6. Contents of the pack and other information
Tenif contains the active substances atenolol and nifedipine. Each of these
works in a different way.
- Atenolol belongs to a group of medicines called beta-blockers. It works by
making your heart beat more slowly and with less force.
This helps to prevent chest pain.
- Nifedipine belongs to a group of medicines 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).
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
- If you are allergic (hypersensitive) to other dihydropyridines such as
amlodipine or felodipine.
- If you have any of the following heart problems:
- heart failure which is not under control (this usually makes you
breathless and causes your ankles or legs to swell)
- second- or third-degree heart block (a condition which may be treated
with a pacemaker)
- a very slow or very uneven heart beat, very low blood pressure or very
poor circulation
- a heart attack within the last month
- a heart condition called sick sinus syndrome, or unstable angina, or
aortic stenosis
- a condition where the heart is unable to supply enough blood to the
body (cardiogenic shock).
- within one month of a heart condition (e.g. chest pain, angina, heart
- 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
- 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.
