What Olmesartan is and what it is
Olmesartan belongs to a group of medicines
called angiotensin-II receptor antagonists.
They lower blood pressure by relaxing the
Olmesartan is used for the treatment of high
blood pressure (also known as “hypertension”)
in adults and in children and adolescents aged
6 to less than 18 years. High blood pressure
can damage blood vessels in organs such as
the heart, kidneys, brain and eyes. In some
cases this may lead to a heart attack, heart
or kidney failure, stroke or blindness. Usually
high blood pressure has no symptoms.
It is important to have your blood pressure
checked to prevent damage occurring.
High blood pressure can be controlled with
medicines such as Olmesartan tablets. Your
doctor has probably also recommended that
you make some changes in your lifestyle to
help lower your blood pressure (for example
losing weight, giving up smoking, reducing the
amount of alcohol you drink and reducing the
amount of salt in your diet). Your doctor may
also have urged you to take regular exercise,
such as walking or swimming. It is important to
follow this advice from your doctor.
What you need to know before you
Do not take Olmesartan:
if you are allergic to Olmesartan
medoxomil or any of the other ingredients
of this medicine (listed in section 6).
if you are more than 3 months pregnant.

tablets in early pregnancy – see

and eyes (jaundice) or problems with

As with any medicine which reduces blood
pressure, an excessive drop in blood pressure
in patients with blood flow disturbances of the
heart or brain could lead to a heart attack or
stroke. Your doctor will therefore check your
blood pressure carefully.
You must tell your doctor if you think you are
(or might become) pregnant. Olmesartan is
not recommended in early pregnancy, and
must not be taken if you are more than
3 months pregnant, as it may cause serious
harm to your baby if used at that stage (see
As with other similar drugs the blood pressure
lowering effect of Olmesartan is somewhat
less in black patients.
If you are 65 years or over and your doctor
decides to increase your dose of olmesartan
medoxomil to 40 mg daily, then you need to
have your blood pressure regularly checked
by your doctor to make sure that your blood
pressure does not become too low.
Children and adolescents

in children and adolescents. For more
information, talk to your doctor. Olmesartan
medoxomil is not recommended for children

before you become pregnant or as soon as
you know you are pregnant and will advise
you to take another medicine instead of

in early pregnancy, and must not be taken
when more than 3 months pregnant, as it may
cause serious harm to your baby if used after
the third month of pregnancy.

about to start breast-feeding. Olmesartan is
not recommended for mothers who are breastfeeding, and your doctor may choose another
treatment for you if you wish to breast-feed,
