ontents of the pack and other information
1. What Telmisartan is and what it is
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
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 –

• 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.

NSAIDs (non-steroidal anti-inflammatory
medicines, e.g. aspirin or ibuprofen), heparin,
immunosuppressives (e.g. ciclosporin or

• ‘Water tablets’ (diuretics) e.g. furosemide,
hydrochlorothiazide, amiloride; especially if taken
in high doses together with Telmisartan may lead

• 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

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.

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.
