The significant risk associated with prolonged use of a contraceptive sponge is toxic shock syndrome. This condition is a rare but serious bacterial infection that can occur when a sponge is left in the vagina for too long, creating an environment that facilitates bacterial growth. The sponge can retain blood and other fluids, which are nutrient sources for bacteria, leading to an increased risk of developing toxins that can cause severe illness.

Many health advisory organizations recommend that the sponge be removed after a designated period to minimize the risk of toxic shock syndrome. Symptoms may include high fever, rash, and changes in mental status, which necessitate prompt medical attention.

While unplanned pregnancy, vaginal dryness, and allergic reactions to rubber can occur with contraceptive sponge use, they are not considered significant risks directly linked to prolonged use as is the case with toxic shock syndrome. Unplanned pregnancy can occur if the sponge is not used correctly or if it is not effective, but it is not an inherent risk of prolonged use. Similarly, vaginal dryness may happen but is not directly related to the length of time the sponge is in place, and allergic reactions, while possible, are less commonly associated with the contraceptive sponge than toxic shock syndrome.
