Common Use

Tenormin is a beta-adrenergic blocking agent. It works by blocking the effects of adrenergic drugs, such as adrenaline or epinephrine, on the nerves of the sympathetic nervous system. Tenormin helps reduce the heart rate and is used to treat abnormally rapid heart rhythms, arterial hypertension, angina, acute myocardial infarction, tachycardia (various types), ventricular fibrillation, and other conditions.

Dosage and Direction

Take Tenormin before meals or at bedtime. The dosage depends on your condition and should be determined by your doctor. Follow the prescribed instructions carefully. Do not alter the dose or stop treatment abruptly, even if you feel better, as hypertension often has no symptoms. Avoid alcohol consumption. Inform your surgeon if you are taking Tenormin before any planned surgery.

Precautions

Take Tenormin with a glass of water once a day at the same time. Do not discontinue the medication suddenly, as this may worsen your condition. Continue taking the medication even if you feel fine, as hypertension and heart diseases may require lifelong treatment. Notify your surgeon if you are on Tenormin before undergoing surgery.

Contraindications

Tenormin should not be used if you have hypersensitivity, sick sinus syndrome, sinus bradycardia (heart rate slower than 50 per minute), atrioventricular block (degree II and III), arterial hypotension, acute or chronic heart failure, or peripheral blood flow disorders. It is also contraindicated during breastfeeding. Use with caution in patients with diabetes, hypopotassemia, pulmonary emphysema, asthma, liver or kidney diseases, pregnancy, and other conditions.

Possible Side Effects

Side effects are rare and usually temporary. They may include:

• Weakness and fatigue
• Dizziness and headache
• Depression, dreaming, or insomnia
• Memory loss
• Abdominal cramps, diarrhea, constipation, or nausea
• Fever, impotence, or lightheadedness
• Slow heart rate or low blood pressure
• Numbness, tingling, or cold extremities
• Sore throat or allergic reactions

Drug Interactions

Tenormin may worsen conditions in patients with asthma, chronic bronchitis, or emphysema. It can significantly slow heart rates in patients with existing slow heart rates or heart blocks. The medication reduces the force of heart muscle contraction and may aggravate heart failure. Non-steroidal anti-inflammatory drugs, estrogens, sympathomimetics, and xanthines may weaken the hypotensive effect of Tenormin.

Missed Dose

Do not take a double dose. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule.

Overdose

Symptoms of an overdose include uneven heartbeats, shortness of breath, dizziness, weakness, fainting, bluish-colored fingernails, and convulsions. Seek immediate medical attention if these symptoms occur.

Storage

Store Tenormin tablets at room temperature, between 59-77°F (15-25°C), away from light and moisture.
