Oral contraceptive pills, commonly known as birth control pills, rank second only to sterilization as a method of birth control. These pills are a popular and effective way to prevent pregnancy. This article explores what oral contraceptives are, how they work, and their potential side effects.

What are Oral Contraceptives?

Oral contraceptives are medications taken by women to prevent pregnancy. Examples of commonly used oral contraceptive pills include Femilon and Marvelon. These pills are composed of synthetic sex hormones that mimic the natural hormones in a woman’s body during her reproductive cycle.

Composition of Oral Contraceptive Pills:

– Oral contraceptive pills are made from synthetic hormones, which are chemically similar to naturally secreted hormones in the female body.

– These synthetic hormones are derived from substances found in plant materials, such as Mexican yams.

How Do Oral Contraceptive Pills Work?

The primary function of oral contraceptives is to prevent ovulation, the process by which an ovum (egg) is released from the ovaries during the menstrual cycle. Here’s how they work:

Simulation of Pregnancy:

– The synthetic hormones in the pills simulate the hormonal state of pregnancy.

– This tricks the body into thinking it is already pregnant, thereby suppressing ovulation.

Suppression of Ovulation:

– By preventing the release of an ovum, the chances of fertilization by male sperm are significantly reduced.

– Menstruation is delayed as long as the pills are taken.

Regimen of Intake:

– Typically, oral contraceptive pills are taken daily for 21 days.

– After completing the 21 pills, there is a break during which normal menstruation occurs.

– The cycle then repeats with a new pack of pills after the menstruation period.

Because no ovum is released during the period the pills are taken, the likelihood of pregnancy is very low. Oral contraceptives are generally close to 100% effective when taken correctly. However, human errors, such as missing a pill, can slightly reduce their effectiveness.

Side Effects of Oral Contraceptive Pills

While oral contraceptives are highly effective, they can have side effects. Some of the common and serious side effects include:

Bleeding and Cramps:

– Some women may experience breakthrough bleeding or spotting between periods.

– Cramps and other menstrual-like symptoms can also occur.

Hypertension:

– Oral contraceptives can increase blood pressure in some women.

– Women with a history of hypertension should use these pills under medical supervision.

Neurologic Disorders:

– There can be an increased risk of neurological issues, including migraines and other headaches.

Thromboembolism:

– This condition involves the blocking of an artery or vein by a blood clot.

– Women taking oral contraceptives have a higher risk of developing blood clots.

Precautions and Recommendations

– Medical Supervision:

– Women with high blood pressure or a history of circulatory disorders should consult a healthcare professional before using oral contraceptives.

– Regular check-ups are recommended to monitor any adverse effects.

Missed Pills:

– If a pill is missed, it should be taken as soon as remembered, and the next pill should be taken at the regular time. Missing a pill can slightly increase the risk of pregnancy.

Oral contraceptives are a convenient and reliable method of birth control. However, like all medications, they come with potential risks and side effects. Women should make informed decisions and consult with healthcare providers to ensure safe and effective use.

Oral contraceptive pills provide an effective means of preventing pregnancy, but it’s important to understand their usage, benefits, and potential risks. By staying informed and consulting healthcare providers, women can make the best choices for their reproductive health.
