1. What Telmisartan is and what it is
used for
Telmisartan belongs to a class of medicines known as
angiotensin II receptor antagonists. Angiotensin II is a
substance produced in your body which causes your
blood vessels to narrow which increases your blood
pressure. Telmisartan blocks the effect of angiotensin
II so that the blood vessels relax, and your blood
pressure is lowered.
Telmisartan is used to treat essential hypertension
(high blood pressure) in adults. ‘Essential’ means that
the high blood pressure is not caused by any other
If high blood pressure is not treated it can damage
blood vessels in some organs, which could possibly
lead to heart attack, heart or kidney failure, stroke,
or blindness. There are usually no symptoms of high
blood pressure before damage occurs. Thus it is
important to regularly measure blood pressure to
verify if it is within the normal range
Telmisartan is also used to reduce the risk of heart
attack or stroke in adults who are at risk because they
have a reduced or blocked blood supply to the heart
or legs, have had a stroke in the past or already have
organ damage caused by diabetes. Your doctor can
tell you if you are at high risk for such events.

2. What you need to know before you
take Telmisartan
Do not take Telmisartan

• if you are allergic to telmisartan or any of the other
ingredients of this medicine (listed in section 6)
• if you are more than 3 months pregnant (it is also
better to avoid Telmisartan in early pregnancy –
see pregnancy section)
• if you have severe liver problems such as
cholestasis or biliary obstruction (problems with
the drainage of the bile from the liver and gall
bladder) or any other severe liver disease.
• if you have diabetes mellitus or impaired kidney
function and you are treated with a blood pressure
lowering medicine containing aliskiren.
If any of the above applies to you, tell your doctor or
pharmacist before taking Telmisartan.

Warnings and precautions

Talk to your doctor if you are suffering or have ever
suffered from any of the following conditions or
• if you have kidney disease or have had a kidney
• if you have narrowing of the blood vessels to one
or both kidneys (renal artery stenosis)
• if you have any other liver disease
• if you suffer from heart trouble
• if you have low blood pressure (hypotension), likely
to occur if you have an excessive loss of body water
(dehydration), have low salt levels because you are
taking ‘water tablets’ or are on a low-salt diet or you
have diarrhoea or vomiting
• if you have water and salt retention in the body
along with imbalance of various blood minerals
(raised aldosterone levels)
• if you have high elevated potassium levels in
your blood
• if you have diabetes
Talk to your doctor or pharmacist before
taking Telmisartan:
• if you are taking digoxin
• if you are taking any of the following medicines
used to treat high blood pressure:
* an ACE-inhibitor (for example enalapril, lisinopril,
ramipril), in particular if you have diabetes-related
kidney problems.
* aliskiren
Your doctor may check your kidney function, blood
pressure, and the amount of electrolytes
(e.g. potassium) in your blood at regular intervals.

You must tell your doctor if you think that you are
(or might become) pregnant. Telmisartan 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

The use of Telmisartan in children and adolescents up
to the age of 18 years is not recommended.

Other medicines and Telmisartan

Tell your doctor or pharmacist if you are taking, have
recently taken or might take any other medicines.
Your doctor may need to change your dose of these
other medicines and/or take other precautions. In
some cases you may have to stop taking one of the
medicines. This applies especially to the medicines
listed below taken at the same time with Telmisartan:
• Lithium (to treat some types of depression)
• Medicines that may increase blood potassium
levels such as salt substitutes containing potassium,
potassium-sparing diuretics (certain ‘water tablets’),
ACE inhibitors, angiotensin II receptor antagonists,
NSAIDs (non-steroidal anti-inflammatory
medicines, e.g. aspirin or ibuprofen), heparin,
immunosuppressives (e.g. ciclosporin or
tacrolimus), and the antibiotic trimethoprim.
• ‘Water tablets’ (diuretics) e.g. furosemide,
hydrochlorothiazide, amiloride; especially if taken
in high doses together with Telmisartan may lead
to excessive loss of body water and low blood
pressure (hypotension).
• As with other blood pressure lowering medicines, the
effect of Telmisartan may be reduced when you take
NSAIDs (non-steroidal anti-inflammatory medicines,
e.g. aspirin or ibuprofen) or corticosteroids
• Other medicines to treat high blood pressure,
strong pain killers, barbiturates (for epilepsy),
baclofen (used to treat cerebral palsy and multiple
sclerosis), amifostine (used to prevent fever and
infections in patients receiving chemotherapy or
radiotherapy) or tablets for depression
• If you are taking an ACE‑inhibitor or aliskiren
(see also information under the headings
“Do not take Telmisartan” and “Warnings and
• Digoxin
Telmisartan may increase the blood pressure
lowering effect of other medicines used to treat high
blood pressure.

Telmisartan with alcohol

Telmisartan may increase the blood pressure
lowering effect if taken with alcohol, which may
make you feel dizzy or lightheaded and faint,
especially when standing after you have been sitting
or lying down.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may
be pregnant or are planning to have a baby, ask your
doctor or pharmacist for advice before taking this
You must tell your doctor if you think you are (or
might become) pregnant. Your doctor will normally
advise you to stop taking telmisartan before you
become pregnant or as soon as you know you
are pregnant and will advise you to take another
medicine. Telmisartan is not recommended in early
pregnancy, and must not be taken when more
than 3 months pregnant, as it may cause serious
harm to your baby if taken after the third month of
Tell your doctor if you are breast-feeding or about to
start breast-feeding. Telmisartan is not recommended
for mothers who are breast-feeding, and your doctor
may choose another treatment for you if you wish to
breast-feed, especially if your baby is new born, or
was born prematurely.

Driving and using machines

Some people feel dizzy or tired when they are treated
for high blood pressure. If you feel dizzy or tired, do
not drive or operate machinery.

3. How to take Telmisartan
Always take this medicine exactly as your doctor or
pharmacist has told you. Check with your doctor or
pharmacist if you are not sure.
The recommended dose of Telmisartan will depend
on what you are taking this medicine for. You should
take your dose once a day and at the same time
each day.
For the treatment of high blood pressure, the
recommended dose is 40 mg once a day to control
high blood pressure over the 24 hour period.
However, sometimes your doctor may recommend
a lower dose of 20 mg or a higher dose of 80 mg.
20 mg may be a high enough dose for some patients.
Telmisartan may also be used with diuretics (‘water
tablets’) such as hydrochlorothiazide which has been
shown to have an additive blood pressure lowering
effect with telmisartan.

See also information under the heading “Do not take

To reduce the risk of a heart attack or stroke the
recommended dose is 80 mg daily. At the beginning
of treatment your blood pressure should be
frequently monitored.

If you are black; as with all other angiotensin II
receptor antagonists, Telmisartan may be less effective
in lowering the blood pressure in black patients.

If you have the impression that the effect of
Telmisartan is too strong or too weak, talk to your
doctor or pharmacist.

Your medicine is available in 3 strengths: 20 mg,
40 mg and 80 mg

rash and often including blisters (eczema), redness
of skin, hives (urticaria)

In a long-term study involving more than
20,000 patients, more patients treated with
telmisartan experienced sepsis compared with
patients who received no telmisartan. The event may
have happened by chance or could be related to a
mechanism currently not known.
Most cases of abnormal liver function and liver
disorder from post-marketing experience with
telmisartan occurred in Japanese patients. Japanese
patients are more likely to experience this side effect.

Cases of progressive scarring of lung tissue have
been reported during intake of telmisartan. However,
it is not known whether telmisartan was the cause.
