Is 'Opill' A Continuous Birth Control?
In our latest question and answer, our pharmacist discusses the new over-the-counter birth control pill and how it is dosed.
I heard about the recent approval of the Opill birth control that I can get over the counter. Is it a continuous birth control?
Jul 13, 2023- Opill is a continuous progestin-only birth control pill that you take every day without breaks, unlike combination pills that have pill-free intervals.
- Because Opill contains only progestin and no estrogen, it requires strict adherence to your daily dosing schedule and missing even a few hours can decrease its effectiveness.
- Opill may result in lighter or fewer periods but can also cause irregular spotting and breakthrough bleeding more often than combination birth control pills.
Quick Answer
Yes, Opill is a continuous birth control, meaning there is no 'pill-free' interval like many birth control products have. You take one pill every day at the same time, continuously.
Detailed Answer
Opill is a brand of progestin-only birth control pill, also known as a 'mini-pill' or POP (progestin-only pills). Unlike combination birth control pills that contain both estrogen and progestin, Opill only contains progestin and is estrogen-free.
The active ingredient in Opill is norgestrel, which is a synthetic progestin, which means it mimics the effects of progesterone in the body.
When we talk about "continuous" in the context of birth control pills, it refers to taking the active pills continuously, without a break in between packs (i.e., a pill-free interval). With continuous birth control pills like Opill, you take the active pills every day, including during your menstrual cycle, without taking inactive or placebo pills that are often found in combination pills.
Continuous use of progestin-only pills like Opill can help provide ongoing contraception and may result in lighter or fewer periods. However, there are some downsides of progestin-only pills when compared to combined hormone pills.
For one, they are less forgiving if you miss a dose. In order to maintain a high level of protection against pregnancy, progestin-only pills necessitate strict adherence to a daily dosing schedule. Deviating from the recommended timing, even a few hours, or missing pills, can decrease their effectiveness.
Additionally, progestin-only pills have a higher incidence rate of certain side effects, such as irregular, unpredictable spotting and breakthrough bleeding, when compared to combined hormone pills.
Overall, though Opill is available over-the-counter, I suggest you speak with your doctor regarding whether or not it is the best birth control choice for you.
