for some women. Using a condom along with a contraceptive sponge will improve effectiveness in preventing pregnancy.

A contraceptive sponge can help prevent pregnancy, but it can not protect you from sexually transmitted diseases (STDs). Do not use a sponge if you are at risk or are unsure of your risk.

If you have certain allergies, are having your menstrual period, have given birth within the last 6 weeks or have suffered from toxic shock syndrome (TSS), you should not use a contraceptive sponge as birth control.

Toxic Shock Syndrome is a rare bacterial infection that occurs in women who use high absorbency tampons during their menstrual period. Women who use a contraceptive sponge for birth control purposes are at a slightly increased risk when using barrier contraceptives. Symptoms of TSS include: sudden fever, rash, vomiting and diarrhea, sore throat, aching muscles and joints, dizziness, faintness or weakness. If you experience any of these symptoms in relation to your use of a contraceptive sponge contact your health care provider immediately.
