<p>Elderly Patients or Patients with Renal Impairment: Atenolol is excreted by the kidneys; consequently dosage should be adjusted in cases of severe impairment of renal function. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, refecting greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. The following maximum oral dosages are recommended for elderly, renal impaired patients and for patients with renal impairment due to other causes:</p>

<ul>
	<li>Creatinine clearance 15-35 ml/min/1.73 m2: Maximum dosage 50 mg daily</li>
	<li>Creatinine clearance &lt;15 mL/min/1.73 m2: Maximum dosage 25 mg daily</li>
</ul>

<p>Some renal impaired or elderly patients being treated for hypertension may require a lower starting dose of Atenolol: 25 mg given as one tablet a day. Patients on hemodialysis should be given 25 mg or 50 mg after each dialysis; this should be done under hospital supervision as marked falls in blood pressure can occur.</p>
