Nadolol

Brand names: Corgard

Why is Nadolol prescribed?

Corgard is used in the treatment of angina pectoris (chest pain, usually caused by lack of oxygen to the heart due to clogged arteries) and to reduce high blood pressure.

When prescribed for high blood pressure, it is effective when used alone or in combination with other high blood pressure medications. Corgard is a type of drug known as a beta blocker. It decreases the force and rate of heart contractions, reducing the heart's demand for oxygen and lowering blood pressure.

Most important fact about Nadolol

If you have high blood pressure, you must take Corgard regularly for it to be effective. Since blood pressure declines gradually, it may be several weeks before you get the full benefit of Corgard; and you must continue taking it even if you are feeling well. Corgard does not cure high blood pressure; it merely keeps it under control.

How should you take Nadolol?

Corgard can be taken with or without food. Take it exactly as prescribed even if your symptoms have disappeared.

Try not to miss any doses. Corgard is taken once a day. If it is not taken regularly, your condition may worsen.

  • If you miss a dose...Take it as soon as you remember. If it is within 8 hours of your next scheduled dose, skip the one you missed and go back to your regular schedule. Never take 2 doses at the same time.
  • Storage instructions...Store at room temperature, away from light and heat, in a tightly closed container.

What side effects may occur?

Side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible. Only your doctor can determine if it is safe for you to continue taking Corgard.

  • Side effects may include:Change in behavior, changes in heartbeat, dizziness or light-headedness, mild drowsiness, slow heartbeat, weakness or tiredness

Why should Nadolol not be prescribed?

If you have a slow heartbeat, bronchial asthma, certain types of heartbeat irregularity, cardiogenic shock (shock due to inadequate blood supply from the heart), or active heart failure, you should not take Nadolol.

If you have a history of congestive heart failure, your doctor will prescribe Corgard with caution.
