What Lopresor is used for
Lopressor is used:
1. to lower high blood pressure, also called hypertension
2. to prevent a type of chest pain, also called angina
4. to prevent migraine headaches
Everyone has blood pressure. This pressure helps to move your blood around your body.
Your blood pressure may be different at various times of the day, depending on how
busy you are. You have hypertension (high blood pressure) when your blood pressure
stays higher than is needed, even when you are calm and relaxed. If high blood pressure
is not treated it can lead to serious health problems, including stroke, heart disease
and kidney failure.
There are usually no symptoms of hypertension. The only way of knowing that you have
it is to have your blood pressure checked on a regular basis. You may feel fine and
have no symptoms but, if high blood pressure is not treated, it can lead to serious
health problems. Lopresor helps to lower your blood pressure.
Angina is a pain or uncomfortable feeling in the chest, often spreading to the arms
or neck and sometimes to the shoulders and back. This may be caused by too little
blood and oxygen getting to the heart. The pain of angina is usually brought on by
exercise or stress but it can also happen while you are resting. Lopresor helps to
prevent angina from happening. It is not used to treat a sudden attack.
Reducing heart complications after heart attack
After a heart attack there is a chance of developing complications such as an irregular
heartbeat (also called an arrhythmia) or another heart attack. Lopresor helps to prevent
these conditions from happening.
This is a throbbing headache, usually affecting one side of the head and often accompanied
by nausea, vomiting and sensitivity to light.
Lopresor belongs to a group of medicines called beta-blockers. It works by affecting
the body's response to some nerve impulses, especially in the heart. As a result,
it decreases the heart's need for blood and oxygen and reduces the amount of work
that the heart has to do. It also widens the blood vessels in the rest of the body.
Lopresor can be used alone or in combination with other medicines to treat your condition.
Ask your doctor if you have any questions about why this medicine has been prescribed
Your doctor may have prescribed it for another reason.
Lopressor is not recommended for use in children.
Lopresor is only available with a doctor's prescription.
It is not addictive.

food, continue taking it with food every day.
How long to take it
Continue taking Lopresor for as long as your doctor tells you to.
Lopresor helps to control your symptoms but it does not cure your condition. Your
doctor will check your progress to make sure the medicine is working and will decide
how long your treatment should continue.

If you forget to take it
If it is almost time for your next dose (eg. within 2 or 3 hours), skip the dose you
missed and take your next dose when you are meant to.
Otherwise, take the dose as soon as you remember, and then go back to taking it as
you would normally.
Do not take a double dose to make up for the one that you missed.
This may increase the chance of you getting an unwanted side effect.
If you have trouble remembering when to take your medicine, ask your pharmacist for

very low blood pressure, slow heartbeat, difficulty breathing, fainting, convulsions

Take extra care when exercising, driving or standing for long periods, especially
in hot weather. Drink plenty of fluids, especially if you sweat a lot.
If you are being treated for diabetes, make sure you check your blood sugar regularly
and report any problems to your doctor.
Lopresor may change how well your diabetes is controlled. It may also prevent some
of the warning signs of low blood sugar, such as fast heart beat, and may make low
blood sugar last longer. The dose of your diabetes medicines may need to be changed.

that you are taking Lopresor.

that you are taking Lopresor.

Things you must not do

Your doctor may want to gradually reduce the amount of Lopresor you are taking before
stopping it completely. This helps to reduce the chance of your condition becoming
worse or keep other unwanted heart problems from happening.
Do not use Lopresor to treat any other complaints unless your doctor says you can.
Do not give this medicine to anyone else, even if their symptoms seem to be similar
Things to be careful of
Be careful driving, operating machinery or doing jobs that require you to be alert
while you are taking Lopresor until you know how it affects you.

or decreased alertness in some people.
If you have any of these symptoms, do not drive or do anything else that could be
Be careful to dress warmly during cold weather, especially if you will be outside
for a long time.
Like other beta-blocker medicines, Lopresor may make you more sensitive to cold temperatures,
especially if you have problems with your blood circulation. These medicines tend
to decrease blood circulation in the skin, fingers and toes.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you
are taking Lopresor.
All medicines have side effects. Sometimes they are serious, most of the time they
are not. You may need medical treatment if you get some of the side effects. If you
