Does Errin contain estrogen?

Errin is a brand name for progestin-only contraception (a progestin pill). With progestin-only pills, the product is designed not to contain estrogen—so Errin does not have estrogen.

What kind of hormone does Errin have instead?

Errin uses a progestin to help prevent pregnancy (it changes cervical mucus and affects the uterine lining). Because it is progestin-only, it avoids the estrogen component found in many combined oral contraceptives.

Are there any exceptions (different countries or formulations)?

If you mean a different “Errin” product (for example, another country’s brand naming) or a different formulation, the hormone content can differ. To be sure, check the package for the active ingredient (the exact progestin name and strength).

If you tell me the active ingredient written on your Errin package (or share the label text), I can confirm whether it includes estrogen.
