STD Home > Alyacen

As a type of birth control pill, Alyacen helps to prevent pregnancy by stopping ovulation, altering the uterine lining, and changing the cervical mucus. The medicine comes in two different forms, which are actually generic versions of Ortho-Novum 1/35 and Ortho-Novum 7/7/7. It is important to take one pill a day, at the same time each day. Possible side effects include nausea, acne, and headaches.

What Is Alyacen?

Alyacen™ (norethindrone and ethinyl estradiol) is a prescription birth control pill. Two different types of Alyacen birth control pills are available:
  • Alyacen 7/7/7, a triphasic birth control pill (generic for Ortho-Novum® 7/7/7)
  • Alyacen 1/35, a monophasic birth control pill (generic for Ortho-Novum 1/35).
(Click What Is Alyacen Used For? for more information on this topic, including possible off-label uses.)

Are There Side Effects?

Just like any medicine, Alyacen may cause side effects. However, not everyone who takes the contraceptive will experience problems. In fact, most women tolerate it quite well.
If reactions do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider. Serious side effects are less common.
Common side effects of Alyacen include but are not limited to:
  • Nausea (with or without vomiting)
  • Breast tenderness
  • Breakthrough bleeding or spotting between periods
  • Acne
  • Headaches.
