For most people with high blood pressure or angina, the suggested starting dose of atenolol is 50 mg once a day. The maximum daily dosage for controlling high blood pressure is 100 mg, while the maximum daily dose for treating angina symptoms is 200 mg. Following a heart attack, atenolol is given in the hospital through an intravenous line (IV). Your healthcare provider may start you on a lower dosage if you have kidney disease or failure, or are over the age of 65.
The dose of atenolol (Tenormin®) your healthcare provider prescribes will vary, depending on a number of factors, including:
- Your age
- The medical condition you are being treated for
- Other medical conditions you may have
- Other medications you may be currently taking.
As always, do not adjust your dosage unless your healthcare provider specifically instructs you to do so.
The recommended starting dosage of atenolol for people with high blood pressure (hypertension) is 50 mg once a day. After a couple of weeks, based on the blood pressure response and/or atenolol side effects, the dosage may be increased or decreased. Your healthcare provider may also add a diuretic (which is a "water pill") or another blood pressure medication if your blood pressure is not controlled by atenolol alone.
The maximum recommended daily atenolol dose for high blood pressure treatment is 100 mg. Higher doses are not likely to be any more effective.
The recommended starting dosage for people with angina is atenolol 50 mg, taken once a day. After one week, based on the response and/or side effects, your healthcare provider may increase or decrease your dosage.
The maximum daily dose for treating angina symptoms is atenolol 200 mg.
