Ovcon Uses

High-Dose Estrogen Contraceptives

Ovcon 50 (but not Ovcon 35) contains a high dose of estrogen (ethinyl estradiol), compared to most other birth control pills that are currently available. Any birth control pill with 50 mcg or more of ethinyl estradiol is considered a high-dose estrogen contraceptive (Ovcon 50 contains 50 mcg of ethinyl estradiol per tablet). When birth control pills first came out, they had much higher estrogen doses, compared to today's birth control pills. Over the years, new birth control pills have gradually reduced the estrogen dose, as estrogen is responsible for many of the dangerous problems associated with birth control pills (like heart problems, blood clots, and strokes).
Although these new, low-dose birth control pills are very effective, they tend to provide less cycle control. This means that there is often more bleeding between periods (breakthrough bleeding) and, sometimes, heavier periods with low-dose pills. The high-dose birth control pills seem to control the growth of the endometrium (the lining of the uterus that is shed with bleeding) more than the low-dose pills.
Because the higher dose of estrogen in Ovcon 50 increases the risk of many serious side effects, you should only take Ovcon 50 if your healthcare provider thinks that it is the best option for your situation. If you do not have any problems with regular or low-dose birth control pills, you should not take Ovcon 50.

How Does Ovcon Work?

Ovcon is a "combined" oral contraceptive, which means that it contains two different types of hormones. It contains both an estrogen (ethinyl estradiol) and a progestin (norethindrone). Combined oral contraceptives are the most common type of birth control pills used today. Generally, combined oral contraceptives are more effective than progestin-only birth control pills.
Most importantly, the hormones in Ovcon prevent pregnancy by stopping ovulation (the maturation and release of eggs from the ovaries). However, it also works to prevent pregnancy in two other, minor ways. Ovcon changes the cervical mucus (the fluid of the cervix, which is the lower, narrow part of the uterus that is connected to the vagina), making it more difficult for sperm to enter the uterus. Lastly, Ovcon alters the lining of the uterus (called the endometrium), making it less receptive to an embryo.
