How effective is Opill OTC birth control?

Official answer

by Drugs.com

Opill is 91% effective at preventing pregnancy with typical (real world) use and 98% effective when used perfectly (as in clinical studies). As with any birth control method, Opill does not prevent pregnancy all of the time.

Typical use of progestin-only pills like Opill results in 91% effectiveness, meaning 9 in 100 women will become pregnant in one year of using a progestin-only pill, according to ACOG.

Perfect use results in 98% effectiveness, meaning 2 in 100 women will become pregnant in one year of using Opill.

When used as directed, Opill is expected to be the most effective form of over-the-counter birth control. It is more effective than the condom or spermicide, other over-the-counter options.

In addition, the FDA has stated the product can be used by consumers safely and effectively by following the nonprescription Drug Facts labeling, without any assistance from a healthcare provider.

Opill is NOT for use as an emergency contraceptive and will not prevent pregnancy after unprotected sex.

If you have questions about how to take Opill, refer to the Drug Facts Label and consumer information leaflet found with your pack, or ask your doctor or pharmacist.

The over-the-counter (OTC) version of Opill is the same as the prescription birth control product that contains norgestrel.

When Opill becomes available, it is expected to be the most effective form of over-the-counter birth control. It is more effective than condoms or spermicides, commonly used over-the-counter options. Opill is expected to be available in the US in the early part of 2024 in pharmacies and other retail stores. It will not require a visit to a healthcare provider.

However, Opill is NOT for use as an emergency contraceptive and will not prevent pregnancy after unprotected sex. Oral contraceptives like Opill do not protect against HIV, AIDS and other sexually transmitted diseases (STDs). Use condoms to prevent STDs.

Opill is an oral contraceptive that is taken by mouth every single day, with no breaks between pill packs. It works best when taken at the same time every day. If you take a pill late, and especially if you miss a pill, you are more likely to get pregnant.

Opill is a progestin-only pill (POP), often referred to as a “mini-pill”. It does not contain estrogen, another hormone also found in combination birth control pills.

The FDA has stated the product can be used safely and effectively by the public when following the nonprescription Drug Facts labeling, without assistance from a healthcare provider.

What if I miss a tablet of Opill?

If you take a tablet more than 3 hours late or miss a tablet on 1 or more days, you must use extra contraceptive protection (condoms or another form of barrier contraception) every time you have sex for the next 2 days (48 hours)

You will also need to use extra contraceptive protection every time you have sex for the next 2 days (48 hours) after you start your first pack or if you vomit or have severe diarrhea within 4 hours of taking a tablet.

If you have questions about how to take Opill, refer to the Drug Facts Label and consumer information leaflet found with your pill pack, or ask your doctor or pharmacist.
