What INDERAL is for
INDERAL 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 therefore reduces the amount of work the heart has to do. It also widens the blood vessels in the body, as well as helping the heart to beat more regularly.
INDERAL belongs to a group of medicines called beta-blockers.
INDERAL tablets are used to treat or prevent a number of conditions, most of which are related to the heart.
- to lower high blood pressure, also called hypertension
- to prevent angina
- to treat or prevent heart attacks, or reduce your risk of heart problems following a heart attack
- to treat irregularities in heart beat, including those caused by anxiety
- essential tremor (shaking of head, chin, hands)
- Fallot's Tetralogy
- to prevent migraine headaches
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed this medicine for another reason.
INDERAL is not addictive.
It is only available with a doctor's prescription.

How to take INDERAL
How much to take
For high blood pressure
The usual starting dose is one 40 mg tablet taken twice a day for one week.
The dose is then usually increased to between 120 mg to 320 mg daily.
If you are taking other medicines which lower blood pressure, your doctor may need to change the dose of them to obtain the best results for you.
For angina and tremor
The usual dose is 40 mg taken two or three times a day.
To treat or prevent heart attack
The usual dose is 80 mg taken twice a day, often starting with 40 mg taken four times a day for 2 or 3 days.
For migraine prevention
The usual dose is 40 mg taken twice a day. This may need to be increased up to 80 mg twice a day.
Children over 7 years
The starting dose is 10 mg taken once or twice daily. This can be increased if necessary.
Your doctor will tell you what dose to take.
Your doctor may tell you to take a different amount of INDERAL to the one given in this leaflet.
Follow your doctor's instructions carefully.
If you forget to take it
If it is almost time for your next dose (within 6 hours), skip the dose you missed and take your next dose when you are meant to. Otherwise, take it as soon as you remember, and then go back to taking your tablets as you would normally.
Do not double the dose.
If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.
Taking too much (overdose)
Telephone your doctor, the Poisons Information Centre (13 11 26) or go to Accident and Emergency at your nearest hospital immediately if you think that you or anyone else may have taken too much INDERAL even if there are no signs of discomfort or poisoning.
If you take too many INDERAL tablets you will probably feel very tired, have difficulty breathing and moving around.
While you are using Inderal
Things you must do
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking INDERAL.
Tell any doctors, dentists, and pharmacists who are treating you that you are taking this medicine.
If you have a severe allergic reaction to foods, medicines or insect stings, tell your doctor immediately.
If you have a history of allergies, there is a chance that INDERAL may cause
allergic reactions to be worse and harder to treat.
If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly.
You may feel light-headed or dizzy when you begin to take INDERAL.
Standing up slowly, especially when you get up from bed or chairs, will help your body get used to the change in position and blood pressure. If this problem gets worse or continues, talk to your doctor.
If you plan to have surgery (even at the dentist) that needs a general anaesthetic, tell your doctor or dentist that you are taking INDERAL. Your blood pressure may drop suddenly if INDERAL interacts with the anaesthetic.
If you become pregnant while taking INDERAL, tell your doctor.
If you are being treated for diabetes, make sure you check your blood sugar level regularly and report any changes to your doctor. INDERAL may change how well your diabetes is controlled. It may also cover up some of the symptoms of low blood sugar (hypoglycaemia) such as increased heart rate.
INDERAL may increase the time your body takes to recover from low blood sugar. Your doses of diabetic medicines, including insulin, may need to change.
INDERAL may also occasionally cause low blood sugar (hypoglycaemia) in non-diabetic patients. These may include the newly born, toddlers, children, elderly, patients suffering from overdose, patients suffering from chronic liver disease, fasting patients or patients on haemodialysis.
Things you must not do
Do not give INDERAL to anyone else even if they have the same condition as you.
Do not use INDERAL to treat any other complaints unless your doctor tells you to.
Do not stop taking INDERAL without checking with your doctor. Your doctor may want you to gradually reduce the amount of INDERAL you are taking before stopping completely. This may help reduce the possibility of your condition getting worse.
Things to be careful of
Be careful driving or operating machinery until you know how INDERAL affects you. INDERAL may cause dizziness, light-headedness, tiredness, or drowsiness in some people. Make sure you know how you react to INDERAL before you drive a car, operate machinery, or do anything else that could be dangerous if you are dizzy or light-headed.
Be careful drinking alcohol while you are taking INDERAL. Dizziness or light-headedness may be worse. Alcohol can also increase the effects of INDERAL.
Dress warmly during cold weather, especially if you will be outside for a long time (for example when playing winter sports). INDERAL, like other beta-blocker medicines, may make you more sensitive to cold temperatures, especially if you have circulation problems.
Please talk to your doctor or pharmacist about these possibilities if you think they may bother you.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking INDERAL.
INDERAL helps most people when taken correctly, but it may have unwanted side-effects in a few people.
All medicines can 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.

- unexplained bruising
- mood changes, confusion
- sexual problems

These are all serious side effects. You may need urgent medical attention.

If any of the following happen, stop taking INDERAL and tell your doctor immediately or go to Accident and Emergency at your nearest hospital.
- extreme tiredness or breathlessness on mild exercise
- wheezing, difficulty breathing or an asthma attack
- fast heart beats (palpitations)
These are very serious side effects. If you have them, you may have had a serious (allergic) reaction to INDERAL. You may need urgent medical attention or hospitalisation.
All of these side effects are very rare.
Tell your doctor if you notice anything else that is making you feel unwell. Other side effects not listed above may also occur in some people.
After using INDERAL
