Lower blood pressure: Atenolol is a beta blocker- works by blocking the heart's response to Adrenalin (epinephrine). Chlorthalidone is a diuretic- works at the kidney level to reduce volume in the blood vessels. The combination drug is called tenoretic. Atenolol's brand name is tenormin. Chlorthalidone's brand name is hygroton (chlorthalidone).

Is it dangerous for a heart failure patient to abruptly discontinue atenolol?

Depends: If the heart failure is due to coronary disease, then abrupt discontinuation of a beta blocker could be a problem. If there is a compelling reason to hold the beta blocker in other circumstances, it can be held; just remember that beta blockers are important adjuncts to heart failure treatment, so coordinate with the doctors.

A 40-year-old member asked:

Is it necessary to wean off atenolol 75mg? Am switching to verapamil sr 120mg. Was advised that no wean is necessary. Stop atenolol, start verapamil?

Depends: The worry about not weaning off atenolol 75 is that you can develop reflex tachycardia (rapid heartbeat) - the rationale in your case is that the verapamil should counter this making it unnecessary to wean.
A 37-year-old member asked:

How much Tenormin (atenolol) can I take to control severe anxiety?

Consult your doc: Atenolol is a 'cardioselective' beta-blocker. In layman's terms, it blocks the effects of adrenaline on the heart, and blunts the 'fight or flight' syndrome that anxiety-sufferers often needlessly find themselves in. This bodily response to anxiety (rapid heart rate, sweating) can further promote anxiety, a self-perpeuating cycle. Too high a dose can dangerously lower hr & bp, so consult your doc!

A 38-year-old male asked:

Does stopping 50mg atenelol cause chest pains?

1 doctor answer3 doctors weighed in
Dr. Steven Ajluni
Cardiology 35 years experience
CP can occur : Chest pain can be due to sudden discontinuation of beta blockers due to a rebound activation of the sympathetic nervous system (with outpouring of catecholamines, the heart can race, BP can spike, resulting in discomfort and shortness of breath).
