Explanation

Opill is a type of birth control pill that contains only progestin, which is a hormone used to prevent pregnancy. According to the medical literature, progestin-only pills like Opill are effective when taken correctly. This means taking the pill every day at the same time.

How It Works

  • Progestin: This hormone helps stop the release of an egg from the ovary.
  • Thickens Cervical Mucus: It makes it harder for sperm to reach any egg that might be released.

Effectiveness

  • High Effectiveness: When used perfectly, Opill is very effective at preventing pregnancy.
  • Typical Use: Even with typical use, which means not always taking it at the exact same time, it is still quite effective.

Availability

  • Over-the-Counter: Opill is available without a prescription, making it easier for many people to access.

Remember, taking the pill at the same time each day is important for it to work well. If you have questions about using Opill or other birth control methods, it's a good idea to talk to a healthcare provider.
