Use this medication regularly to derive the most benefit from it. Take it at the same time(s) each day and continue taking it even if you feel well, as most people with high blood pressure do not feel sick.

Consult a healthcare provider before taking Tenormin and any drug, changing any diet, or commencing or discontinuing any course of treatment.

Tenormin is contraindicated in certain conditions, including sinus bradycardia, heart block greater than first degree, cardiogenic shock, overt cardiac failure, and in patients with a history of hypersensitivity to atenolol or any of the drug product's components.

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, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

Caution should be exercised when Tenormin is administered during pregnancy or to a woman who is breastfeeding.

Adhere to these warnings and precautions and consult a healthcare provider for personalized advice and guidance regarding the use of Tenormin.
