1.  hat Tenif is and what it is used for
W
Tenif contains the active substances atenolol and
nifedipine. Each of these works in a different way.
•  tenolol belongs to a group of medicines
A
called beta-blockers. It works by making your
heart beat more slowly and with less force.
This helps to prevent chest pain.
•  ifedipine belongs to a group of medicines
N
called dihydropyridines. Dihydropyridines are
a type of calcium channel blocker. They work
by making your blood vessels widen. This
helps to prevent chest pain and lowers your
blood pressure.
Tenif is used to treat high blood pressure
(hypertension) or to prevent chest pain (angina).
2.  hat you need to know before you take
W
Tenif
Do not take Tenif:
• If you are allergic to atenolol, nifedipine, or any
of the other ingredients of this medicine (listed
in section 6).
• If you are having an angina attack (sudden
chest pain). Tenif cannot treat an angina
attack, but it can help you get fewer attacks if
you take it regularly.
• If you are allergic (hypersensitive) to other
dihydropyridines such as amlodipine or
felodipine.
• If you have any of the following heart problems:
-- ­ eart failure which is not under control (this

your ankles or legs to swell)

(a condition which may be treated with
a pacemaker)
-- ­ very slow or very uneven heart beat, very
a

low blood pressure or very poor circulation
-- ­ heart attack within the last month
a

-- ­ heart condition called sick sinus
a

syndrome, or unstable angina, or aortic
stenosis
-- ­ condition where the heart is unable
a

to supply enough blood to the body
(cardiogenic shock).
-- ­ ithin one month of a heart condition (e.g.

w
chest pain, angina, heart attack).
• If you have problems with your kidneys.
• If you have a tumour called phaeochromocytoma
that is not being treated. This is usually near
your kidney and can cause high blood pressure.
• If your doctor has told you that you have
higher than normal levels of acid in your blood
(metabolic acidosis).
• If you have not been eating much recently.
• If you are taking a medicine called rifampicin.
• If you are taking a medicine that is a certain
type of calcium channel blocker such as
verapamil or diltiazem.
• If you are a woman at an age where you
could get pregnant, or you are pregnant or
breast‑feeding (see the section on “Pregnancy,
breast‑feeding and fertility” below).
• If you have severe liver failure.
If you are not sure if any of the above apply to
you, talk to your doctor or pharmacist before
taking Tenif.

Prinzmetal’s angina.
• If you have poor blood circulation or controlled
heart failure.

which may be treated by a pacemaker).
• If you have liver problems. Your doctor may
need to do tests during your treatment with
Tenif to check how well your liver is working.
• If you have diabetes. Your medicine may
change how you respond to having low blood
sugar. You may feel your heart beating faster.
Your medicine may hide the symptoms of low
blood sugar.
• If you suffer from treated phaeochromocytoma
(high blood pressure due to a tumour near your
kidney). Your blood pressure will be monitored
closely by your doctor.
• If you have thyrotoxicosis (a condition caused
by an overactive thyroid gland). Your medicine
may hide the symptoms of thyrotoxicosis.
• If you are to be given an anaesthetic agent.
• If you are giving a urine sample for a doping
test. Tenif may cause a positive result.
• If you are a man whose female partner is
having IVF (in-vitro fertilisation treatment). This
is because Tenif can affect your sperm.
If you give a urine sample, it is important to tell your
doctor that you are taking Tenif. This is because
Tenif may interfere with the urine test results.
