How the Diaphragm is Used
Your health care provider will give you a physical exam and fitting to determine the correct size of diaphragm. The diaphragm is used with spermicidal cream or jelly and is inserted into the vagina up to six hours before intercourse and may be left in place for 24 hours. After intercourse, the diaphragm must be left in place for at least six hours. If sexual intercourse is repeated during these six hours, more jelly must be inserted into the vagina without removing the diaphragm.
You need to receive a complete gynecological exam every year. It is recommended that your diaphragm fitting is checked also, especially if you have had a change in weight or a recent pregnancy. If you have any of the following problems, contact your health care provider:
Any discomfort when diaphragm is in place
If diaphragm does not stay in place
Irritation or itching
Frequent bladder infections
Unusual vaginal discharge
