Vaginal rings (also known as intravaginal rings, or V-Rings) are 'doughnut-shaped' polymeric drug delivery devices designed to provide controlled release of drugs to the vagina over extended periods of time. Several vaginal ring products are currently available, including:
Estring - a low-dose estradiol-releasing ring for the treatment of vaginal atrophy.
Femring - a low-dose estradiol-acetate releasing ring for the relief of hot flashes and vaginal atrophy associated with the menopause.
Nuvaring - a low-dose contraceptive vaginal ring releasing a progestogen [etonogestrel] and an estrogen.

Method of use
The Nuvaring is inserted into the vagina and left in place for three weeks, after which it is removed for a 'ring-free' week to allow menstruation to occur. The ring is held in place by the vaginal walls during the three week period. Nuvaring can remain in place during intercourse. If a couple prefers it can be removed for intercourse, but only for very finite periods of time (an hour, around three hours max to maintain efficacy of birth control properties). Most couples do not report interference or discomfort by leaving Nuvaring in place during intercourse. It is often not even felt.

Warnings and review
In rare cases Nuvaring can be expelled from the body without the woman's knowledge; often as a result of constipation. If you think this may be the case it is good to check, but it is rare.
The NuvaRing prescription is similar to birth control pills, requiring an annual pap and physical. |
