Tenormin

Pronounced: Ten-OR-min
Generic name: Atenolol

Why is Tenormin prescribed?

Tenormin, a type of medication known as a beta blocker, is used in the treatment of high blood pressure, angina pectoris (chest pain, usually caused by lack of oxygen in the heart muscle due to clogged arteries), and heart attack. When used for high blood pressure it is effective alone or combined with other high blood pressure medications, particularly with a thiazide-type water pill (diuretic). Beta blockers decrease the force and rate of heart contractions.

Occasionally doctors prescribe Tenormin for treatment of alcohol withdrawal, prevention of migraine headache, and bouts of anxiety.

Most important fact about Tenormin

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

How should you take Tenormin?

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

Try not to miss any doses, especially if you are taking Tenormin once a day. If this medication is not taken regularly, your condition may worsen.

--If you miss a dose...

Take the forgotten dose as soon as you remember. If it's 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 Tenormin at room temperature; protect from light.

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 Tenormin.

• More common side effects may include:
  Dizziness, fatigue, nausea, slow heartbeat

Why should Tenormin not be prescribed?

If you have heart failure, inadequate blood supply to the circulatory system (cardiogenic shock), heart block (conduction disorder), or a severely slow heartbeat, you should not take this medication. You'll also need to avoid it if it gives you an allergic reaction.
