Combined pill

The combined pill is popularly known as “the pill”. Just as the name implies, it contains a combination of the artificial forms of the two major female reproductive hormones - estrogen and progesterone. The natural forms of these hormones are produced by the ovaries and also partly by the adrenal gland.

Pregnancy occurs as a result of fertilization of the ova (human egg) by the sperm, but this can be prevented through contraception. Contraception acts to prevent this process either by killing the sperm, keeping the sperm away from the ova, or preventing the release of the ova from the ovaries during ovulation.

What is the combined pill?

  • The combined pill is about 99% effective if taken properly. This implies that less than one woman in a hundred would get pregnant in a year if every of them use the pill correctly. Although there are certain contraceptives which have been found to be more effective compared to the combined pills, some include the implants and injections, IUDs and more.
  • The combined pill is usually taken for 21 days, with a daily dose of one pill after which a short 7 day break is taken, and then the pills are resumed afterwards for another 21 days. During the seven day break, you may experience some bleeding (similar to your period) but this shouldn’t bother you.
  • These pills must be taken at a selected time of the day for the 21 days and should never be missed, as this could increase your chance of getting pregnant. If you also experience severe vomiting or diarrhea during the 21 days, it may affect the effectiveness of the drug.
  • Certain drugs alter the effectiveness of the pill. Before taking drugs, ensure that you consult your doctor.
  • The combined pill may help to reduce the pain in those who experience heavy and/or periods, premenstrual syndrome (PMS), or endometriosis.
  • Some minor side effects of the combined pill include headaches, mood swings, breast tenderness and nausea.
  • It does not cause weight gain
  • It rarely gives rise to serious side effects such as cervical cancer or blood clots.
  • It is not recommended for certain women such as women with specific medical conditions, smokers above 35 years old.
  • It only effectively prevents pregnancies and provides no protection against STIs. To prevent infections, ensure you use a condom.

How does the combined pill work?

Every month, every woman’s (except those in the menopausal age and those who have not attained menarche) ovaries releases an egg (ova) with hopes that it would be fertilized. The combined pill acts to prevent this release and also causes,

  • Thickening and increased production of thick mucus within the cervix (the passage leading to your womb or uterus), making it difficult for the sperm to pass through or get access to the egg.
  • The mucosal lining of your womb (uterus) to become thin, thereby preventing implantation of already fertilized eggs (pregnancy).

The combined pills have been found to be over 99% effective when used properly, but are less effective for most women because, only a few use it correctly (the majority of these women are unable to take the pills at a specific time daily). However, there are other contraceptive methods which have been found to be more effective such as IUS, implants and injections and also IUDs.

Just like every other drug, the pills are produced by different brands but come in 3 major types

Monophasic 21-day pills

This is the most frequently used type of the combined pill. Every pack of these pills contains 21 pills, each containing an equal amount hormone in it. A pill is taken daily for 21 days, after which a short 7days break is taken. Some common examples are Microgynon, Cilest, Maervelon and Yasmine.

Phasic 21-day pills

The pack of the phasic pills usually contains 2-3 sets of differently colored pills. Each set, according to its color contains a different amount of hormone it. Just as the monophasic pills, these pills are also taken daily for 21 days and afterwards a short 7 day break is taken. The phasic pills, should be taken as instructed (according to sets) to achieve maximum effectiveness. A common example is Logynon.

Every Day (ED) pills

Unlike the monophasic and phasic pills, the ED pills contain about 28 pills, 21 of them being active pills and 7, inactive (dummy) pills. These two sets of pills are usually colored differently and can be easily identified. When taking the ED pills, a pill is taken daily for 28 days (with no 7 days break). Everyday pills should be taken in the right order to ensure effectiveness. A common example is Microgynon.

It is important that you keep to the manufacturer’s instructions of your preferred pills. You can always consult your GP, nurse or pharmacist, if you have are confused or have questions.

To achieve maximum effectiveness, you need to follow the instructions correctly. Missing your pills, taking them at wrong times or with certain medications can reduce the effectiveness.

How to take the 21-days pill

  • Each pack of pills usually comes with the days of the week marked above every pill, identify the correct day of the week and take your pills. For the phasic pills, you are required start with the first pill of the first color.
  • Select a specific time of the day and take your pills daily at the selected time until the pack is exhausted.
  • After you have completed the pills for 21 days, take a 7 day break immediately (you may get a bleed during this period).
  • On the eighth day, start a new pack (it doesn’t matter if you are still bleeding). The eighth day usually falls on the same day of the week as that, on which you started your first pill on the previous pack.

How to take the everyday pills

  • Begin with the first pill labeled “start” on the first set of pills. This set usually contains the active pills.
  • Take one pill daily in the right order, as directed and also at a specific time each day until the pack is exhausted (after 28 days).
  • Whilst taking the inactive pills, you may get a bleed (similar to your period).
  • After completing the pack, begin another -It doesn’t matter if you are still bleeding.

Starting the combined pill

Even while experiencing their menstrual cycle or period, most women can still start their pills. It is necessary that you seek the advice of a medical professional if you have just delivered, had an abortion or a miscarriage.

Sometimes, you may be required to use an extra contraceptive method when taking your first pill- this would be dependent on how far or early you are into your menstrual cycle.

Starting the combined pill on the first day of your period

Starting the combined pill on the first day of your menstruation cycle offers you complete protection against pregnancy. In this case, there would be no need for extra contraception.

Starting the combined pill on the fifth day of your cycle

If you start on the fifth day, the pills will not offer absolute protection until 7 days after you have started. Therefore, you would have to make use of extra contraceptive methods.

When starting this pill, it is important that you avoid putting yourself at a risk of getting pregnant and also ensure that you haven’t put yourself at risk already since your previous period. Carry out a pregnancy test, at least 3 weeks after your last unprotected sex, if you suspect that you are pregnant.

What you should be done if you miss a pill

Missing a pill or pills, starting a pack late or taking the pills alongside certain medications can alter its effectiveness. The risk of getting pregnant after you have missed a pill or pills would depend on

  • The time at which the pills are missed
  • The number of times you miss the pills.

There are certain steps to take, if you miss a combine pill. To find out about these steps, check here.

Vomiting and diarrhea from the pill

Vomiting within 2-3 hours after intake of your pills can affect its effectiveness. This is because the process of drug absorption may still be ongoing. If this happens, ensure you take another pill immediately and then take your next pill at the selected time.

If your illness persists, you will need to make use of extra contraception until you have recovered (and stopped vomiting).

Severe diarrhoea (with a frequency of about 6- 8 watery stools a day) can also impair absorption of the pills, thereby altering its effectiveness. If you experience this, ensure that you use extra contraceptive devices like condoms, until at least 2 days after you have recovered.

Who can make use of the combined pill?

As long as you don’t smoke or have any medical reasons or conditions preventing you from taking the pills, you can take them, even until you attain menopause.

The pill after having a baby

Women who have just had a baby can begin taking pills at least 21 days after delivery, if they aren’t breastfeeding, but would need to consult their doctor for guidance. If you do this, the pills would offer you complete and immediate protection against pregnancy.

The combined pill with other medicines

Certain medicines, when administered with the pills alter its effectiveness. A few of these drugs have been listed below. To confirm if your medications are compatible with the combined pills, you can:

  • Talk to your GP, nurse or pharmacist.
  • Read the information leaflet that you find in the packet of your medication.

The combined pill and antibiotics

Certain antibiotics such as rifampicin and rifabutin (used in the treatment of conditions such as tuberculosis and meningitis) can alter the effectiveness of the pills. However, other antibiotics do not alter its effectiveness.

If you are taking rifampicin or rifabutin, you may need to add an extra contraceptive like condoms, while on this medication. You can also consult your doctor or nurse for medical advice.

Combined pill and Epilepsy and HIV medicines and ST. John’s wort

Certain medications, called enzyme inducers interact with combine pills and affect its effectiveness. These medicines make the breakdown of these drugs by your liver faster, thereby giving the drugs little time to act. This in turn reduces its effectiveness.

Some enzyme inducers include;

  • Drugs used in treatment of epilepsy such as Carbamazepine, primidone, phenytoin, oxcarbazepine, phenobarbital and topimarate.
  • St John’s wort (a local herbal remedy)
  • Drugs used in the treatment of HIV (antiretroviral medicines)–studies reveal that the interaction that occurs between these medications and the progestin-only pills can make the both drugs unsafe and ineffective.

You may be advised by your GP or practice nurse to make use of another contraceptive instead or an extra contraceptive method while taking either of these drugs.

The risks of taking combined pills

There are certain health risks that may be associated with the use of the combined pills. However, the associated risks are small and can be outweighed by the benefits in most cases.

Blood clots

The hormone, estrogen contained in the pill is capable of causing your blood to clot easily within your blood vessels. If this occurs, it could cause

  • Deep vein thrombosis (formation of a blood clot in your leg)
  • Pulmonary embolus (formation of a mobile blood clot in your lungs)
  • Stroke
  • A heart attack

Although the risk of developing a blood clot is low, you would need to be examined and assessed by your doctor for specific risk factors, before the combined pill can be prescribed.

Sometimes, you may be advised to take the combined pills with caution if you have any of the following risk factors. Although, if you possess two or more of these risk factors, you may be advised against taking the combined pills.

You would be advised against it if you

  • are 35 years old or older
  • Is a smoker and have just quit smoking less than a year before attempted use.
  • Are extremely overweight (the risk is in women with a BMI of 35 or more, greatly outweighs the benefits).
  • have been diagnosed with hypertension
  • Have serious migraines (do not take combined pills if you experience regular and severe migraine attacks with warning symptoms such as auras).
  • Have previously had a stroke or thrombosis.
  • Have or had a close relative who younger than 45 and has or has had a blood clot.
  • Prolonged immobility- if you have been in a wheelchair or have had a leg plaster on, for a while.

Cancer

Research is presently ongoing to determine the link or connection between the combined pill and breast cancer. Some studies reveal that women who use contraception are slightly at a higher risk of developing breast cancer compared to those who don’t. However women who stop using contraceptive pills for at least 10 years, have just the same level of risk as women who have never used contraceptives.

Certain researches have revealed that there may be a link between the intake of combined pills and the chances of developing cervical cancer and a rare type of liver cancer. However, these pills may reduce your risk of developing ovarian, endometrial and colon cancer.

advice you are given and also the decisions you make.

This is because doctors and nurses work under stringent guidelines when handling, treating, advising or attending to people under the age of 16. The most they can do is try to encourage or convince you to tell your parents or caregivers, but you would not be forced to tell.

There are a few cases where, a medical professional might disclose that information to someone else. In these kinds of cases, the professional has to be sure that you may be at a risk of harm (either by someone or yourself), for example, abuse. For this to happen, the risk has to be significant. Usually, your doctor or nurse would discuss the risks and their intended actions with you before acting.
