How effective are the birth control pills?

Written by Janna Mustafina MSN, FNP-C








Birth control pills (also called "the pill") are the medications that contain hormones to prevent ovulation and, therefore, prevent pregnancy.  Females take one pill by mouth every day. They are 99% effective. They are most effective if taken at the same time of the day (or within 3 hours time window).  More than 3 hours window is considered being late with the pill schedule. 


How does the pill work?

These pills contain estrogen and/or progestin. Both hormones are released into your body to prevent ovulation.  How does "the pill" work? 

  • They stop ovulation

  • They thick the cervical mucus to create a plug (door) to prevent sperm from entering the uterus

  • They thin the uterus lining so an egg is less likely to attach and get fertilized by the sperm.

Types of birth control pills:


Birth control pills can be divided into 2 main categories:

 - combined hormonal contraceptives (CHC) 

 -  progestin-only pills or "mini-pills" (POPs)

Those factors can be the cost, acne control, chewable or to swallow, skipping periods, less spotting, lower risk of nausea or belly bloating, shorten or skipping periods. Once the provider knows what factors are important to you - she/he will propose you the best choice for your birth control.
