If sensitivity is due to the spermicidal agents, however, the method may have to be abandoned. An allergy to latex, although rare, may also necessitate discontinuation. Pelvic pain, cramps, urinary retention, bladder symptoms, or recurrent bladder infections may also occur with diaphragm use. Foul smelling, profuse vaginal discharge may occur if the diaphragm is forgotten or left in place too long. Removal for cleansing is recommended at least once every 24 hours.
Some women prefer to have two diaphragms to permit time for each to dry after use.
Risk of toxic shock could result if the diaphragm is left in place for prolonged periods of time.
