1. What ATENOLOLO ZENTIVA is and what it is used for

ATENOLOLO ZENTIVA contains atenolol.
Atenolol belongs to a group of medicines called beta-blockers, which work by slowing down the heartbeat (reducing heart rate and cardiac contractility).
ATENOLOLO ZENTIVA is indicated in adults for:

  • treating high blood pressure (arterial hypertension)
  • treating angina pectoris attacks (heart disease characterized by chest pain)
  • treating irregular heartbeat (arrhythmias)
  • helping to prevent the occurrence of another heart attack (acute myocardial infarction)

Talk to your doctor if you do not feel better or if you feel worse.

2. What you need to know before taking ATENOLOL ZENTIVA

Do not take ATENOLOL ZENTIVA

  • if you are allergic to atenolol or to any of the other ingredients of this medicine (listed in section 6)
  • if you have heart diseases, including uncontrolled heart failure not managed by adequate therapy, or heart block
  • if you have slow or irregular heartbeats, very low blood pressure, or severe circulatory disorders
  • if you have a heart condition occurring when blood is inadequately oxygenated (cardiogenic shock)
  • if your doctor has diagnosed abnormally high levels of acid in your blood (metabolic acidosis)
  • if you have a tumor called "pheochromocytoma" that is not being treated (this tumor usually develops near a kidney and may cause high blood pressure)

If you are in any of the above situations, inform your doctor.
Warnings and precautions
Talk to your doctor or pharmacist before taking ATENOLOL ZENTIVA:

  • if you have kidney problems
  • if you have thyroid problems (a gland located in the neck)
  • if you have diabetes (a condition characterized by excess sugar in the blood)
  • if you have heart or circulatory problems, even if controlled by adequate therapy
  • if you have respiratory problems or asthma
  • if you have a type of chest pain called "Prinzmetal's angina"
  • if you are pregnant, planning to become pregnant, or breastfeeding (See section “Pregnancy and Breast-feeding”)
  • if you have previously experienced allergic reactions (e.g., from insect stings)
  • if you are being treated with verapamil or diltiazem

Reduced heart rate (lower number of heartbeats per minute)
During treatment with ATENOLOL ZENTIVA, you may experience a reduced heart rate (see section 4 “Possible side effects”). This effect is normal, but if it causes concern, consult your doctor.
Diabetes or hypoglycemia (low blood sugar levels)
If you have diabetes and are taking antidiabetic medicines (medicines for treating diabetes), this medicine may increase your blood sugar levels. This usually causes an increased heart rate.
Anaesthesia
If you need to be admitted to hospital, you must inform medical staff that you are being treated with ATENOLOL ZENTIVA, and particularly inform the anaesthetist (the doctor administering anaesthesia) if you are undergoing surgery.
For athletes
Using this medicine without a therapeutic need constitutes doping and may lead to a positive result in anti-doping tests.
Children and adolescents
ATENOLOL ZENTIVA must not be given to children and adolescents under 18 years of age.
