Notes and sources
Notes: All aqueous suspensions are of microcrystalline particle size. 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: Main/General: [34][35][36][37][38][39][40][41][42] Miscellaneous: [43][44][45] | |||||

The following dosages for estradiol in the form of aqueous suspension injected intramuscularly, or pellets implanted subcutaneously, are recommended by a leading maunfacturer: Menopausal syndrome.—In average cases, 1 mg. intramuscularly 2 or 3 times weekly for 2 or 3 weeks; in more severe cases, 1 to 1.5 mg. Thereafter dosage is reduced to the minimum requirement, usually within the range of 0.5 to 1 mg. of estradiol twice weekly.
