Atenolol

Generic Name: atenolol (a TEN oh lol)
Brand Names: Tenormin

What is atenolol?

Atenolol (Tenormin) is a beta-blocker that affects the heart and circulation (blood flow through arteries and veins).

Atenolol is used to treat angina (chest pain) and hypertension (high blood pressure).

Atenolol is also used to lower the risk of death after a heart attack.

Important information
You should not use this atenolol if you have a serious heart condition such as "AV block," very slow heartbeats, or heart failure.

Do not stop taking atenolol without first talking to your doctor. Stopping suddenly may make your condition worse.

If you need to have any type of surgery, you may need to temporarily stop using atenolol. Be sure the surgeon knows ahead of time that you are using this medicine.

Atenolol can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert. Avoid drinking alcohol, which could increase drowsiness and dizziness while you are taking atenolol.

Atenolol is only part of a complete program of treatment for hypertension that may also include diet, exercise, and weight control. Follow your diet, medication, and exercise routines very closely if you are being treated for hypertension.

If you are being treated for high blood pressure, keep using this medication even if you feel fine. High blood pressure often has no symptoms. You may need to use blood pressure medication for the rest of your life.

Before taking this medicine
You should not use atenolol if you are allergic to it, or if you have:

a serious heart condition such as "AV block" (second or third degree);
very slow heartbeats; or
heart failure.
To make sure atenolol is safe for you, tell your doctor if you have:

congestive heart failure;
coronary artery disease (hardened arteries);
asthma, bronchitis, emphysema;
diabetes;
overactive thyroid;
liver or kidney disease;
pheochromocytoma (tumor of the adrenal gland);
peripheral vascular disease such as Raynaud's syndrome; or
allergies (or if you are undergoing allergy treatments or skin-testing).
Using atenolol during pregnancy could harm the unborn baby. Tell your doctor if you are pregnant or if you become pregnant while using this medicine.

Atenolol can pass into breast milk and may harm a nursing baby. Tell your doctor if you are breast-feeding a baby.

Atenolol is not approved for use by anyone younger than 18 years old.


How should I take atenolol?
Take atenolol exactly as it was prescribed for you. Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Your blood pressure will need to be checked often.

If you need surgery, tell the surgeon ahead of time that you are using atenolol. You may need to stop using the medicine for a short time.

It may take up to 2 weeks before you get the full effect of atenolol. Keep using the medication as directed and tell your doctor if your symptoms do not improve.

You should not stop taking atenolol suddenly. Stopping suddenly may make your condition worse.

If you are being treated for high blood pressure: Keep using this medicine even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medicine for the rest of your life.

Your condition may need to be treated with a combination of drugs. Use all medications as directed by your doctor. Read the medication guide or patient instructions provided with each medication. Do not change your doses or medication schedule without your doctor's advice.

What is Aricept?

Aricept (donepezil) improves the function of nerve cells in the brain. It works by preventing the breakdown of a chemical called acetylcholine (ah SEET il KOE leen).

Aricept is used to treat mild to moderate dementia caused by Alzheimer's disease.

Aricept is not a cure for Alzheimer's disease. This condition will progress over time, even in people who take donepezil.

Amiodarone

Generic Name: amiodarone (oral) (A mi OH da rone)
Brand Names: Cordarone, Pacerone

What is amiodarone?

Amiodarone affects the rhythm of your heartbeats. It is used to help keep the heart beating normally in people with life-threatening heart rhythm disorders of the ventricles (the lower chambers of the heart that allow blood to flow out of the heart).

Amiodarone is used to treat ventricular tachycardia or ventricular fibrillation.

Amiodarone is for use only in treating life-threatening heart rhythm disorders. You will receive your first few doses in a hospital setting, where your heart rhythm can be monitored using an electrocardiograph or ECG (sometimes called an EKG).

Important information
Amiodarone is for use only in treating life-threatening heart rhythm disorders.

You should not take this medicine if you are allergic to amiodarone or iodine, or if you have a serious heart condition such as "AV block" (unless you have a pacemaker), a history of slow heart beats, or if your heart cannot pump blood properly.

This medicine can cause dangerous side effects on your liver or your lungs.

Call your doctor at once if you have: chest pain, trouble breathing, upper stomach pain, dark urine, jaundice (yellowing of the skin or eyes), or if you cough up blood.

Do not use amiodarone without telling your doctor if you are pregnant. It could harm the unborn baby. Use effective birth control, and tell your doctor if you become pregnant during treatment.

To be sure this medication is not causing harmful effects, your blood may need to be tested on a regular basis. Your thyroid and liver function may also need to be tested, and you may need eye exams and chest x-rays. Do not miss any scheduled appointments.

Before taking this medicine
You should not use this medicine if you are allergic to amiodarone or iodine, or if you have:

certain serious heart conditions, especially "AV block" (unless you have a pacemaker);
a history of slow heart beats that have caused you to faint; or
if your heart cannot pump blood properly.
Amiodarone can cause dangerous side effects on your heart, liver, lungs, or thyroid.

To make sure amiodarone is safe for you, tell your doctor if you have:

asthma or another lung disorder;
liver disease;
a thyroid disorder;
vision problems;
high or low blood pressure;
an electrolyte imbalance (such as low levels of potassium or magnesium in your blood); or
if you have a pacemaker or defibrillator implanted in your chest.
Do not use amiodarone if you are pregnant. Taking amiodarone during pregnancy can harm the unborn baby or cause thyroid problems or abnormal heartbeats after the baby is born. Amiodarone may also affect the child's growth or development (speech, movement, academic skills) later in life. Use effective birth control to prevent pregnancy during treatment.

Amiodarone can pass into breast milk and may harm a nursing baby. You should not breast-feed while using this medicine.


How should I take amiodarone?
Take amiodarone exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.

If you have been taking another heart rhythm medicine, you may need to gradually stop taking it when you start using amiodarone. Follow your doctor's dosing instructions very carefully.

You may take this medicine with or without food, but take it the same way each time.
