Birth Control Pills: Everything You Need to Know

Last Updated on June 9, 2023 by lizzy

Birth control pills, also known as oral contraceptives, are pharmaceutical formulations that contain synthetic hormones to prevent pregnancy.

How Birth Control Pills Work

• Work by suppressing ovulation, which prevents the release of eggs from the ovaries.
• Help regulate the menstrual cycle and create an environment in the reproductive system that makes it difficult for sperm to fertilize an egg.

Types of Birth control pills

Combination Pills

They contain synthetic forms of estrogen and progestin hormones. They are the most commonly used type of birth control pills.

Mechanism of Action

Combination pills work by suppressing ovulation, thickening cervical mucus, and thinning the lining of the uterus to prevent fertilization and implantation.

Popular Brands and Formulations

Examples of combination pills include Yaz, Yasmin, Ortho Tri-Cyclen, and Lo Loestrin Fe. These pills may differ in hormone dosages and variations.

Progestin-Only Pills

Progestin-only pills, also known as mini-pills, contain only a synthetic form of progestin hormone. They are suitable for individuals who cannot or prefer not to take estrogen.

Mechanism of Action

Work by thickening cervical mucus, thinning the lining of the uterus, and inhibiting ovulation in some cases.

Popular Brands and Formulations

Examples of progestin-only pills include Micronor, Camila, and Nora-BE. These pills are taken daily without a break, unlike combination pills.

Extended Cycle Pills

They are designed to reduce the frequency of menstruation. They typically contain a combination of estrogen and progestin hormones.

Benefits and Considerations

Extended cycle pills can provide benefits such as reduced menstrual symptoms and fewer periods per year. However, they may require adjustment and consultation with a healthcare provider.

Popular Brands and Formulations

Examples of extended cycle pills include Seasonale, Seasonique, and Jolessa. These pills are taken continuously for an extended period, typically with a break every three months.

Emergency Contraceptive Pills

Also known as “morning-after pills,” are used to prevent pregnancy after unprotected intercourse or contraceptive failure.

Mechanism of Action

Emergency contraceptive pills primarily work by preventing or delaying ovulation, interfering with fertilization, or inhibiting implantation.

Types and Availability

Commonly available emergency contraceptive pills include Plan B One-Step, Next Choice, and Ella. Some require a prescription, while others are available over-the-counter.

Factors Influencing Effectiveness

Consistency of Use

The effectiveness of birth control pills relies heavily on consistent daily use without missing any doses.

Timing and Adherence

Taking the pill at the same time each day is essential to maintain hormone levels and maximize its contraceptive effects.

Individual Variations

Factors such as metabolism, interactions with other medications, and individual differences in hormone sensitivity can impact the effectiveness of birth control pills.

Effectiveness Rates of Birth Control Pills

Perfect Use vs. Typical Use

Effectiveness rates are often reported based on perfect use, which means using the pill correctly and consistently. However, in real-world scenarios, the typical use may vary.

Pearl Index and Failure Rate

The Pearl Index is a measure used to calculate the number of pregnancies per 100 women using a particular method of contraception for a year. It provides insight into the failure rate.

Comparative Analysis

Comparing the effectiveness rates with other contraceptive methods can help individuals make informed choices based on their needs and preferences.
