Amethyst, a generic version of Lybrel, is a medication used to prevent pregnancy. Unlike most other birth control pills, this product does not contain any inactive tablets; this allows women to take the product without having a regular monthly period. Unpredictable bleeding or spotting, however, may occur as a side effect, as can headaches, nausea, and breast tenderness.

What Is Amethyst?

Amethyst™ (levonorgestrel/ethinyl estradiol) is an oral contraceptive (birth control pill). It is approved to be taken continuously, with no inactive pills at all. While taking Amethyst, women will not have regular monthly periods, although they will probably experience some unpredictable bleeding and spotting from time to time.
Amethyst is a generic version of Lybrel®.

Are There Side Effects?

As with any medicine, side effects are possible with Amethyst. However, not everyone who uses the contraceptive will experience problems. In fact, most people tolerate it quite well.
If side effects do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider. Serious reactions are less common.
Common side effects of Amethyst include but are not limited to:
  • Bleeding or spotting (even though you will not have a regular, monthly period)
  • Nausea
  • Vomiting
  • Breast tenderness
  • Headaches.
