Progesterone is well tolerated and often produces few or no side effects. [28] However, a number of side effects are possible, for instance mood changes. [28] If progesterone is taken by mouth or at high doses, certain central side effects including sedation, sleepiness, and cognitive impairment can also occur.
[10] Common side effects include menstrual disturbances such as absence of periods, abdominal pain, and headaches. [10] More serious side effects include bone loss, blood clots, allergic reactions, and liver problems. [10] Use is not recommended during pregnancy as it may harm the baby. [10]
[1] [47] At high doses, due to their antigonadotropic effects, progestogens can cause low sex hormone levels and associated side effects like diminished secondary sexual characteristics, sexual dysfunction (e.g., reduced sex drive and erectile dysfunction), reversible infertility, reduced bone mineral density, and an increased risk of bone ...
Side effects of NETA include menstrual irregularities, headaches, nausea, breast tenderness, mood changes, acne, increased hair growth, and others. [6] NETA is a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone. [1]
Estradiol production during the menstrual cycle is 30–640 µg/d (6.4–8.6 mg total per month or cycle). The vaginal epithelium maturation dosage of estradiol benzoate or estradiol valerate has been reported as 5 to 7 mg/week. An effective ovulation-inhibiting dose of estradiol undecylate is 20–30 mg/month. Sources: See template.
A large clinical study of high to very high oral dosages of norethisterone (10 to 40 mg/day) administered for prolonged periods of time (4 to 35 weeks) to prevent miscarriage in pregnant women found that 5.5% of the women experienced mild androgenic side effects such as mild voice changes , acne, and hirsutism and that 18.3% of female infants ...
The FDA first approved the oral contraceptive in 1960. The first oral contraceptive contained 100 to 175 μg of estrogen and 10 mg of progesterone. However, at these levels significant adverse effects were seen and modern preparations contain lower levels of 30 to 50 μg of estrogen and 0.3 to 1 mg of progesterone. [49]
At that point, Enovid 10 mg had been in general use for three years and, by conservative estimate, at least half a million women had used it. [201] [205] [206] Although FDA-approved for contraceptive use, Searle never marketed Enovid 10 mg as a contraceptive. Eight months later, in February 1961, the FDA approved Enovid 5 mg for contraceptive use.
