Consumer Medicine Information
What is in this leaflet
This leaflet answers some common questions about PRESOLOL. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you taking PRESOLOL against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, talk to your doctor or pharmacist.
Keep this leaflet with your medicine.
You may need to read it again.
What PRESOLOL is used for
PRESOLOL contains the active ingredient labetalol hydrochloride and is used to lower high blood pressure, also called hypertension.
Everyone has blood pressure. This pressure helps to circulate your blood all around your body. Your blood pressure may be different during different times of the day, depending on how busy or worried you are. You have hypertension (high blood pressure) when your blood pressure stays higher than normal, even when you are calm and relaxed.
There are usually no symptoms of hypertension. The only way of knowing that you have hypertension 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.
This medicine belongs to a group of medicines called beta-blockers. These medicines work by changing the body’s response to some nerve impulses. As a result, it widens blood vessels in the body causing blood pressure to fall.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed PRESOLOL for another reason.
There is not enough information to recommend the use of this medicine in children. Safety and effectiveness have not been established in this age group.
This medicine is available only with a doctor’s prescription.
There is no evidence that PRESOLOL is addictive.

The dose of PRESOLOL varies from patient to patient.
The usual adult starting dose is 100 mg to 200 mg twice daily.
Your doctor may change this dose depending on how you respond to this medicine. Your doctor will decide the right dose for you.
Elderly patients may need smaller doses.

If you forget to take it
If it is almost time for your next dose, 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 medicine as you would normally.
Do not take a double dose to make up for the dose you missed.
This may increase the chance of you getting an unwanted side effect.
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.
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital if you think that you or anyone else may have taken too much PRESOLOL. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.

While you are taking PRESOLOL
Things you must do
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking PRESOLOL.
Tell any other doctors, dentists and pharmacists who treat you that you are taking this medicine.
If you are going to have surgery, tell the surgeon or anaesthetist that you are taking this medicine.
It may affect other medicines used during surgery.
If you become pregnant while taking this medicine, tell your doctor immediately.
If you have a severe allergic reaction to foods, medicines or insect stings, tell your doctor immediately.

Immediately stop taking this medicine if a skin rash or any other allergic reaction occurs.
If you are being treated for diabetes, make sure you check your blood sugar level regularly.
PRESOLOL may affect how well your diabetes is controlled. It may also hide some of the symptoms of low blood sugar (also called hypoglycaemia) such as a fast heart beat. PRESOLOL may also make low blood sugar last longer.
Your doctor may need to change your dose of diabetic medicines, including insulin.
If you are about to have any blood tests, tell your doctor that you are taking this medicine.
It may interfere with the results of some tests.
Keep all of your doctor’s appointments so that your progress can be checked.
Things you must not do
Do not take PRESOLOL to treat any other complaints unless your doctor tells you to.
Do not give your medicine to anyone else, even if they have the same condition as you.
Do not stop taking your medicine or change the dosage without checking with your doctor.
Stopping PRESOLOL suddenly may cause unwanted heart problems. Your doctor may want you to gradually reduce the amount of Presolol you are taking before stopping completely. This may help reduce the possibility of heart complications from occurring.
Things to be careful of
Be careful driving or operating machinery until you know how PRESOLOL affects you.
This medicine may cause drowsiness, dizziness or lightheadedness in some people. If you have any of these symptoms, do not drive, operate machinery or do anything else that could be dangerous.
If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly.
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 continues, or gets worse, talk to your doctor
Make sure you drink enough water in hot weather and during exercise when you are taking this medicine, especially if you sweat a lot.
If you do not drink enough water while taking PRESOLOL, you may feel faint, lightheaded or sick (nauseous). This is because your blood pressure is dropping suddenly.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking PRESOLOL.
This medicine helps most people with high blood pressure, 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.
