Briellyn is a combined birth control pill. It’s got both estrogen and progestin so if you’re looking for a progestin-only pill, the mini pill might be a better option for you.
Take Briellyn every day. It comes with three weeks of active pills containing hormones and one week of inactive pills, keeping you in your daily habit. When taken consistently, Briellyn is very effective at preventing pregnancy.
Yes, Briellyn is a generic version of Ovcon 35 and is made by Glenmark Pharmaceuticals. Briellyn and Ovcon 35 are bioequivalent, which is a fancy way of saying they’ve got the same active ingredients in the same amounts. That means they’re both equally effective at preventing pregnancy and have the same interactions and possible side effects.
Since the company that makes them is different, you’re likely to see different packaging and pill colors. The price will also likely be different — generic medications are generally cheaper than their brand-name counterparts.
Briellyn changes your hormone levels, which changes how your body prepares for pregnancy every month. The two hormones it contains, norethindrone acetate and ethinyl estradiol, are synthetic versions of the progesterone and estrogen you already have in your body.
When you take hormonal birth control, you’ll be protected from pregnancy in three ways. The hormones stop ovulation, the once-monthly action where your ovaries release an egg. They also impact the lining of your uterus, which normally becomes thicker every month in preparation for the egg. Keeping the lining thin has the bonus effect of making your periods lighter and shorter. Thirdly, the hormones create a physical barrier against sperm by changing the consistency of your cervical fluid to something more difficult to swim through. Hey, whatever works, right?
