Drug class
Beta Blockers: medications in this class
Medications that reduce heart rate and blood pressure by blocking beta-adrenergic receptors.
Overview
Beta blockers block the effect of adrenaline on the heart, slowing the rate and reducing the force of contraction. For heart failure and after a heart attack they improve survival; for angina they reduce the heart’s oxygen demand; for atrial fibrillation they control the rate. Propranolol is also used for migraine prevention, tremor and situational anxiety.
They are no longer a first choice for high blood pressure alone, but they remain essential where there is heart disease. Metoprolol, carvedilol and bisoprolol have the heart failure evidence; atenolol and propranolol are older and still widely used. The class should not be stopped suddenly after long use, because rebound can cause angina or a rhythm disturbance.
Fatigue, cold hands, slow pulse, dizziness and, in asthma, bronchospasm are the things to watch. They can mask the warning signs of low blood sugar in people with diabetes.
How the drugs in this class differ when you pay cash
The tablets are commodity generics, but the forms differ in price: metoprolol tartrate (twice daily) and metoprolol succinate extended-release (once daily) are different products, and the extended-release carvedilol capsule costs far more than the twice-daily tablet. A prescription written for the convenient once-daily form can cost far more per month than the twice-daily tablet.
Brand Toprol-XL and Coreg CR are the same molecules at higher prices. For most patients the cheapest route is the plain tablet at a flat-price pharmacy on a ninety-day fill.
When paying cash beats a copay, and when it does not
For the immediate-release tablets, a cash quote is usually at or below a copay. The extended-release forms are where comparing matters: generic prices vary widely between pharmacies, and insurance can be cheaper for them.

Questions worth asking
- Is this the twice-daily tablet or the once-daily extended-release form?
- Would the twice-daily tablet be acceptable for me if it is much cheaper?
- What pulse rate is too slow, and what should I do about dizziness?
- Does this affect my asthma or my ability to notice low blood sugar?
- What happens if I run out or stop suddenly?
