Common use

Tenormin is a beta-adrenergic blocking agent. Its role is to block the effects of adrenergic drugs, such as adrenaline or epinephrine, on nerves of the sympathetic nervous system. Tenormin reduces the heart rate and is used in the treatment of abnormally rapid heart rhythms, arterial hypertension, angina, acute myocardial infarction, tachycardia (different types), ventricular fibrillation, and others.

Dosage and direction

Take Tenormin before meals or at bedtime. Your dose depends on your condition and should be administered by your doctor. Take the medication exactly as prescribed. Do not change the dose, and do not stop treatment suddenly, even if you feel better, as hypertension often has no symptoms. Avoid drinking alcohol. Let your surgeon know if you are taking Tenormin if you plan to have surgery.

Precautions

Do not take Tenormin if it was not prescribed to you. Tenormin should be taken with a glass of water once a day at the same time. Do not stop taking the medication suddenly as it may worsen your condition. Continue to take the medication even if you feel fine, as hypertension and heart diseases may be lifelong illnesses. Inform your surgeon if you are taking Tenormin if you need to have surgery.

Contraindications

Hypersensitivity, sick sinus syndrome, sinus bradycardia (rate slower than 50 per minute), atrioventricular block (degree II and III), arterial hypotension, acute or chronic heart failure, peripheral blood flow disorders, breastfeeding. Cautiousness should be exercised in patients with diabetes, hypokalemia, pulmonary emphysema, asthma, liver and kidney diseases, pregnancy, and with other conditions.

Possible side effects

Side effects are rare and transient if they occur. They may include weakness, fatigue, dizziness, headache, depression, dreaming, insomnia, memory loss, abdominal cramps, diarrhea, constipation, nausea, fever, impotence, lightheadedness, slow heart rate, low blood pressure, numbness, tingling, cold extremities, sore throat, and also allergy.

Drug interaction

Tenormin can worsen conditions of patients with asthma, chronic bronchitis, or emphysema. In patients with existing slow heart rates and heart blocks, Tenormin can slow heart rates considerably. Tenormin reduces the force of heart muscle contraction and worsens the conditions of patients with heart failure. Non-steroidal anti-inflammatory drugs, estrogens, sympathomimetics, and xanthines weaken the hypotensive effect of Tenormin.
