Birth Control Pill
To put off parenthood or just to avoid unwanted pregnancies, many couples have made birth control pills a part of their daily routine. In fact, this contraception if one the most popular forms of female birth control. These contraceptive pills can be taken orally and are very effective at preventing pregnancy.
What are Birth Control Pills?
There are mainly two kinds of pills that you will find on the market. One type of birth control pill has artificial estrogen and progesterone while the other is comprised of just progesterone. These usually come in a pack of 21 or 28 pills and have to be taken daily at a particular time of the day. Some newer brands of pills, though, require you to take the hormonal pills for 90 or more consecutive days. To get the contraceptive pill, you will need a prescription from your doctor.
How do the Pills Work?
When you take an oral combination pill (those with both estrogen and progesterone), the hormones present block the release of an egg from the ovary. This is the primary method through which the pill works. The pill also helps in thickening the cervical mucus so that it becomes harder for sperm to move and fertilise an egg in the fallopian tube.
Progesterone-only pills generally do not prevent ovulation but instead thickens the cervical mucus to prevent fertilisation from occurring. Both these kinds of pills may also thin the uterine lining, which can prevent implantation from taking place if an egg is fertilised.
Birth control pills offer no protection against sexually transmitted diseases.
Who Can Use Them?
Most healthy women can use oral contraceptive pills to avoid pregnancy. However, there are instances where this method may not be suitable and other birth control options may be better. Some typical cases where you should not use birth control pills include:

Effectiveness of Pills
Research and use by many women has shown that birth control pills are as much as 99.9% effective in preventing pregnancy when used perfectly. Perfect use refers to taking the pill at the exact same time every day (so that your hormone levels stay consistent) and not forgetting any pills. However, with typical use, the pill may be as low as 92% effective. Typical use means that you do not take the pill at the exact same time each day and that you might sometimes forget to take a pill.
It has been seen that certain drugs like antibiotics, anti-fungals, anti-HIV protease inhibitors, and anti-seizure medications affect the efficacy of birth control pills. Therefore it is always better to ask your physician about the drugs you can take along with the pill. If you are being prescribed a drug, make sure to mention to the doctor that you are taking the birth control pill.
Sometimes vomiting and diarrhoea may also lessen the effectiveness of the contraceptives. Pills can also fail to prevent pregnancy if you miss one or more doses or take an irregular dosage. If you have been sick, are using a medication that can interfere with the pill or miss a dose, consider others methods of birth control, like a condom, until you get your period to help prevent pregnancy.
How to Use the Pills
If you are prescribed 28-day birth control pills, your pill pack will consist of 21 days worth of hormonal pills and seven days of sugar pills. During the seven days of the sugar pills, you will get your period. Women using 21-day birth control pill packs will take only hormonal pills for 21 consecutive days before stopping their pill for one week. During this pill-free week, you will get your period. At the end of the pill-free or sugar-pill week, you will start another pack of hormonal pills. Women on other forms of birth control pills may take the hormonal pills for a longer period of time before breaking for a period.
It is important to take a pill at the same time everyday particularly if you are using the progesterone-only pill. If you delay the time by 3 hours or more, you might have to use another effective birth control method in addition to your pill. Linking your pill taking to a daily activity, like eating breakfast or brushing your teeth, will help you make it a part of your daily routine. Other women find it helpful to set a watch alarm so that they never forget to take their pill.
If you do forget to take a pill, take the missed pill as soon as you remember and continue with your regular schedule. If you miss two or more pills, consult the instructions that come with your birth control pills.
Although the pill is usually effective as soon as you start taking it, it is generally recommended to use a secondary contraceptive method for the first week to month of use.
