What is Errin?
Errin is a progestin-only contraceptive pill. It’s typically used for preventing pregnancy, but doctors can also prescribe it to treat conditions like endometriosis, and the symptoms of pain and heavy, irregular, bleeding.
Contraceptive pills are the first-line of treatment for endometriosis. Progestins like Errin are considered one of the best long-term treatments as they don’t contain estrogen, so there’s lowered health risks.[1]
How does Errin work for endometriosis?
Errin works by lowering the estrogen in your body and reducing the growth of endometriosis lesions.[1] This then helps to reduce inflammation and pain.
It also reduces the production of prostaglandins, which are hormone-like chemicals linked with pain and inflammation in endometriosis.[1] Some studies show that this can lower the chance of flare-ups and lead to lighter or stopped periods.[2]
Will I get side effects using Errin?
You might. Like all hormonal treatments, Errin can cause irregular bleeding, headaches, breast tenderness, acne, or mood changes. Some people also notice nausea or changes in their sex drive.
But unlike estrogen-containing pills, Errin doesn’t increase the risk of blood clots. So it’s often a safer choice if you’re over 35 or have other risk factors.[3]
What doses of Errin are there?
There’s just one dose of Errin, which contains 0.35mg of norethindrone. You’ll use each pack back to pack, taking one pill at the same time every day.
