Ethinylestradiol is a synthetic form of the female hormone estrogen. It is commonly used in combination with another hormone, progestin, in oral contraceptives (birth control pills) to prevent pregnancy. Ethinylestradiol tablets are taken orally once a day, usually for 21 days, followed by a 7-day break during which no tablets are taken.
Ethinylestradiol can also be used to treat certain conditions such as menstrual disorders, endometriosis, and menopausal symptoms. It works by inhibiting ovulation (the release of an egg from the ovary) and thickening the cervical mucus, making it more difficult for sperm to reach the egg.
The dosage of ethinylestradiol tablets will depend on the individual's age, weight, and medical condition. It is important to take this medication exactly as prescribed by your healthcare provider.
Common side effects of ethinylestradiol tablets include nausea, breast tenderness, mood changes, and breakthrough bleeding (light spotting or bleeding between periods). In rare cases, ethinylestradiol can also cause more serious side effects such as blood clots, stroke, or heart attack.
It is important to note that ethinylestradiol tablets can interact with other medications, so it is important to disclose all medications and medical conditions to your healthcare provider before starting treatment with this medication. If you experience any unusual symptoms after taking this medication, you should contact your healthcare provider immediately.
