Product details

Jencycla is a once-a-day oral contraceptive that works by thickening the cervical mucus at the entrance to the uterus in order to keep sperm from passing through.

Because Jencycla is a progestin-only pill, it should not interfere with breastfeeding or affect milk production. Our team at Nurx can prescribe Jencycla at special request, or can offer the generic equivalent Errin for as low as $0 with insurance or as little as $15 without insurance.
