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

Talk to your doctor or pharmacist before taking Tenif:

•    If you have asthma, wheezing or similar breathing problems, or you get allergic reactions, such as to insect stings. If you have ever had asthma or wheezing, do not take this medicine without first checking with your doctor.

•    If you have a type of chest pain (angina) called Prinzmetal’s angina.

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

•    If you have first-degree heart block (a condition 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.

If you go into hospital to have an operation, tell the anaesthetist or doctor that you are taking Tenif. This is because you can get low blood pressure (hypotension) if you are given certain anaesthetics while you are taking Tenif.

Tenif with food and drink

Do not drink grapefruit juice throughout the whole period of time you take Tenif. This is because your blood pressure may be reduced too much, which may make you feel dizzy.

•    Do not take Tenif if you are breast-feeding.
