Product Description

Product Overview


What Labetalol Injection is for

Labetalol Injection belongs to a group of medicines called beta blockers.
Labetalol Injection works by causing the heart to beat more slowly and with less force.
It also widens the arteries in the body. This helps to lower the pressure of the blood as it travels around the body. The result is a rapid lowering of a person’s blood pressure.

Labetalol Injection is given in hospital and can be used to:
• lower very high blood pressure, especially in pregnant women;
• keep your blood pressure down during an operation;
• lower high blood pressure after a heart attack.

It is very important that the doctor treats your high blood pressure, because left untreated it can cause damage to your blood vessels in the long-term. This could lead to heart attacks, kidney failure, stroke or blindness.

Before you are given Labetalol Injection

Do not use Labetalol Injection if:
• you are allergic to labetalol hydrochloride;
• you are allergic to any of the other ingredients of Labetalol Injection ;
• your heart cannot maintain adequate circulation of blood (cardiogenic shock);
• you have heart failure that is out of control or not responding to treatment with digitalis;
• you have a heart defect that leads to a decreased function of the heart (heart block);
• your heart has difficulty pumping the proper amount of blood to the body’s tissues;
• you have a problem that is common in the elderly, related to poor control of the working of your heart (sick sinus syndrome);
• you suffer from angina (chest pains) when at rest;
• you suffer from wheezing, obstructive airways disease or asthma – taking labetalol can make your breathing worse;
• you have a tumour near your kidneys (phaeochromocytoma);
• you have increased acid levels in the blood (metabolic acidosis);
• you have a weak heart or a very slow heartbeat (less than 45 or 50 beats per minute);
• you have low blood pressure (hypotension);
• you have liver disease or your liver was affected when taking labetalol in the past;
• you have very bad circulation, especially in your hands and feet.

This medicine is not suitable for children.

If any of the above applies to you, talk to your doctor.

Check with your doctor before you are given Labetalol Injection if:
• you are about to receive an anaesthetic: as labetalol may mask the effects of a sudden loss of blood;
• you suffer or have suffered from any serious allergic reactions in the past;
• you have ever suffered from a skin condition called psoriasis;
• you have kidney or liver problems;
• you are receiving a procedure called MIBG scintigraphy (often used to detect certain tumours);
• you are elderly (65 years and over)

Tell your doctor if you are taking any of the following medicines:
• Medicines used to treat your heart or blood pressure (such as digitalis, clonidine, hydralazine, disopyramide, quinidine, amiodarone or calcium antagonists such as verapamil, diltiazem, nifedipine, ACE inhibitors, angiotensin-II antagonists, xamoterol).
• Medicines to treat depression (such as monoamine oxidase inhibitors or tricyclic antidepressants).
• Anxiolytic and hypnotic medicines for anxiety and sedation.
• NSAIDs, corticosteroids or other medicines to treat pain or inflammatory conditions.
• Cimetidine used to treat stomach ulcers.
• Insulin or oral anti-diabetic drugs.
• Anaesthetic drugs (such as cyclopropane, trichloroethylene, alcohol, barbiturates)
• Phenothiazines such as chlorpromazine.
• Antimalarial medicines such as halofantrine, mefloquine or quinine.
• Medicines for stimulating the heart e.g. adrenaline.
• Ergot derivatives used to treat Parkinson’s disease.
• Tropisetron used to treat nausea.
• Alprostadil and moxisylyte to treat impotence.
• Aldesleukin for the treatment of secondary cancer of the kidney.
• Hormones such as oestrogen and progesterone used as contraceptives or for hormone replacement therapy.
• Any other medicine, including medicines obtained without a prescription.

Taking Labetalol Injection, at the same time as the drugs mentioned for treating your heart or blood pressure, can lead to a severe drop in blood pressure, reduced heart rate, heart failure or heart block. It is important to tell your doctor if you are taking these or any of the other drugs listed above.

The results of blood or urine tests may be affected by taking labetalol. If you need to have a blood or urine test, tell your doctor that you have been given Labetalol Injection.

Labetalol Injection should only be used during the first three months of pregnancy if it is absolutely necessary. Therefore, tell your doctor if you are pregnant or trying to become pregnant.

Labetalol Injection is not recommended whilst breast-feeding.

You may feel dizzy or tired when taking Labetalol Injection. If this happens to you, do not drive or operate machinery.

How you will be given Labetalol Injection

Labetalol Injection is usually only given to patients in hospital by a doctor or anaesthetist. It may be given as an injection into a vein, or by a slow drip, depending onhow quickly your blood pressure needs to be reduced.

You should avoid sitting upright for three hours after being given Labetalol Injection as you may feel very dizzy and lightheaded.
While you are having Labetalol Injection your doctor may check your heart rate, blood pressure and breathing, to check your medicine is working properly.

Adults:

Injection into a vein (to reduce blood pressure very quickly)
• A dose of 50mg of Labetalol Injection will be given into your vein over a period of
one minute.
• If necessary this dose can be repeated every five minutes up to three times until
your blood pressure has been lowered.
• The total dose should not exceed 200mg.

Slow drip into a vein (to reduce blood pressure more slowly)
• A solution containing 1mg/ml Labetalol Injection will be made up by the doctor or nurse.
• The solution will then be given to you via a drip into your vein.
• The amount of the solution you will be given will depend on why your blood pressure needs to be lowered:

1. To lower high blood pressure in pregnancy
• 20mg of Labetalol Injection will be given over one hour.
• The dose may then be doubled every 30 minutes until your blood pressure has been reduced or the dose has reached 160mg per hour.
• Your doctor may occasionally need to use a higher dose.

2. To lower high blood pressure after a heart attack
• 15mg of Labetalol Injection will be given over one hour.
• The dose may then be gradually increased up to a maximum of 120mg per hour if needed.

3. To lower high blood pressure for other reasons
• 2mg of Labetalol Injection will be given per minute.
• When your blood pressure is low enough, the doctor will stop your drip.
• Your doctor may change the rate at which the drip goes in depending on how well you are responding to the medicine.
• The total dose given is usually between 50mg and 200mg, but occasionally higher doses may be needed.

To lower blood pressure during an operation
• Whilst you are under anaesthetic, 10-20mg Labetalol Injection (depending on your age and health) will be injected into your vein.
• If after five minutes your blood pressure has not been reduced, a dose of 5-10mg can be given every five minutes until your blood pressure is low enough.

Maintaining your blood pressure
• After you have had Labetalol Injection your doctor may suggest you take labetalol tablets to keep your blood pressure low.
• If this applies to you, your doctor or pharmacist will tell you exactly how many tablets to take and when to take them.

People with liver or kidney problems:
If you have problems with your liver or kidneys, your doctor may give you a lower dose of Labetalol Injection.
