What is in this leaflet
This leaflet answers some common questions about Presolol.
It does not contain all of the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have benefits and risks. 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.

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 necessary, 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. Presolol helps to lower your blood pressure.
Presolol 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.
Your doctor may have prescribed Presolol for another reason. Ask your doctor if you have any questions about why Presolol
has been prescribed for you.
Presolol is not recommended for use in children, as its safety and effectiveness have not been established in this age group.
Presolol is available only with a doctor's prescription.
There is no evidence that Presolol is addictive.

Do not use Presolol to treat any other conditions unless your doctor tells you to.

Dizziness, lightheadedness or fainting may occur, especially when you get up quickly from a sitting or lying down position.
Getting up slowly may help.
Make sure you drink enough water in hot weather and during exercise when you are taking Presolol, especially if you sweat
If you do not drink enough water while taking Presolol, you may feel faint or lightheaded or sick. This is because your blood
pressure is dropping suddenly. If you continue to feel unwell, tell your doctor.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Presolol.
