1. What Seles Beta is and what it is used for
Seles Beta contains an active substance called atenolol.
Atenolol belongs to a group of medicines known as beta-blockers, which reduce heart rate and
blood pressure.
Seles Beta is indicated for the treatment:
- of high blood pressure (arterial hypertension), including that of renal origin
- of chest pain due to heart problems (angina pectoris)
2. What you should know before taking Seles Beta
Do not take Seles Beta
- If you are allergic to atenolol or to any of the other ingredients of this medicine (listed in section 6).
- If you have a very slow heartbeat (bradycardia).
- If you have a severe heart problem known as cardiogenic shock, which occurs when your heart does not pump enough blood throughout the body.
- If you suffer from very low blood pressure (hypotension).
- If your doctor has diagnosed you with abnormally high levels of acid in the blood (metabolic acidosis).
- If you suffer from severe peripheral arterial circulation disorders or have a severe form of a rare disease characterized by brief episodes of narrowing of the arteries, the blood vessels carrying blood from the heart to the rest of the body (Raynaud's syndrome).
- If you have a heart rhythm disorder called "sinoatrial disease" or "second- or third-degree atrioventricular block".
- If you have an untreated tumour of the adrenal gland called "pheochromocytoma".
- If your heart function is inadequate and not controlled by appropriate therapy (overt uncontrolled heart failure).
- If you are being treated with intravenous medicines called calcium antagonists, for example verapamil (used to treat high blood pressure) or diltiazem (used to treat high blood pressure, angina pectoris, and other heart conditions), or medicines used to normalize heart rhythm, such as disopyramide.
- If you are taking medicines used to treat depression (MAO inhibitors, except MAO-B inhibitors).
- If you suffer from severe asthma or severe chronic obstructive pulmonary disease.
- If you are breastfeeding.
Warnings and precautions
Talk to your doctor or pharmacist before taking Seles Beta:
- If you suffer from heart failure.
- If you have a heart condition called Prinzmetal's angina, because Seles Beta may increase the number and duration of angina attacks.
- If you have peripheral arterial circulation disorders (see also section 2 “Do not take Seles Beta”), even if mild, because Seles Beta may worsen these conditions.
- If you have a heart rhythm disorder called first-degree atrioventricular block, because Seles Beta may worsen this condition.
- If you suffer from hypoglycaemia or diabetes; this medicine may mask the symptoms indicating that blood sugar levels (glycaemia) have dropped too low (hypoglycaemia), such as increased heart rate, palpitations, and excessive sweating. Atenolol may also increase the risk of severe hypoglycaemia when used with certain types of antidiabetic medicines called sulfonylureas (e.g. gliquidone, gliclazide, glibenclamide, glipizide, glimepiride or tolbutamide).
- If you have thyroid problems (thyrotoxicosis). The medicine may mask symptoms of thyrotoxicosis such as rapid heartbeat, tremor, or excessive sweating.
- If you have excessive reduction in heart rate. In such cases, your doctor may consider reducing the dose of the medicine.
- If you have a history of severe allergic reactions (e.g. anaphylaxis); this medicine may worsen such allergic reactions and reduce the response to adrenaline therapy. Seles Beta may also cause angioedema and urticaria.
- If you suffer from sudden spasms of the airways (bronchospasm), such as asthma. In such cases, your doctor may adjust the dosage of the medicine.
- If you are being treated for a tumour called pheochromocytoma; in this case, blood pressure must be closely monitored during treatment.
- If you are using ophthalmic beta-blockers, as the effects of Seles Beta may be enhanced.
- If you develop symptoms such as skin rash and joint pain, which could indicate a disease called "systemic lupus erythematosus", your doctor may decide to discontinue treatment (see section 4 “Undesirable effects”).
- If you suffer from kidney problems.
- If you are pregnant, planning to become pregnant, or breastfeeding (see section “Pregnancy and Breastfeeding” and section “Do not take Seles Beta”).
- If you have a predisposition to a skin condition called psoriasis.
If you are undergoing surgery, inform your doctor or healthcare staff that you are taking Seles Beta.
It is important not to stop treatment with Seles Beta abruptly, especially in patients with ischaemic heart disease. If you need to stop or discontinue treatment with Seles Beta after prolonged use, the dose should always be reduced gradually by tapering, as sudden discontinuation may lead to reduced oxygenated blood supply to a more or less extensive area of the heart (myocardial ischaemia), resulting in worsening of angina pectoris (a heart condition characterized by chest pain), or myocardial infarction, or may cause worsening of hypertension.
Anti-doping tests
For athletes: the use of this medicine without therapeutic need constitutes doping and may result in a positive anti-doping test.
Children and adolescents
The use of Seles Beta is not recommended in individuals under 18 years of age.

3. How to take Seles Beta
Take this medicine exactly as directed by your doctor or pharmacist. If you have
any doubts, consult your doctor or pharmacist.
Your doctor will tell you how many tablets to take each day and when, depending on your condition. The recommended starting
dose, especially in elderly patients, is the lowest possible dose in order to promptly identify
the onset of symptoms of heart failure (the heart's inability to supply adequate blood flow to meet the body's needs),
bradycardia (reduction in heart rate below 60 beats per minute), and bronchial symptoms.
Swallow the tablets whole with a glass of water, away from meals.
Adults
Treatment of high blood pressure (arterial hypertension), including that of renal origin
The recommended dose is half a tablet (50 mg) or one tablet (100 mg) daily.
Your doctor will prescribe the dose most suitable for your hypertension.
Usually, improvement becomes evident after one or two weeks of treatment.
Prevention of chest pain (angina pectoris)
The recommended dose is one tablet (100 mg) daily.
Elderly patients
If you are elderly (aged over 65 years), your doctor may decide to prescribe Seles Beta at lower doses,
especially if you have kidney problems.
Use in children and adolescents
Use of Seles Beta is not recommended in individuals under 18 years of age.
Patients with reduced kidney function (renal insufficiency)
If you have severe kidney problems, your doctor will prescribe the appropriate dose of Seles Beta based on the severity
of your renal insufficiency.
If you are undergoing haemodialysis, the recommended dose is half a tablet (50 mg) of Seles Beta after each dialysis session,
administered in hospital so that immediate intervention is possible should blood pressure drop excessively.
If you take more Seles Beta than you should
If you take more Seles Beta than prescribed, contact your doctor immediately or go to the nearest hospital emergency department.
Take the medicine pack with you so that the doctor knows what you have taken.
The following symptoms may occur: slow heartbeat, low blood pressure, problems with the heart's pumping function (acute heart failure) and breathing difficulties, as well as narrowing of the lower airways (bronchi) causing breathing difficulty (bronchospasm).
If you forget to take Seles Beta
If you forget to take a dose of Seles Beta, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose. Do not take a double dose to make up for the forgotten one.
If you stop taking Seles Beta
Do not stop taking Seles Beta without talking to your doctor.
It is necessary to stop treatment gradually.
If you have any questions about the use of this medicine, consult your doctor or pharmacist.
