Errin
Errin (generic name: norethindrone) is a progestin-only birth control pill (also known as the "mini-pill") used to prevent pregnancy. It works by thickening the cervical mucus to prevent sperm from reaching an egg and altering the uterine lining to prevent implantation. Unlike combination birth control pills, Errin contains only progestin and is suitable for women who cannot tolerate estrogen.

Comprehensive Drug Guide
How Does Errin Work?
Errin prevents pregnancy primarily by thickening the cervical mucus, making it difficult for sperm to enter the uterus. It also changes the lining of the uterus to prevent a fertilized egg from implanting. In some cases, Errin may also suppress ovulation, but this is less consistent than with combination pills.
Common Dosages
- 0.35 mg norethindrone tablets, taken daily at the same time every day.
Typical Dosing
- Take one tablet daily at the same time each day, without any breaks between packs. It is essential to take Errin consistently to maintain its effectiveness.
Typical Dosing
FDA Approved Indications
- Prevention of pregnancy
Off-Label Uses
Who Shouldn't Take Errin?

- Undiagnosed vaginal bleeding

Advice From The Pharmacist
- Take Errin at the same time every day to maximize its effectiveness. Missing doses or taking them late increases the risk of pregnancy.
- Errin does not protect against sexually transmitted infections (STIs), so use condoms for additional protection if needed.
- If you miss a pill by more than 3 hours, use a backup method of contraception for at least 48 hours.
- Errin can be a good option for women who are breastfeeding or those who cannot use estrogen-containing birth control.
