What is it?

The vaginal ring is a flexible ring that releases two hormones (estrogen and progestin) that are absorbed by the vagina.  The ring is inserted into the vagina where it stays for a total of three weeks.  The ring is then removed and the woman has one “ring free” week.

How does it work?

Like the birth control pill, the ring prevents pregnancy by:

• preventing the ovaries from releasing an egg;
• making the cervical mucous thicker;
• making the lining of the uterus thin so the egg can’t stick.

 

Advantages

• about 99% effective if used perfectly
• once a month
• makes periods more regular;
• does not interfere with intercourse;
• probably similar benefits to the pill but no research available yet.

Disadvantages:

• you need to go to a doctor or clinic to get the ring;
• may not be covered by all drug plans and can cost up to $35 per month at a pharmacy;
• possible side effects include irregular bleeding or spotting, nausea, breast tenderness, and headache.  Serious side effects like blood clots are rare;
• may cause vaginal discomfort or irritation (but uncommon);
• the ring may fall out, but this is rare.

 

Remember:

• the ring does not protect against sexually transmitted infections.  Use condoms every time; and
• if you smoke – quit.  Smoking while on the ring increases the risk of serious side effects on the heart and blood vessels.
