What NORIDAY is used for
NORIDAY is a birth control pill commonly known as a "progestogen-only" pill or "mini pill". NORIDAY is usually given to women
who are unable to take other types of birth control pills (oral contraceptives) or use intrauterine devices (IUDs).
NORIDAY causes changes to the mucus of the cervix and the lining of the womb and affects the hormonal control system of the
body, which may all contribute to the birth control (contraceptive) action.
The effectiveness of the "progestogen-only" pill is lower than that of other birth control pills.
If taken according to directions it is expected that if 100 women used the progestogen-only pill for 1 year approximately
4 pregnancies may occur compared to less than 1 pregnancy in women using an oral contraceptive containing an oestrogen and
NORIDAY (like all oral contraceptives) is intended to prevent pregnancy. It does not protect against HIV infection (AIDS)
and other sexually transmitted diseases.
NORIDAY 28 day is only available on a prescription from your doctor.
This medicine is prescribed for you and should not be given to others.
Before you start to take NORIDAY
When you must not take it

If you have or have had any of these problems, do not take NORIDAY until you have talked to your doctor.
Do not take it if
you have had a stroke or heart attack.
you have or have had inflammation, infection or clotting in any blood vessel(s), including a clot in the lung.

swelling of the face, lips or tongue which may cause difficulty in swallowing or breathing
hives, itching or skin rash
Tell your doctor about any existing medical condition as this may be affected by taking the birth control pill.
Do not take NORIDAY if the packaging is torn or shows signs of tampering.
Before you start to take it
You must tell your doctor if:
you are a heavy smoker (15 or more cigarettes per day), especially if you are aged over 35 years.
Oral contraceptives increase your risk of having a stroke or heart attack. Smoking while taking oral contraceptives further
increases this risk.
you have kidney or heart disease.
you have high blood pressure.
you have high cholesterol.
you have diabetes.
you have epilepsy.
you have asthma.
you have migraine.
you have or have had depression.
you are lactose intolerant. This medicine contains lactose.
Taking other medicines
Tell your doctor or pharmacist if you are taking any other medicines, including any that you buy without a prescription from
your pharmacy, supermarket or health food shop.
Some medicines may interfere with the effectiveness of NORIDAY. These include medicines such as:
Rifampicin for the treatment of tuberculosis.
Medicines used to treat epilepsy or fits such as barbiturates, primidone, phenytoin and carbamazepine.
Antibiotics such as ampicillin.
Anti-fungal agents such as griseofulvin.
Antacids used for indigestion or heartburn
Antacids may decrease the absorption of NORIDAY.
If you need to take an antacid while on NORIDAY, you should take these medicines at least 2 hours apart.
Your doctor will advise you if you need to take extra contraceptive precautions for the time that you are taking these medicines.
This is particularly important if you need to take antibiotics or medicines for epilepsy.
How to take NORIDAY
How to take it
Swallow one NORIDAY tablet with a glass of water at approximately the same time each day.
Follow the instructions below carefully to ensure birth control reliability.
To begin NORIDAY 28 Day, take your first tablet on the first day of your next period, that is, the day your bleeding begins.
Take your first tablet from the top row of the strip. Take the tablet which corresponds to the appropriate day of the week.
For example, if your first day of bleeding is on TUESDAY, you should take the tablet marked "TUE" from the top row.
Continue to take one tablet every day, following the arrows around the strip, until you finish all 28 tablets.
When you have finished your first strip of tablets start the next strip the following day by taking a white tablet from the
top row that matches the day of the week..
Repeat this sequence of tablet taking for as long as birth control is required. Continue taking the tablets whether you have
a period or not.
During the first two weeks of the course only, it is important to use an additional non-hormonal birth control method to provide
added protection (such as condoms or a diaphragm with contraceptive gel, but not the rhythm or temperature methods).
Make sure you always have a new strip of tablets available so that you can continue to take the tablets without interruption.
If you are switching to NORIDAY 28 Day from another 21 or 28 Day oral contraceptive, please see your doctor or pharmacist
If you suffer from a stomach upset which results in vomiting or diarrhoea, the effectiveness of NORIDAY will be reduced.
During any period of vomiting or diarrhoea, continue taking NORIDAY tablets. Also use a non-hormonal method of contraception
(such as condoms or a diaphragm with contraceptive gel, but not the rhythm or temperature methods) until your next period
When to take it
Take your tablet at approximately the same hour each day.
Taking your tablet at the same time each day will also help you remember when to take the tablets.
If you forget to take a tablet
If you forget to take NORIDAY it may not work as well in protecting you from becoming pregnant.
Do not try to make up for missed doses by taking more than one tablet at a time.
If you miss a tablet:
If you are less than 3 hours late in taking your tablet, you should take that tablet at once and then take the next one at
the usual time.
If you are more than 3 hours late in taking your tablet, still take the tablet, but an additional, non-hormonal method of
contraception must also be used until your next period occurs (such as condoms or a diaphragm with contraceptive gel, but
not the rhythm or temperature methods).
If you miss more than two tablets:
Stop taking NORIDAY immediately and use a non-hormonal method of birth control (such as condoms or a diaphragm with contraceptive
gel, but not the rhythm or temperature methods).
Continue this until your period has occurred or until your doctor has confirmed that you are not pregnant.
When you begin taking NORIDAY again, start the tablets from a new strip and follow the instructions as if starting NORIDAY
therapy for the first time.
During the first 2 weeks of this first course only, it is important to use an additional, non-hormonal method of contraception
(such as condoms or a diaphragm with contraceptive gel, but not the rhythm or temperature methods).
If your doctor has told you to take NORIDAY differently, or you are unclear about the above directions, discuss this with
him or her.
If you have trouble remembering to take your tablets, ask your pharmacist for some hints.
If you miss a period
If you have taken all the tablets correctly, you should not be concerned if you have missed a period. Continue to take your
tablets as usual.
However, if you have missed two periods, you should stop taking NORIDAY immediately and use a non-hormonal method of birth
control (such as condoms or a diaphragm with contraceptive gel, but not the rhythm or temperature methods).
Continue this until your doctor has confirmed that you are not pregnant.
If you have missed taking one or more tablets or have not taken them correctly, and have not had a period within 6 weeks of
your last period, you should stop taking the tablets immediately and use another non-hormonal method of birth control (such
as condoms or a diaphragm with contraceptive gel, but not the rhythm or temperature methods).
Continue this until your doctor has confirmed that you are not pregnant.
If you take too much (overdose)
Immediately telephone your doctor or pharmacist or the Poisons Information Centre (telephone 13 11 26) for advice, or go to
Accident and Emergency at your nearest hospital if you think you or anyone else may have taken too much NORIDAY. Do this
even if there are no signs of discomfort or poisoning.
Serious ill effects have not been reported in young children who have taken large doses of birth control pills.
Overdosage may cause nausea. This may be followed by vaginal bleeding in some women.
While you are taking NORIDAY
Things you must do
Tell all doctors, dentists and pharmacists who are treating you that you are taking NORIDAY.
Tell the hospital doctor that you are taking NORIDAY birth control pills if you need to have an operation, or go to hospital
in an emergency.
If you are about to be started on any new medicine, tell your doctor or dentist and your pharmacist that you are taking NORIDAY.
If you become pregnant while taking NORIDAY, see your doctor immediately.
Visit your doctor regularly for check-ups, including a Pap smear.
A Pap smear can detect any abnormal cells from the cervix, which may develop into cancer. Cervical cancer has been reported
to occur more frequently in women who use oral contraceptives.
Your doctor will advise you of the type and frequency of any tests required.
Perform regular, breast self-examination
Examining your breasts for lumps or any changes in size or shape can help you find a breast cancer early. Breast cancer has
been found more frequently in women who use oral contraceptives. It is not known whether this increase is caused by the use
of oral contraceptives, or if it is due to the fact that users were examined more often, and therefore the breast cancer was
If you are unsure, ask your doctor about breast self-examination.
If you are worried about contracting a sexually transmitted disease (STD) use a barrier contraceptive method.
NORIDAY does not protect against the transmission of STDs such as HIV-AIDS, chlamydia, genital herpes and warts, gonorrhoea,
hepatitis B or human papilloma virus. To protect against STDs ask your partner to wear a condom when having sexual intercourse
Tell your doctor if you feel depressed, think you are retaining water, experience headaches or experience persistent or recurrent
Your doctor will make an assessment of your condition and advise whether or not you should continue to take NORIDAY.
You may take NORIDAY if you are breastfeeding.
NORIDAY appears to have no effect on milk production or the nursing child.
Things you must not do
Do not smoke while you are taking oral contraceptives.
Cigarette smoking increases the risk of blood clotting and damage to the heart and blood vessels from birth control pills.
The risk increases with age and with heavy smoking (15 or more cigarettes per day) and is quite marked in women over 35 years
Do not stop taking your tablets if a full monthly period or slight spotting starts before all tablets have been taken.
Slight spotting during tablet taking is normally of no significance.
See your doctor if bleeding persists, or if heavier bleeding occurs.
Do not take NORIDAY past the expiry date shown on the label.
If you take the tablets after the expiry date has passed, they may not work as well.
Things to be careful of
Slight breast tenderness or a feeling of sickness may occur in the first few months of use. This usually improves or stops
with continued use.
If vaginal irritation or discharge occurs, it may be an indication of yeast infection for which treatment is available from
Women who take NORIDAY may find a change in the pattern of their period. Changes may occur to the amount of flow as well
as the duration of the period. A change in length of your menstrual cycle may also occur.
See your doctor if such bleeding persists, or if heavier bleeding occurs.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking NORIDAY.
All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment
if you get some of the side effects.
Ask your doctor or pharmacist to answer any questions you may have.
Tell your doctor if you notice any of the following and they worry you:
change in menstrual flow
absence of periods
changes in cervical secretions
change in vaginal secretions
breast changes (tenderness, enlargement and secretion)
gastric or stomach discomforts including nausea and vomiting
change in weight
retention of fluids
dark discolouration of the skin
blotchy discolouration on the face or arms or legs (which may persist after the tablets have been stopped)
rash (with or without itching)
excessive hair growth
Since the effects of long term use of "progestogen-only" pills are not known, women should be aware of the serious side effects
which have occurred with other oral contraceptives known as "Combined Oral Contraceptives". The "Combined Oral Contraceptives"
contain oestrogen and progestogen hormones.
The most serious known side effect with Combined Oral Contraceptive use is abnormal blood clotting which may have serious
consequences. Deaths have occurred in some women as a result of blood clots carried by the blood stream causing obstruction
of blood vessels in the lungs or in the brain. The risk of developing blood clotting disorders and other blood vessel diseases
in oral contraceptive users increases with age from 30 years onwards. Cigarette smoking also increases the risk. These problems
may persist after a woman has stopped taking the birth control pill.
The use of a Combined Oral Contraceptive can increase the risk of a woman having a heart attack. Other risk factors for a
heart attack include cigarette smoking; high blood pressure; high cholesterol; obesity; diabetes; a history of pre-eclamptic
toxaemia in pregnancy and age over 40 years.
Tell your doctor immediately or go to Accident and Emergency at your nearest hospital if you notice any of the following:
unexplained or persistent pains in the head, chest, stomach or legs
gradual or sudden, partial or complete loss of vision
double vision, or symptoms of severe vision impairment
eye protrusion, swelling of the eye or eye lesions
migraine headaches for the first time
more frequent or severe migraines if you already suffer from them
jaundice or a yellowing of the skin or eyes, often with fever, fatigue, loss of appetite, dark coloured urine, nausea and
vomiting. Taking oral contraceptives may be associated with liver disease, including liver cancer
rise in blood pressure
swelling of the face, lips, tongue or other parts of the body, shortness of breath, wheezing or trouble breathing.
Rarer side effects associated with the use of NORIDAY and combined oral contraceptives are not listed here. You may wish
to discuss these, or any of the side effects listed above, with your doctor if you are concerned.
Side effects not previously reported with NORIDAY may also occur.
If you notice anything unusual while you are taking NORIDAY, see your doctor.
Do not be alarmed by this list of possible side effects.
You may not experience any of them.
After stopping NORIDAY
Delays in becoming pregnant may occur after NORIDAY therapy is stopped. This is more likely to occur in women whose periods
were irregular before using birth control pills.
See your doctor if you continue to experience difficulties in falling pregnant.
After taking NORIDAY
Keep your tablets in a safe place away from the sight and reach of children.
A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.
Keep your NORIDAY tablets in a dry place, at a temperature below 25 degrees C.
Do not keep your tablets in the refrigerator.
Do not store NORIDAY or any other medicine in the bathroom or near a sink.
Do not leave it in the car on hot days or on window sills.
Heat and dampness can destroy some medicines.
If your doctor tells you to stop taking NORIDAY or if the tablets have passed their expiry date, ask your pharmacist what
to do with any that are left over.
