1. WHAT TENIF IS AND WHAT IT IS USED FOR
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).
2. WHAT YOU NEED TO KNOW BEFORE YOU TAKE 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:
- 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 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.
Warnings and precautions

- If you have poor blood circulation or controlled heart failure.

- 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.
