Frequently asked questions

Can I stop atenolol if I feel fine?

No — stopping suddenly can trigger chest pain or a fast heartbeat. Your doctor will reduce it gradually if needed.

Why are my hands and feet cold on atenolol?

Beta-blockers slow the heart and can reduce blood flow to the hands and feet. Tell your doctor if it is severe.

Is atenolol safe with kidney disease?

Atenolol is cleared by the kidneys, so your doctor may lower the dose or choose another beta-blocker.
