Pregnancy can result from sexual intercourse but there are many contraceptive methods available to prevent conception. Loestrin is a combined female birth control pill (or ‘The Pill’) which means that it contains artificial progestogen and oestrogen ingredients. This hormonal contraceptive pill works by preventing ovulation, thickening the mucus in the neck of the womb to make it harder for sperm to reach the egg and it thins the lining of the womb to lessen the chance of a fertilised egg being able to implant. Simply taking one Loestrin tablet per day, around the same time, will give you 99% effective protection from unwanted pregnancy.

Combined Pill

The combined oral contraceptive pill is usually just called “the pill”. It contains the female hormones oestrogen and progesterone, which women produce naturally in their ovaries.
The Combined pill is over 99% effective at preventing pregnancy.

The usual way to take the pill is to take one every day for 21 days, then stop for seven days, and during this week you have a period-type bleed. You start taking the pill again after seven days.
You need to take the pill at around the same time every day. You could get pregnant if you don’t do this, or if you miss a pill, or vomit or have severe diarrhoea.

Some medicines may make the pill less effective. Check with your doctor if you’re taking any other tablets.
If you have heavy periods or painful periods, PMS (premenstrual syndrome) or endometriosis the combined pill may help.

The pill does not protect against sexually transmitted infections (STIs), so using a condom as well will help to protect you against STIs.

How the combined pill works

1) prevents the ovaries from releasing an egg each month (ovulation).
2)thickens the mucus in the neck of the womb, so it is harder for sperm to penetrate the womb and reach an egg
3)thins the lining of the womb, so there is less chance of a fertilised egg implanting into the womb and being able to grow

There are many different brands of pill, made up of three main types:

Monophasic 21-day pills
This is the most common type. Each pill has the same amount of hormone in it. One pill is taken each day for 21 days and then no pills are taken for the next seven days. Microgynon, Marvelon, Yasmin and Cilest are examples of this type of pill.

Phasic 21-day pills
Phasic pills contain two or three sections of different coloured pills in a pack. Each section contains a different amount of hormones. One pill is taken each day for 21 days and then no pills are taken for the next seven days. Phasic pills need to be taken in the right order. Logynon is an example of this type of pill.

Every day (ED) pills
There are 21 active pills and seven inactive (dummy) pills in a pack. The two types of pill look different. One pill is taken each day for 28 days with no break between packets of pills. Every day pills need to be taken in the right order. Microgynon ED is an example of this type of pill.

Follow the instructions that come with your packet. If you have any questions, ask your GP, practice nurse or pharmacist.

What to do if you miss a pill

If you continue to be sick, keep using another form of contraception until you’ve taken the pill again for seven days without vomiting.

Who can use the combined pill

If there are no medical reasons why you cannot take the pill, and you don’t smoke, you can take the pill until your menopause. However, the pill is not suitable for all women. To find out whether the pill is right for you, talk to your GP, practice nurse or pharmacist.

You should not take the pill if you:

are pregnant
smoke and are 35 or older
stopped smoking less than a year ago and are 35 or older
are very overweight
take certain medicines (ask your GP or a health professional at a contraception clinic about this)

You should also not take the pill if you have (or have had):

thrombosis (a blood clot) in a vein, for example in your leg or lungs
stroke or any other disease that narrows the arteries
anyone in your close family having a blood clot under the age of 45
a heart abnormality or heart disease, including high blood pressure
severe migraines, especially with aura (warning symptoms)
breast cancer
disease of the gallbladder or liver
diabetes with complications or diabetes for the past 20 years

Risks of taking the combined pill

There are some risks associated with using the combined contraceptive pill. However, these risks are small and, for most women, the benefits of the pill outweigh the risks.

Blood clots
The oestrogen in the pill may cause your blood to clot more readily. If a blood clot develops, it could cause:

deep vein thrombosis (clot in your leg)
pulmonary embolus (clot in your lung)
heart attack
The risk of getting a blood clot is very small, but your doctor will check if you have certain risk factors that before prescribing the pill.

The pill can be taken with caution if you have one of the risk factors below. It is unlikely you would be advised to take it if you have two or more risk factors.
These include:

being 35 years old or over
being a smoker or having quit smoking in the past year
being very overweight (in women with a BMI of 35 or over, the risks of using the pill usually outweigh the benefits)
having migraines (you should not take the pill if you have severe or regular migraine attacks, especially if you get aura or a warning sign before an attack)
having high blood pressure
having had a blood clot or stroke in the past
having a close relative who had a blood clot when they were younger than 45
being immobile for a long time – for example, in a wheelchair or with a leg in plaster


Product Description

What is Loestrin?

Loestrin (Norethisterone and ethinylestradiol) is a combined oral contraceptive used to prevent pregnancy and is up to 99% effective.

It works in three different ways:

1) they prevent the release of an egg from your ovaries.

2) these hormones work to thicken the fluid (mucus) in your cervix (resulting in the sperm experiencing difficulties entering the womb).

3)the lining of your womb is prevented from becoming thick enough for an egg to grow in it.

Loestrin is not suitable for all women and so it is important to understand both, the benefits and the risks of this medication before taking it. It is Not advised for women who are over the age of 35 and smokers.

Loestrin is can be over 99% effective in preventing pregnancy if taken in the correctly, as directed on the patient information leaflet supplied with the medication.

How to Use Loestrin

Loestrin comes in strips of 21 pills, each marked with a day of the week.

  • Take your pill at the same time every day.
  • Start by taking a pill marked with the correct day of the week.
  • Follow the direction of the arrows on the strip. Take one pill each day, until you have finished all 21 pills.
  • Swallow each pill whole, with water if necessary. Do not chew the pill.

Then have seven pill-free days

After you have taken all 21 pills in the strip, you have seven days when you take no pills.

Within a few days of taking the last pill from the strip, you should have a withdrawal bleed like a period. This bleed may not have finished when it is time to start your next strip of pills.

You don’t need to use extra contraception during these seven pill-free days – as long as you have taken your pills correctly and start the next strip of pills on time.
