SyreniRing (etonogestrel/ethinyl estradiol) Vaginal Contraceptive Ring

SyreniRing is a contraceptive vaginal ring used to prevent pregnancy. Each ring contains a small amount of two female sex hormones – etonogestrel and ethinylestradiol. The ring slowly releases these hormones into the blood circulation. Because of the low amount of hormones that is released, SyreniRing is considered a low-dose hormonal contraceptive. Since SyreniRing releases two different types of hormones it is a so-called combined hormonal contraceptive.

SyreniRing works just like a combined contraceptive pill (the Pill) but instead of taking a pill every day, the ring is used for 3 weeks in a row.

SyreniRing releases two female sex hormones that prevent the release of an egg cell from the ovaries. If no egg cell is released you cannot become pregnant.




Therapeutic indications


SyreniRing is intended for women of fertile age. The safety and efficacy have been established in women aged 18 to 40 years.

The decision to prescribe SyreniRing should take into consideration the individual woman’s current risk factors, particularly those for venous thromboembolism (VTE), and how the risk of VTE with SyreniRing compares with other combined hormonal contraceptives (CHCs)
