NuvaRing is a combined contraceptive vaginal ring developed by Organon. One ring provides contraceptive protection for 1 cycle by inhibiting ovulation. The ring can be easily inserted and removed by the woman herself. After insertion, the ring should remain inserted for 3 weeks followed by a ring-free interval. The ring should always be used on the same day of the week: if it was inserted on a Wednesday, it should be removed 3 weeks later, again on a Wednesday. After the ring-free interval, a new ring should be inserted, again on a Wednesday. Once inserted, each ring releases 15 μ g EE and 120 μ g ENG per day.
The ring is made of the plastic EVA. (Ethylene Venyl Acetate) with an outer diameter of 54 mm and a cross-sectional diameter of 4 mm. It contains ethinylestradiol (EE) and etonogestrel (ENG) uniformly dispersed in the E.V.A. core, that is surrounded by a thin outer layer that is 100% E.V.A.
To insert NuvaRing, the woman should find a position that allows her to insert the ring easily (for instance, standing with one leg raised, squatting or lying down). The ring is then compressed between the thumb and index finger and inserted into a comfortable position in the vagina.
For insertion, NuvaRing is compressed and inserted into the vagina. The ring should sit comfortably in the vagina; if it feels uncomfortable, it might be necessary to gently push it in a little further. The exact position of NuvaRing in the vagina is not critical for efficacy. The ring does not need to be placed around the neck of the cervix. The circular shape and flexibility of the ring allows a good fit, minimizing the risk of expulsion. The ring is easily removed by hooking the index finger around the ring or by grasping the ring between the index finger and the middle finger and just pulling it out. The used ring should be placed in the ring sachet.
In addition to once-a-month administration, these additional aspect offer benefits to women using NuvaRing
