1. What is Beto 50 ZK and what is it used for

Metoprolol succinate (selective beta-adrenergic blocker), the active substance of Beto 50 ZK, blocks certain beta-adrenergic receptors in the body, mainly located in the heart.
Beto 50 ZK is used:

• to treat high blood pressure,
• to treat chest pain,
• to treat heart rhythm disorders, including accelerated heart rate,
• for the prevention of heart attackafter an acute phase,
• in case of unpleasant sensation of irregularand (or) strong heartbeat,
• to prevent migraine,
• to treat heart failure.

In children and adolescents from 6 to 18 years old

• to treat high blood pressure(hypertension).

2. Important information before taking Beto 50 ZK

When not to take Beto 50 ZK

• monoamine oxidase inhibitors (MAOIs) - medicines used to treat depression;
• verapamil and diltiazem (medicines used to lower blood pressure);
• antiarrhythmic drugs, such as disopyramide (medicines used to treat irregular heartbeat).

In patients with chronic heart failure, metoprolol should not be used if:

• they have unstable, uncontrolled heart failure (which may manifest as fluid accumulation in the lungs, poor circulation, or low blood pressure).
• they are constantly or periodically receiving drugs that increase the strength of heart contractions.
• they have a slow heart rate (less than 68 beats/min at rest before treatment).
• their systolic blood pressure is consistently less than 100 mmHg.

Warnings and precautions

Before starting to take Beto 50 ZK, you should discuss it with your doctor or pharmacist if:

• you have asthma, bronchitis, or lung function disorders;
• you have heart function disorders (e.g., slow heart rate) or circulatory disorders (taking Beto 50 ZK may worsen their course);
• you have diabetes;
• you have thyroid function disorders;
• you have severe liver disease;
• you have had a severe allergic reaction to any allergen;
• you have a rare form of chest pain, so-called Prinzmetal's angina;
• you need to undergo surgery that requires general anesthesia. You should inform the anesthesiologist about taking Beto 50 ZK.
• you have a tumor of the adrenal gland that secretes hormones (pheochromocytoma): in such a case, it is necessary to use a medicine that blocks alpha-adrenergic receptors beforehand and at the same time.
• you have psoriasis.

Taking metoprolol may cause positive results in anti-doping tests.

Children and adolescents

Experience with the treatment of children under 6 years old is limited.
Beto 50 ZK should not be used in children under 6 years old.

Beto 50 ZK and other medicines

You should tell your doctor or pharmacist about all medicines you are taking now or have taken recently, as well as about medicines you plan to take.
Beto 50 ZK interacts with many other medicines.

• Medicines used to treat high blood pressure (including prazosin, clonidine, hydralazine, guanethidine, betanidine, reserpine, alpha-methyldopa, and so-called calcium antagonists, e.g., verapamil, diltiazem, or nifedipine).
• Other beta-adrenergic blockers (also those contained in eye drops).
• Medicines that affect peripheral blood circulation (in fingers and toes), such as ergot alkaloids (which can be used to treat migraine).
• Medicines used to treat depression.
• Medicines used to treat other mental disorders.
• Antiretroviral medicines used to treat AIDS and some other diseases.
• Antihistamines (also available without a prescription, medicines used to treat hay fever and other allergies, colds, and other conditions).
• Medicines used to prevent malaria.
• Medicines used to treat fungal infections.
• Medicines that affect liver enzyme activity, rifampicin used to treat tuberculosis.
• Medicines used to treat heart function disorders (also angina pectoris), such as amiodarone, digoxin, nitrates, and antiarrhythmic drugs.
• Other medicines that slow down heart rate: the use of fingolimod (a medicine used in adults, children, and adolescents to treat relapsing-remitting multiple sclerosis) with beta-adrenergic blockers may enhance the heart rate-slowing effect in the first few days after starting fingolimod.
• Other medicines that lower blood pressure: the use of aldesleukin (a synthetic protein used to treat kidney cancer with metastases to other organs) with beta-adrenergic blockers may cause enhanced blood pressure-lowering effect.
• Insulin and other anti-diabetic medicines.
• Non-steroidal anti-inflammatory drugs (NSAIDs), used to treat pain and inflammation.
• Local anesthetics containing lidocaine.
• A medicine called dipyridamole, which prevents blood clots.

Beto 50 ZK with food, drink, and alcohol

Beto 50 ZK and alcoholcan mutually enhance their sedative effect. The blood alcohol concentration may reach higher values and decrease more slowly.
During treatment with Beto 50 ZK, you should avoid drinking alcohol.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, you should consult your doctor or pharmacist before taking this medicine.
Pregnancy
Beto 50 ZK can be used during pregnancy only if clearly necessary and after a careful assessment of the benefit-to-risk ratio by the doctor. There is evidence that metoprolol reduces blood flow in the placenta, which may lead to fetal development disorders. Treatment with Beto 50 ZK should be discontinued 48 to 72 hours before the expected delivery date. If this is not possible, the doctor will closely monitor the newborn for 48 to 72 hours after birth.
Breastfeeding
Beto 50 ZK passes into breast milk.
Metoprolol succinate should not be taken during breastfeeding if not absolutely necessary.
Although the occurrence of side effects is unlikely when using the recommended doses, you should closely monitor the breastfed infant for signs of drug effects (e.g., the doctor will monitor heart rate).

Driving and using machines

During treatment with Beto 50 ZK, dizzinessor fatiguemay occur. These symptoms can affect reaction speed to the extent that it impairs the ability to drive vehicles, operate machinery, and work in potentially hazardous conditions. Symptoms may occur especially when consuming alcohol, as well as when switching from one medicine to another.

Beto 50 ZK contains glucose, lactose monohydrate, and sucrose (sugar)

If you have previously been diagnosed with intolerance to some sugars, you should contact your doctor before taking Beto 50 ZK.

Use in children and adolescents
High blood pressure:
In children over 6 years old, the dose depends on body weight. The doctor will determine the dose suitable for the patient.
Usually, the initial dose of metoprolol succinate is 0.48 mg/kg body weight once a day, but not more than 47.5 mg. The dose is adjusted to the nearest tablet strength. The doctor may increase the dose to 1.9 mg/kg body weight, depending on the blood pressure response. In children and adolescents, doses above 190 mg/day have not been studied.

The duration of treatment is determined by the doctor.
If you feel that the effect of Beto 50 ZK is too strong or too weak, you should consult your doctor or pharmacist.

Treatment of overdose
The patient should be treated in a hospital, in the intensive care unit. Even patients who seem to be in good condition and have only slightly overdosed on metoprolol should be closely monitored by the doctor for at least 4 hours for signs of poisoning.

Missing a dose of Beto 50 ZK

Stopping treatment with Beto 50 ZK

Before stopping or prematurely discontinuing treatment with Beto 50 ZK, you should consult your doctor.
Beto 50 ZK should not be stopped abruptly, but the dose should be gradually reduced. Abrupt cessation of beta-adrenergic blockers may worsen the symptoms of heart failure and increase the risk of heart attack and sudden cardiac death.
