Birth control tablets are a well-known and efficient form of contraception. However, some circumstances, such as skipping pill days, vomiting, and taking certain medicines, may decrease the pill’s efficacy and result in unplanned pregnancies.
Let’s take a look at how successful the birth control pill is, as well as five reasons why it may fail. We also discuss how to avoid pill failure and other early pregnancy symptoms.
What is the pill’s efficacy?
The combination pill includes hormones that inhibit ovulation, or the release of an egg by the ovaries for fertilisation. Another kind of tablet, known as a minipill, thickens cervical mucus and thins the uterine lining, lowering the chance of sperm reaching an egg.
When used properly and on all pill days, the birth control pill is highly effective. The Centers for Disease Control and Prevention (CDC) claims that the tablet is 99.7 percent effective when used correctly. This implies that fewer than one in every hundred women who use the pill will get pregnant within a year.
The pill’s efficacy, however, is 91 percent when used as directed. This implies that about 9 out of every 100 women who use the pill will get pregnant within a year.
The following are five causes of pill failure.
Although the birth control pill is usually highly effective, some circumstances may decrease its efficacy and result in unplanned pregnancy. Among them are:
Taking a day off
To be most effective, the tablet should be taken daily, according to the manufacturers. If a person skips a day, their hormone levels may not be stable enough to avoid conception.
Other birth control techniques may be more suitable if a person finds it difficult to take the pill on a regular basis. A doctor or gynaecologist can advise you on the many contraceptive methods available.
Vomiting
When taking the tablet, a person may feel sick at times. When a person vomits, the pill may come back up or they may not completely absorb it.
Anyone who vomits immediately after taking the pill should take another tablet as soon as feasible and then continue with their regular schedule.
The tablets are not taken at the same time every day
A person should not only take birth control pills on a regular basis, but also at the same time each day. This allows them to maintain more constant hormone levels.
Every day, the minipill should be taken within the same three-hour time frame. If a person misses their window, they should use a backup form of birth control for the following two days or avoid having intercourse.
Many individuals set a daily alarm to remind them to take their medication at the proper time each day.
Not immediately beginning a new pack
It is essential to begin a fresh pack of tablets the day after the prior one has been finished. However, it is possible that a person’s new package is not yet available. If you skip a few days between packets, the pill will be less helpful in preventing pregnancy.
The CDC recommends that anybody who misses two or more tablets in a run use a backup contraceptive technique or refrain from sexual activity until they have taken the birth control pill for seven days in a row.
Medications that disrupt the pill’s action
Some drugs may reduce the effectiveness of the tablet. Antibiotics, such as rifampicin, and antifungal medications, such as griseofulvin, are examples of medications.
A person should utilise backup contraception while taking these medicines and for the next 48 hours after the course is completed.
Other long-term medicines and supplements may potentially impair the effectiveness of birth control tablets. Among them are:
• medicines used to treat epilepsy, such as phenobarbital, phenytoin, and carbamazepine
• HIV-treating antiviral medicines
Preventing Pill Failure: Some Points to Consider
Birth control pills are very effective if used properly and on all tablet days. Preventing unexpected pregnancies while on the pill is made easier with the following tips:
By carefully reading and adhering to the directions on the package
• Taking the tablet every day at the same time
• utilising a period tracking software that sends pill reminders
• Obtaining a new medication pack at least one week before the previous pill pack expires
• Always take missing medications as soon as you remember.
• utilising a backup form of contraception, such as a condom, if a person forgets to take two or more tablets in a succession.
If a person is worried about not being able to take their tablets on a regular basis, they should talk to their doctor or gynaecologist about alternative methods of birth control. An intrauterine device, or IUD, is one alternative that does not need taking a pill every day.
Pregnancy symptoms early on
If a person is worried about contraceptive failure and the potential of pregnancy, they should consult with their doctor. However, there are certain early indications of pregnancy that you should be aware of:
• Bloating. Bloating is often a symptom of premenstrual syndrome, but it may also be an indication of early pregnancy.
Tenderness in the breast Breast soreness may occur early in pregnancy due to high levels of the hormones oestrogen and progesterone. Some women may also experience sensations like tingling, heaviness, or breast fullness.
• Light spotting. When an egg adheres to the uterine lining, a little amount of bleeding or spotting may occur. Spotting that occurs outside of a normal menstrual cycle may be an early sign of pregnancy.
• Excessive tiredness that is not explained. Even in the early stages of pregnancy, hormonal changes in the body may make a person feel fatigued.
• More frequent urination early in a woman’s pregnancy, hormonal changes may increase her urge to urinate.
Anyone who suspects she or he is pregnant should consider using an at-home pregnancy test. These tests have grown more sensitive to a person’s hormone levels and more accurate in identifying pregnancy in its early stages.
However, if a person does an at-home pregnancy test too soon or fails to follow the directions properly, the results may be unreliable. The United States Food and Drug Administration (FDA) recommends taking the test 1–2 weeks following the first missing period for the most accurate results.
FINAL VERDICT
While birth control tablets are usually highly successful, they may sometimes fail to prevent births if used incorrectly and regularly.
Anyone who has questions regarding the efficacy or convenience of their contraceptive technique should see a doctor.
If a person misses more than one pill, they should utilise a backup contraceptive technique for at least 7 days before resuming pill-taking.
