Contents of the pack and further information

1. What is Atenolol Sandoz and what is it used for

Atenolol Sandoz contains a medicine called atenolol. This belongs to a group of medicines called beta-blockers.

Atenolol Sandoz is used for:

  • treatment of high blood pressure (hypertension),
  • helping to prevent chest pain (angina pectoris),
  • ensuring regular heartbeats,
  • protecting the heart during and after a heart attack.

2. What you need to know before taking Atenolol Sandoz

Do not take Atenolol Sandoz:

  • if you are allergic to atenolol or any of the other ingredients of this medicine (listed in section 6),
  • if you have or have had any of the following heart problems:
  • uncontrolled heart failure (this usually causes shortness of breath and swelling of the ankles),
  • second or third degree heart block (a condition that can be treated with a pacemaker),
  • very slow or irregular heartbeats, very low blood pressure or very poor circulation (circulatory failure),
  • if you have cardiogenic shock. This means that the heart is not pumping blood around the body well enough. The signs can include confusion, sweating, fast heartbeats and paleness,
  • if you have an untreated tumour of the adrenal glands called phaeochromocytoma.
  • if you have been fasting
  • if your doctor has told you that you have excessive acidity of the blood (metabolic acidosis),

Do not take Atenolol Sandoz in any of the above situations. If you are not sure, consult your doctor or pharmacist before taking this medicine.

Warnings and precautions

Talk to your doctor or pharmacist before starting to take Atenolol Sandoz if:

  • you have asthma, wheezing or other respiratory problems, or have allergic reactions, for example to insect bites. If you have ever had asthma or wheezing, do not take this medicine without talking to your doctor,
  • you have a type of chest pain called Prinzmetal's angina,
  • you have first degree heart block,
  • you have diabetes. Atenolol may change your normal response to low blood sugar (hypoglycaemia), which usually involves an increase in heart rate. You should closely monitor your blood sugar levels,
  • you have thyrotoxicosis (a condition caused by an overactive thyroid gland). Your medicine could mask the symptoms of thyrotoxicosis,
  • you have kidney problems. You may need to have regular check-ups while you are taking this medicine,
  • you have a skin problem called psoriasis,
  • you may notice that your pulse is slower while taking these tablets. This is normal, but if it worries you, tell your doctor.,
  • you are elderly,
  • you are pregnant, think you might be pregnant or are breast-feeding. See “Pregnancy and breast-feeding”,
  • you have ever had an allergic reaction to anything, for example to an insect bite,
  • if you are going to hospital for an operation, tell the anaesthetist or the medical staff that you are taking atenolol. This is because you may have a low blood pressure (hypotension) if you are given certain anaesthetics, or substances containing iodine (called “contrast media”) for X-rays, while you are taking atenolol.

If you think any of the above applies to you, or if you are not sure, consult your doctor or pharmacist before taking this medicine.

Using Atenolol Sandoz with other medicines

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including those obtained without a prescription, herbal remedies, and other health products, as it may be necessary to stop treatment or adjust the dose of one of them.

Some medicines can affect the action of others.

Tell your doctor or pharmacist if you are taking any of the following medicines:

  • clonidine (for hypertension or migraine). If you are taking clonidine and atenolol together, do not stop taking clonidine unless your doctor tells you to. If you need to stop taking clonidine, your doctor will give you detailed instructions on how to do it,
  • verapamil, diltiazem and nifedipine (for high blood pressure and chest pain),
  • disopyramide, quinidine, amiodarone and any other medicine for irregular heartbeats,
  • digoxin (for heart failure), adrenaline, also known as epinephrine (medicines that stimulate the heart),
  • ibuprofen or indomethacin (anti-inflammatory medicines for pain relief),
  • insulin or other oral medicines for diabetes,
  • ampicillin, for bacterial infections,
  • barbiturates, for sleep problems and epilepsy,
  • sulpiride and phenothiazines, for more serious mental health problems (psychosis),
  • medicines from the groups called “tricyclic antidepressants” or “MAO inhibitors”,
  • nasal decongestants or other medicines for colds or sinus blockage (including over-the-counter medicines),
  • if you are going to hospital for an operation, tell the anaesthetist or the medical staff that you are taking atenolol. This is because you may have a low blood pressure (hypotension) if you are given certain anaesthetics, or substances containing iodine (called “contrast media”) for X-rays, while you are taking atenolol.

If you think any of the above applies to you, or if you are not sure, consult your doctor or pharmacist before taking this medicine.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Pregnancy

There is not enough information on the safety of atenolol during the first month of pregnancy. Your doctor will decide whether treatment during the second and third trimester is beneficial for you.

Breast-feeding

Tell your doctor if you are being treated with atenolol during childbirth or breast-feeding, as your baby may be at risk of low blood sugar and slower heartbeats.

Women who are breast-feeding should consult their doctor before taking this medicine, as atenolol passes into breast milk.

Driving and using machines

  • It is unlikely that this medicine will affect your ability to drive or use machines.
  • However, it is better to wait and see how the medicine affects you before carrying out these activities.
  • If you feel dizzy or tired while taking this medicine, do not drive or use tools or machines.

Use in athletes

This medicine contains atenolol, which may produce a positive result in doping tests.

Atenolol Sandoz contains lactose and sodium

This medicine contains lactose. If your doctor has told you that you have an intolerance to some sugars, consult them before taking this medicine.

This medicine contains less than 23 mg of sodium (1 mmol) per tablet; this is, essentially, “sodium-free”.

3. How to take Atenolol Sandoz

Always take this medicine exactly as your doctor or pharmacist has told you. If you are not sure, check with your doctor or pharmacist.

  • Your doctor will tell you how many tablets to take each day and when to take them.
  • Read the package to remind you of the information your doctor gave you.
  • Try to take the tablets at the same time each day.
  • Swallow the tablets whole with a glass of water. The score line is only there to help you break the tablet if you have difficulty swallowing it whole.

  • After that, you will usually take between 50 mg and 100 mg daily.

Patients with severe kidney problems

If you have severe kidney problems, your doctor may prescribe a lower dose of atenolol or tell you to take it less often.

Use in children

This medicine should not be given to children.

If you take more Atenolol Sandoz than you should

In case of overdose or accidental ingestion, consult your doctor or pharmacist immediately or call the Toxicology Information Service, telephone: 91 562 04 20, indicating the medicine and the amount taken.

  • If you take more Atenolol Sandoz than you should, talk to a doctor or go to a hospital straight away.
  • Take the medicine package with you, so the doctor can identify what you have taken.
  • You may feel a slower pulse, dizziness due to low blood pressure and difficulty breathing. Also, your heart may have problems supplying blood to the rest of the body (acute heart failure).

If you forget to take Atenolol Sandoz

  • If you forget to take a dose, take it as soon as you remember.
  • However, if it is almost time for the next dose, do not take the missed dose.
  • Do not take a double dose to make up for forgotten doses.
