Description:

Ethinylestradiol is a man-made form of the naturally occurring female hormone called oestrogen.
It is prescribed to treat period (menstrual) problems, and also to help ease menopausal symptoms. It is usually prescribed alongside another female hormone called a progestogen.

Ethinyl estradiol also sometimes written as ethinylestradiol, ethynyl estradiol, or ethinyl? Stradiol, is a derivative of 17β -estradiol (E2), the major endogenous estrogen in humans. EE is an orally bioactive estrogen used in many formulations of combined oral contraceptive pills. It is one of the most commonly used medications for this purpose.

Estinyl was a preparation of EE alone that was used for the management of menopausal symptoms and female hypogonadism.
EE is released into the environment as a xenoestrogen from the urine and feces of people who take it as a medication.


Application :

When estrogen is prescribed for a woman with a uterus, progestin should also be initiated to reduce the risk of endometrial cancer. A woman without a uterus does not need progestin. Use of estrogen, alone or in combination with a progestin, should be with the lowest effective dose and for the shortest duration consistent with treatment goals and risks for the individual woman. Patients should be reevaluated periodically as clinically appropriate (e.g., 3-month to 6-month intervals) to determine if treatment is still necessary. For women who have a uterus, adequate diagnostic measures, such as endometrial sampling, when indicated, should be undertaken to rule out malignancy in cases of undiagnosed persistent or recurring abnormal vaginal bleeding.

Short-term cyclic use for treatment of moderate to severe vasomotor symptoms, vulval and vaginal atrophy associated with the menopause, the lowest dose and regimen that will control symptoms should be chosen and medication should be discontinued as promptly as possible.
Attempts to discontinue or taper medication should be made at 3- to 6-month intervals. The usual dosage range is 1 to 5 mg injected every 3 to 4 weeks.

For treatment of female hypoestrogenism due to hypogonadism 1.5 to 2 mg injected at monthly intervals.
