Ashlyna 91 Day is an extended-cycle combination hormonal oral contraceptive used to prevent pregnancy. It contains two hormones — Levonorgestrel (a synthetic progestin) and Ethinyl Estradiol (a synthetic estrogen). Unlike traditional 28-day birth control packs, Ashlyna uses a 91-day cycle, meaning you take active pills for 84 consecutive days followed by 7 days of low-dose estrogen pills. This extended-cycle design reduces the number of periods you have to approximately four per year. Ashlyna is manufactured by Glenmark Generics and is the generic equivalent of Seasonique.
Ashlyna is FDA-approved for prevention of pregnancy in females of reproductive potential. It is also used off-label for menstrual cycle regulation, reducing menstrual frequency, managing endometriosis-related symptoms, treating heavy menstrual bleeding, and managing menstrual migraines.
Ashlyna 91 Day works through three mechanisms to prevent pregnancy. First, it suppresses ovulation by inhibiting the release of gonadotropins (FSH and LH) from the pituitary gland, preventing the ovaries from releasing an egg. Second, it thickens cervical mucus, making it harder for sperm to reach the egg. Third, it alters the endometrial lining to reduce the likelihood of implantation. You take one tablet daily at the same time — 84 active tablets followed by 7 low-dose estrogen tablets — then start the next pack immediately without a break.
Ashlyna 91 Day scores a 60 out of 100 on our findability scale, meaning it can be moderately difficult to locate in stock. While it is not currently listed on the FDA drug shortage database, sporadic availability issues have been reported for extended-cycle oral contraceptives due to supply chain disruptions and manufacturer production schedules. Post-Dobbs demand shifts and manufacturing consolidation have contributed to intermittent availability for some generic oral contraceptive products since 2022. If your local pharmacy is out of stock, try calling nearby pharmacies or using Medfinder to locate it near you.
