Drugs Home > What Is Errin Used For?

Errin is used for preventing pregnancy in women of reproductive age. It is a progestin-only oral contraceptive that is most commonly used by breastfeeding women and women who cannot take estrogens for other reasons. Healthcare providers may occasionally recommend off-label Errin uses, such as for treating heavy menstrual bleeding and painful menstrual periods.

An Overview of Errin Uses

Errin® (norethindrone) is an oral contraceptive, more commonly known as a birth control pill. It is a generic version of Ortho Micronor®. Errin is a progestin-only contraceptive, which means that it contains only a progesterone-like hormone, not an estrogen (most birth control pills contain both types of hormones). It is most often used by women who are breastfeeding or cannot take estrogens for other reasons.
As with almost all methods of birth control, Errin must be used correctly and consistently. In fact, being just a few hours late taking a pill increases your risk of pregnancy. More importantly, Errin does not protect against HIV or other sexually transmitted diseases (STDs). In many situations, it is advisable to use condoms in addition to Errin (to prevent transmission of STDs).
Today, women can choose from a large variety of different birth control options. Each method has its own advantages and disadvantages, and no particular birth control method is right for all women. Some of the most commonly used birth control methods include:
  • Barrier contraceptives -- Condoms, diaphragms, cervical caps, and various other methods that physically block the sperm from entering the uterus
  • Spermicides -- Foams, jellies, gels, suppositories, and inserts
  • Periodic abstinence, sometimes known as natural family planning or the rhythm method -- Avoiding intercourse during the fertile phase of your menstrual cycle
  • Withdrawal -- Removing the penis from the vagina prior to ejaculation
  • Combined hormonal contraceptives (which contain a progestin and an estrogen) -- Most birth control pills, patches, and rings
  • Progestin-only contraceptives -- Some birth control pills ("mini-pills"), injections, and implants
  • Intrauterine devices (IUDs) -- Implanted devices that are both very effective and reversible
  • Surgical sterilization -- Tubal ligation (getting your "tubes tied") or vasectomy (for men).
Unlike most birth control pills, Errin falls into the category of progestin-only contraceptives, as it contains just a progestin (without any estrogen).
