Eloira intrauterine device is a small, soft, flexible plastic system that is placed in the uterus to prevent pregnancy. It can be used for up to five years.

Eloira intrauterine system releases a small amount of levonorgestrel directly into the uterus. The amount of hormone present in the blood is much lower than that following the ingestion of oral contraceptive pills.

Eloira acts as a contraceptive by:

1. Creating a barrier preventing sperm from entering the uterus
2. Inhibiting movement and function of the sperm
3. Thinning the lining of the uterus

Occasionally, the release of eggs may be inhibited during the early stages of use of Eloira. Because of the thinner lining of the uterus, there is less monthly bleeding. Eloira prevents fertilization (the fusion of sperm with an egg). It does not cause abortion.

The diagram below shows the chance of getting pregnant for women who use different methods of birth control. The most effective methods, including IUS, are found at the top of the chart.
