What Deralin is used for
Deralin 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.
Deralin contains the active ingredient propranolol hydrochloride, which belongs to a group of medicines called beta-blockers.
Deralin is used to treat or prevent a number of conditions. These include:
•hypertension (high blood pressure)
•heart beat or heart rhythm irregularities, including those caused by anxiety or an overactive thyroid gland
•essential tremor (shaking of head, chin, hands)
•phaeochromocytoma, a rare tumour of the adrenal gland
(only when used in combination with another medicine)
•heart attack prevention or treatment, or to reduce the risk of heart problems after a heart attack
•migraine headache prevention.
Ask your doctor if you have any questions about why Deralin has been prescribed for you.
Your doctor may have prescribed Deralin for another reason.
Deralin is available only with a doctor's prescription.

The starting dose is 10mg taken once or twice daily. This can be increased if necessary.
Your doctor will tell you what dose to take.

Follow your doctor's instructions carefully.
How to take Deralin
Swallow the tablets with a glass of water.
When to take Deralin
Deralin can be taken with or without food.
If you forget to take Deralin
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 the missed dose as soon as you remember, and then go back to taking your tablets as you would normally.
Do not take a double dose to make up for the dose you missed.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.
How long to take Deralin for
To properly control your condition, Deralin must be taken every day.
Keep taking Deralin for as long as your doctor recommends. Do not stop taking Deralin, or lower the dose, without checking with your doctor.
If you take too much Deralin (overdose)
Immediately telephone your doctor, or the Poisons Information Centre (telephone 13 11 26), or go to Accident and Emergency at the nearest hospital, if you think you or anyone else may have taken too much Deralin.
Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
If you take too much Deralin, you may feel faint, very tired, have a slow heart beat or have difficulty breathing.
While you are taking Deralin
Things you must do
Before starting any new medicine, tell your doctor or pharmacist that you are taking Deralin.
Tell all the doctors, dentists and pharmacists who are treating you that you are taking Deralin.
If you become pregnant while taking Deralin, tell your doctor immediately.
If you have or have had 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 Deralin may cause allergic reactions to be worse and harder to treat.
If you plan to have surgery (including dental surgery) that requires a general anaesthetic, tell your doctor or dentist that you are taking Deralin.
Your blood pressure may drop suddenly if Deralin interacts with the anaesthetic.
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 Deralin.
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.
Since Deralin is meant to be taken regularly every day, keep a continuous supply of medicine so you don't run out, especially over weekends or on holidays.
If you are being treated for diabetes, make sure you check your blood glucose level regularly and report any changes to your doctor.
Deralin may affect how well your diabetes is controlled. Deralin may hide some signs of low blood glucose levels (hypoglycaemia) such as increased heart rate.
It may also prolong the blood glucose lowering effect of your diabetic medicine or increase the time it takes for your body to recover from low blood glucose. Your doctor therefore may need to adjust the dose of your insulin or diabetic medicines.
Deralin 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
Visit your doctor regularly so they can check on your progress.
Things you must not do
Do not stop taking Deralin, or lower the dose, without checking with your doctor.
Stopping Deralin suddenly may worsen your angina or cause other heart complications to occur. Your doctor will tell you how to gradually reduce the amount of Deralin you are taking before stopping completely. This may help reduce the possibility of your condition getting worse.
Do not use Deralin to treat any other conditions unless your doctor tells you to.
Do not give Deralin to anyone else, even if they have the same condition as you.
Things to be careful of
Be careful driving or operating machinery until you know how Deralin affects you.
Deralin is unlikely to affect your ability to drive or operate machinery. However, as dizziness or fatigue have occasionally occurred in some people, do not drive, operate machinery or do anything else that could be dangerous until you know how Deralin affects you.
Be careful drinking alcohol while taking Deralin.
Combining Deralin and alcohol can make you more dizzy or lightheaded. Alcohol can also increase the effects of Deralin.
Make sure you drink enough water in hot weather and during exercise, especially if you sweat a lot.
If you do not drink enough water while taking Deralin, you may feel faint, lightheaded or sick. This is because your blood pressure is dropping suddenly. If you continue to feel unwell, tell your doctor.
Dress warmly during cold weather, especially if you will be outside for a long time.
Deralin, like other beta-blocker medicines tend to make you more sensitive to cold temperatures, especially if you have circulation problems.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Deralin.
Deralin helps most people and is usually well tolerated, but it may have unwanted side effects in some 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.

This medicine may cause low blood sugar levels (hypoglycaemia) in some people.
This may occur in people being treated with insulin and other medicines for diabetes, but occasionally can also occur in the newly born, infants, children, the elderly, people who are fasting, undergoing haemodialysis, suffering from chronic liver disease or from an overdose.
