The FDA has approved a new once-weekly birth control patch that delivers less estrogen than the patch already on the market, and the approval comes with a restriction that will determine eligibility for a large share of American women.
Gwyn Lo, from Viatris, is a combined hormonal contraceptive patch approved on July 29 for the prevention of pregnancy in women with a body mass index below 30 kg/m2. It is contraindicated in women with a BMI of 30 or above.
