INFORMATION LEAFLET
INDERAL INJECTION
(propranolol hydrochloride)
Please read
this leaflet carefully. This leaflet only gives a
summary of the information available on your medicine.
If you have any questions or are not sure about
anything, ask your doctor or pharmacist.
WHAT YOU
SHOULD KNOW ABOUT YOUR MEDICINE
The name of
your medicine is Inderal Injection. The active
ingredient is propranolol. Inderal Injection contains 1
mg of propranolol hydrochloride in 1 ml of injection.
Your medicine also contains the following inactive
ingredients: citric acid and water. Inderal Injection is
produced in packs containing 10 ampoules of 1 ml.
Propranolol is one of a group of drugs called
beta-blockers. It has effects on the heart and
circulation and also on other parts of the body.
Inderal
Injection is used for the emergency treatment of some
arrythmias (disorders of heart rhythm) and certain
thyroid conditions (such as thyrotoxic crisis which is
caused by an overactive thyroid gland).
BEFORE
RECEIVING YOUR MEDICINE
If you have ever had asthma or
wheezing, YOU SHOULD NOT BE GIVEN INDERAL INJECTION.
Talk to your doctor.
Inderal
Injection should not be given if you have previously had
an allergic reaction to it, to propranolol, or to any of
the other ingredients listed above.
Inderal
Injection should also not be given to people with heart
failure which is not under control or people with
certain other conditions such as heart block, very slow
or very irregular heart beats, very low blood pressure
or very poor circulation. It should also not be given to
people who are fasting or have been fasting recently,
people who have phaeochromocytoma (high blood pressure
due to a tumour usually near the kidney) which is not
being treated or to people who have metabolic acidosis
or a particular type of chest pain called Prinzmetal’s
angina. Your doctor will know about these conditions. If
you have one of these conditions, make sure your doctor
knows about it before you are given Inderal.
Do you get
allergic reactions to such things as insect stings? If
so, tell your doctor.
Do you have
diabetes? Inderal may change your normal response to low
blood sugar, which usually involves an increase in heart
rate. Inderal may cause low blood sugar levels even in
patients who are not diabetic.
Do you
suffer from unstable angina (non-exercise induced sharp
chest pain)?
Do you have
thyrotoxicosis? Inderal may hide the symptoms of
thyrotoxicosis.
Do you have
kidney or liver problems (including cirrhosis of the
liver)? If so, talk to your doctor because you may need
to have some check ups during your treatment.
Do you have
any other health problems such as circulation disorders,
heart problems, breathlessness or swollen ankles? If so,
tell your doctor.
Are you
taking any other medicines? If so, tell your doctor.
Inderal can interfere with the action of some other
drugs and some drugs can have an effect on your
medicine. The drugs which can cause some problems when
taken together with your medicine are verapamil,
diltiazem, nifedipine, nisoldipine, nicardipine,
isradipine, lacidipine (which are used to treat
hypertension or angina), disopyramide, lignocaine,
quinidine or propafenone (for irregular heart beats),
digoxin (for heart failure), adrenaline (a heart
stimulant), ibuprofen and indomethacin (for pain and
inflammation), ergotamine and dihydroergotamine (for
migraine), chlorpromazine and thioridazine (for certain
psychiatric disorders), cimetidine (for stomach
problems), rifampicin (for the treatment of
tuberculosis), theophylline (for asthma), warfarin (to
thin the blood) and hydralazine (for hypertension).
If you
frequently drink a lot of alcohol, this may reduce the
effect of your medicine.
Are you
taking a drug called clonidine (for hypertension or
migraine)? If you are taking clonidine and Inderal
together, you must not stop taking clonidine unless your
doctor tells you to do so. If it becomes necessary for
you to stop taking clonidine, your doctor will give you
careful instructions on how to do it.
If you go
into hospital to have an operation, tell the
anaesthetist or the medical staff that you are being
given Inderal.
Are you
pregnant or are you breast feeding a baby? If so, tell
your doctor.
Your
medicine is unlikely to affect your ability to drive or
to operate machinery. However, some people may
occasionally feel dizzy or tired when taking Inderal. If
this happens to you, ask your doctor for advice.
RECEIVING YOUR MEDICINE
The
injection is normally given in emergency situations.
Your doctor will have decided what dose you should be
given depending on your condition. The usual dose for an
adult is 1 mg injected into a vein. This can be repeated
if necessary up to a maximum dosage of 10 mg. When
Inderal Injection is used to treat children, the dosage
will be adjusted by the doctor according to the child’s
age or weight.
Elderly
patients may be started on a lower dose.
AFTER
RECEIVING YOUR MEDICINE
As with all
medicines, undesirable events can sometimes be
experienced with Inderal. When Inderal is given as
tablets over a long time, occasionally, a few people can
suffer from cold hands and feet, tiredness, slow heart
beat, nausea, diarrhoea, disturbed sleep, thinning of
the hair, mood changes, confusion, psychoses or
hallucinations, bruising more easily or purplish marks
on the skin, tingling of the hands, dry eyes,
disturbances of vision, muscle weakness, skin rashes,
worsening of psoriasis or dizziness particularly when
standing up, low blood sugar (hypoglycaemia) in children
who do not have diabetes. Other possible events which
may occur in susceptible people are numbness and spasm
in the fingers (Raynaud’s phenomenon), heart block
(which can cause dizziness or fainting), worsening of
heart failure (breathlessness and/or swollen ankles) in
people with heart failure, worsening of breathing
difficulties in people with asthma or breathing problems
or worsening of the circulation in people with poor
circulation.
Low levels
of blood sugar may occur in diabetic and non-diabetic
patients including the newborn, toddlers and children,
elderly patients, patients on artificial kidneys
(haemodialysis) or patients on medication for diabetes.
It may also occur in patients who are fasting or have
been fasting recently or in patients who have a long
term liver disease.
Do not be
alarmed by this list of possible events. You may not
have any of these, especially since you are being given
the injection for only a short time.
If you get
any other undesirable events or if you think your
medicine is causing any problems, tell your doctor or
pharmacist.
STORING
YOUR MEDICINE
Your
medicine should not be used after the expiry date on the
carton.
Your
