What is Atenolol?
Atenolol is a medication used to treat high blood pressure. It also can be used to treat
chest pain(angina), an irregular heart rate (Afib) and is used in the early treatment
after a heart attack. It is also used off label to treat migraines. It can be also used off
label to treat a thyroid emergency called thyrotoxicosis. It belongs to a family of
medications called Beta blockers. The brand name for Atenolol is Tenormin.
How does Atenolol work?
Like other beta blockers,
Atenolol works by slowing down your heart rate and making it easier for your heart to pump blood
around your body. Atenolol does this by changing the way your body responds to some nerve impulses.
Atenolol dosing and administration:
Usually, Atenolol is taken orally once daily. You can take this medication with or without food. The
doses in its tablet form as at follows: 25mg, 50mg and 100mg.You should start the dose at the lowest
dose (especially if you are older) and if need be, increase the dose weekly based on how you tolerate
the medication, side effects profile as well as the dose response from the medication. It’s Ok
to take this medication at nighttime as long as you are taking it at the same time every day.
The starting dose of this medication depends on what pathology your health care provider
is treating. If they are treating angina (chest pain) some providers start at a higher dose of
50mg for symptom management. The starting dose for both high blood pressure and atrial fibrillation
is usually at 25mg.If you use Atenolol as a blood pressure medication it is recommended another
treatable co-morbidity such as heart attack or hx of a heart attack is also being managed.

1) This drug is going to lower your BP and lower your heart rate (bradycardia). This might make you feel
dizzy when you suddenly get up. Take your time when you are getting up esp. from a sitting
position. Be careful going up and down stairs. 2) Atenolol can affect your blood sugars. If you
are a diabetic continue to carefully monitor your blood sugars as it can cause low blood sugars.
Symptoms of low blood sugar are fast heart rate, dizziness, sweating and feeling shaky.
3) Atenolol can cause bronchospasms. Symptoms would be difficulty breathing and wheezing.
Although because of the way Atenolol works (it works over a B1 receptor),
the chance of this happening is less likely. However, if you have a bronchospastic disease
such as Asthma you would be more susceptible to this. Tell your health care provider
if you do have increasing cough, wheezing or shortness of breath.. 4) Beta blockers such as Atenolol do have CNS effects.
They can cause fatigue, insomnia (1-3%) and in some cases sleep disturbances (3%), this
is because Beta Blockers slow down you heart rate and you will feel more tired as your heart rate slows down.
Because of this you may want to take your first doses of Atenolol at nighttime
as it can make you feel sleepy. Once you are used to the medication you can switch to the morning
with the help of your health care provider. 5) Avoid drinking alcohol
while taking this medication. 6) This drug has been associated in
the worsening of psoriasis. If you have any of these changes alert your health care provider.

GI symptoms such as diarrhea and nausea . These are usually self-limiting and should go away.

He or she can reintroduce the medication once your heart failure is compensated.
