The side effects of cyproterone acetate (CPA), a steroidal antiandrogen and progestin, including its frequent and rare side effects, have been studied and characterized.It is generally well-tolerated and has a mild side-effect profile, regardless of dosage, when it used as a progestin or antiandrogen in combination with an estrogen such as ethinylestradiol or estradiol valerate in women.
The placebo, or hormone-free, week in the 28-day pill package simulates an average menstrual cycle, though the hormonal events during a pill cycle are significantly different from those of a normal ovulatory menstrual cycle. Because the pill suppresses ovulation (to be discussed more in the Mechanism of action section), birth control users do ...
Oral contraceptives, abbreviated OCPs, also known as birth control pills, are medications taken by mouth for the purpose of birth control.

[1] Calcium is particularly important for bones, muscles, and nerves. [1]
[49] [2] A review indicated the usefulness of using calcium channel blockers. [32] Heat is effective compared to NSAIDs and is a preferred option by many patients, as it is easy to access and has no known side effects. [50] Tamoxifen has been used effectively to reduce uterine contractility and pain in dysmenorrhea patients. [51]
Side effects of NOMAC include menstrual irregularities, headaches, nausea, breast tenderness, and others. [1] [14] NOMAC is a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone. [3] It has some antiandrogenic activity and no other important ...
