Generic name: Atenolol
Why is Atenolol prescribed?
Atenolol, 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 Atenolol for treatment of alcohol withdrawal,
prevention of migraine headache, and bouts of anxiety.
Most important fact about Atenolol without prescriptions
If you have high blood pressure, you must take Atenolol regularly
for it to be effective. Since blood pressure declines gradually, it
may be several weeks before you get the full benefit of Atenolol; and
you must continue taking it even if you are feeling well. Atenolol
does not cure high blood pressure; it merely keeps it under control.
How should you take Atenolol?
Atenolol 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 Atenolol once
a day. If Atenolol 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...
