Infections (STIs), such as chlamydia, genital herpes,
genital warts, gonorrhoea, hepatitis B, human
papilloma virus and syphilis
• If you are going to have surgery, tell your doctor
beforehand that you are taking YAZ. The risk of
having blood clots is temporarily increased as a result
of major surgery, any surgery to the legs or pelvis,
neurosurgery or major trauma.
• In women at risk of prolonged immobilisation
(including major surgery, any surgery to the legs or
pelvis, neurosurgery, or major trauma), your doctor
may tell you to stop taking (in the case of elective
surgery at least four weeks in advance) and not
resume until two weeks after complete
remobilisation. Another method of contraception
should be used to avoid unintentional pregnancy. Your
doctor may prescribe other treatment (e.g. treatment
for blood clots) if YAZ has not been discontinued in
advance.
• Tell your doctor if you plan to air travel for greater
than 4 hours. There may be an increased risk of blood
clots due to lack of movement, particularly in women
with other risk factors.
• Have regular check-ups with your doctor. When you
are taking the Pill, your doctor will tell you to return
for regular check-ups, including getting a Cervical
Screening Test. Your doctor will advise how often you
need a Cervical Screening Test. A Cervical Screening
Test can detect abnormal cells lining the cervix.
Sometimes abnormal cells can progress to cancer.
• Tell your doctor if you develop high blood pressure
while taking YAZ – you may be told to stop taking it.
• If you are about to start on any new medicine,
remind your doctor and pharmacist that you are
taking YAZ.

Things you should not do
• Do not take YAZ to treat any other conditions, unless
your doctor tells you to.
• Do not give your medicine to anyone else.
• Do not stop taking your medicine or change
the dosage without checking with your doctor. You
may become pregnant if you are not using any other
contraceptive and you stop taking YAZ, or do not take
a tablet every day.
Bleeding and Missed Periods
When taking these tablets for the first few months, you
can have irregular vaginal bleeding (spotting or
breakthrough bleeding) between your periods. You may
need to use sanitary products, but continue to take your
tablets as normal. Irregular vaginal bleeding usually stops
once your body has adjusted to the Pill, usually after about
3 months.
If you have missed a period, but you have taken all your
tablets, it is very unlikely that you are pregnant, as long
as:
• you have taken the light pink active tablets at the right
time
• you have not been taking medicine(s) that may interfere
with YAZ
• you have not vomited or had severe diarrhoea during
this cycle.
If this is so, continue to take YAZ as usual. If you have any
concerns consult your doctor or pharmacist.
If you miss your period twice in a row, you may be
pregnant even if you have taken the Pill correctly. Stop
taking YAZ and seek advice from your doctor. You must
use a non-hormonal method of contraception, (such as
condoms or a diaphragm) until your doctor rules out
pregnancy.
If you choose to delay your period while taking YAZ, your
regular bleeding is not expected to occur during the
