Were you looking for information about Amethyst? Amathist is a common misspelling of Amethyst.
Amethyst™ (levonorgestrel/ethinyl estradiol) is a combined oral contraceptive, meaning it contains a combination of two different hormones (an estrogen and a progestin). This prescription birth control pill works to prevent pregnancy by stopping ovulation, changing the cervical mucus, and altering the lining of the uterus. Common side effects include headaches, nausea, and breast tenderness.
