Contraceptive vaginal system for use up to 1 year launches in Canada

On April 7, 2026, Canadian pharmaceutical company Duchesnay launched the Ringza contraceptive system in Canada, a system that is designed to be reused for up to 1 year, according to a press release from the company.

The vaginal ring is designed as a slow-release ring made of silicone for use for up to 13 menstrual cycles of weeks in, 1 week out, and is patient-controlled and reversible, which does not require insertion or removal by a clinician. The system delivers the first Canadian use of segesterone acetate in the country. The silicone design releases a daily dose of 0.15 mg segesterone acetate and 0.013 mg ethinyl estradiol.

"Canadian women are seeking contraceptive options that reflect their diverse lifestyles and empower them to make informed choices on their own terms,” said Diane Francoeur, MD, FRCSC, MHCM, ICD.D, CEO of SOGC, in a statement. “Any new contraceptive method is always welcome. This new contraceptive vaginal ring brings a new definition of autonomy with its convenience of only 1 ring per year supporting women's personal choice."

Duchesnay noted that the system is indicated for use by women of reproductive potential to prevent pregnancy and that it has not been “adequately studied in women with a body mass index of more than 29 kg/m².

Efficacy and safety were the subjects of a pair of clinical trials of 13-cycle duration. Headache, nausea, and vaginal discharge were the most common adverse reactions (≥10%) observed in the trials.

“Ringza is an important new contraceptive option that provides bleeding patterns consistent with a planned withdrawal bleed, a priority for many women," said Cleve Ziegler, MD, FRCSC, Director of Gynecology at the Jewish General Hospital, a McGill University-affiliated teaching hospital, in a press release. "With minimal monthly management and a single pharmacy visit per year, it likely supports women's adherence to their contraceptive choice. Women being in control of their contraception allows them to focus on their daily activities."
