How Opill® works

Opill® is a progestin-only birth control pill (also known as a POP or mini pill). It contains only one hormone, progestin, and is estrogen-free.

Opill® works by thickening the cervical mucus, which helps block sperm from reaching the egg. It may also prevent your ovaries from releasing eggs.

Opill® is 98% effective at preventing pregnancy when taken at the same time every day. It starts working within 48 hours after you take your first pill, so make sure to keep using a barrier method like condoms for the first two days to prevent pregnancy, or if you miss or are late taking a pill.

Who is Opill for?
Opill® is suitable for most* women and people capable of becoming pregnant
Opill® is an oral contraceptive that contains only one hormone, progestin. This makes Opill® suitable for most* individuals who can become pregnant – even those with certain conditions such as high blood pressure, who are breastfeeding, perimenopausal, smokers, or experience migraines. Unlike many other birth control pills, Opill® does not contain estrogen. This is beneficial for individuals with medical conditions or life circumstances that prevent them from taking estrogen-based contraceptives.
The use of Opill® is not restricted by age. As long as you have started menstruating, it is safe for you to use.
Additionally, Opill® is a great alternative for those without health insurance or frequent access to medical services, as it can be purchased over the counter without a prescription.
*If you currently have or have previously had breast cancer, you should not take Opill®. Use as directed.

FAQs
How does Opill® work?
Opill® works by thickening your cervical mucus, which helps to block sperm from getting to an egg. In addition, Opill® may prevent ovulation, but not in all cycles. You must take it at the same time every day to prevent pregnancy. Opill® is effective from 48 hours after you begin taking it, so make sure to use a barrier method during the first two days of starting the pill to prevent pregnancy, or if you miss or are late taking a pill.
Is Opill® the same as other birth control pills?
Opill® is a progestin-only birth control pill (sometimes referred to as POPs or the mini pill). Many birth control pills on the market contain a combination of estrogen and progestin. Opill® only contains one type of hormone (progestin) and is estrogen-free. Like all daily oral contraceptives, Opill® should be taken once a day, at the same time.
How is Opill® different than Plan B?
Opill® is a birth control pill that is taken every day to prevent pregnancy. A morning after pill like Plan B is only meant to be used within three days in cases of unprotected sex or if other methods of birth control fail and NOT as a regular form of birth control.
Do not use if you have or ever had breast cancer; if you are already pregnant or think you may be pregnant; together with another birth control pill, vaginal ring, patch, implant, injection, or an IUD (intra-uterine device); as an emergency contraceptive (morning after pill). This product does not prevent pregnancy when used after unprotected sex; or if you are male.
Read product labeling before use.
