There are 2 hormones in birth control pills:
- Estrogen – higher doses will increase the risk for blood clots but will also help with breakthrough bleeding or lower doses will also.
- Progesterone – causes 2 types of side effects Androgenic (acne), and progestin – higher progestin activity = less chance of bleeding.
Norgestimate does not have a higher dose estrogen and it’s known for breakthrough bleeding.
Zovia/Demulen has a 50mcg estrogen version and it has a higher progestin effect so will most likely stop the breakthrough bleeding
Medications such a Vyvanse and other ADHD meds rev up the liver and eat up the estrogen and other hormones in birth control so people on those meds sometimes need higher estrogen.
