Atenolol is a beta-blocker that works by blocking the effects of adrenaline on the heart and blood vessels. It is primarily used to treat high blood pressure (hypertension), angina (chest pain), and to prevent heart attacks.
Dosage and Administration:
Atenolol is available in different strengths, including 25 mg, 50 mg, and 100 mg tablets. The dosage may vary depending on the specific condition being treated and individual patient factors. The following dosage information is a general guideline:
- High Blood Pressure: The usual starting dose is 50 mg once daily, which may be increased to 100 mg per day if necessary. In some cases, higher doses may be prescribed.
- Angina: The typical starting dose is 50 mg once daily. Your doctor may adjust the dose based on your response and symptoms.
- Heart Attack Prevention: Atenolol is usually initiated as a 50 mg dose within the first 12 hours of a heart attack. The treatment duration may vary, so follow your doctor’s instructions.
It is essential to take atenolol as prescribed by your doctor. Do not change the dosage or stop taking it without consulting your healthcare provider.
Possible Side Effects:
Like any medication, atenolol can cause side effects, although not everyone experiences them. Common side effects may include fatigue, dizziness, cold hands or feet, slowed heart rate, low blood pressure, and gastrointestinal disturbances.
If you experience severe or persistent side effects, or any allergic reactions (e.g., rash, itching, swelling), seek medical attention promptly.
Precautions:
Before taking atenolol, inform your doctor about any medical conditions you have, especially asthma, chronic obstructive pulmonary disease (COPD), heart failure, diabetes, liver or kidney problems, and any allergies you may have. Also, disclose all medications, supplements, or herbal products you are taking as they may interact with atenolol.
