1. What Trandate Injection is for
Trandate Injection belongs to a group of medicines called beta blockers.
Trandate 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. Trandate
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.
2. Before you are given Trandate Injection
Do not use Trandate Injection if:
• you are allergic to labetalol hydrochloride;
• you are allergic to any of the other ingredients of Trandate Injection (see section 6);
• 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 Trandate 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.

3. How you will be given Trandate Injection
Trandate 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 on how quickly your
blood pressure needs to be reduced.
Your doctor will decide how the Trandate Injection will be given to you and the correct
dose for you.
Remember: You should only be given this drug if you are lying down.
You should avoid sitting upright for three hours after being given Trandate Injection as you
may feel very dizzy and lightheaded.
While you are having Trandate Injection your doctor may check your heart rate, blood pressure
and breathing, to check your medicine is working properly.
Injection into a vein (to reduce blood pressure very quickly)

A dose of 50mg of Trandate Injection will be given into your vein over a period of one

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 Trandate 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 Trandate 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 Trandate Injection will be given over one hour.
• The dose may then be gradually increased up to a maximum of 120mg per hour if

To lower high blood pressure for other reasons
• 2mg of Trandate 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 Trandate Injection (depending on your age and
health) will be injected into your vein.

given every five minutes until your blood pressure is low enough.
Maintaining your blood pressure
• After you have had Trandate Injection your doctor may suggest you take Trandate 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.

Technical Leaflet intended for healthcare professionals only

Trandate 5mg/ml Solution for Injection is for single use only. Once opened, the product should
be used immediately. Discard any unused material.

Trandate Injection is indicated for the treatment of:
1. Severe hypertension, including severe hypertension of pregnancy, when rapid control of
blood pressure is essential.
2. Anaesthesia when a hypotensive technique is indicated.
3. Hypotensive episodes following acute myocardial infarction.
Trandate Injection is intended for intravenous use in hospitalised patients. The plasma
concentrations achieved after intravenous dose of Trandate in severe hypertension are
substantially greater than those following oral administration of the drug and provide a greater
degree of blockade of alpha-adrenoceptors necessary to control the more severe disease.
Patients should, therefore, always receive the drug whilst in the supine or left lateral position.
Raising the patient into the upright position, within three hours of intravenous Trandate
administration, should be avoided since excessive postural hypotension may occur.
Bolus injection
If it is essential to reduce blood pressure quickly, as for example, in hypertensive
encephalopathy, a dose of 50mg of Trandate should be given by intravenous injection over a
period of at least one minute. If necessary, doses of 50mg may be repeated at five minute
intervals until a satisfactory response occurs. The total dose should not exceed 200mg. After


bolus injection, the maximum effect usually occurs within five minutes and the effective
duration of action is usually about six hours but may be as long as eighteen hours.
Intravenous infusion
An alternative method of administering Trandate is intravenous infusion of a solution made by
diluting the contents of two ampoules (200mg) to 200ml with Sodium Chloride and Dextrose
Injection BP or 5% Dextrose Intravenous Infusion BP. The resultant infusion solution contains
1mg/ml of Trandate. It should be administered using a paediatric giving set fitted with a 50ml
graduated burette to facilitate dosage.
In the hypertension of pregnancy: The infusion can be started at the rate of 20mg per hour
and this dose may be doubled every thirty minutes until a satisfactory reduction in blood
pressure has been obtained or a dosage of 160mg per hour is reached.
Occasionally, higher doses may be necessary.
In hypertensive episodes following acute myocardial infarction: The infusion should be
commenced at 15mg per hour and gradually increased to a maximum of 120mg per hour
depending on the control of blood pressure.
In hypertension due to other causes: The rate of infusion of Trandate should be about 2mg
(2ml of infusion solution) per minute, until a satisfactory response is obtained; the infusion
should then be stopped. The effective dose is usually in the range of 50-200mg depending on
the severity of the hypertension. For most patients it is unnecessary to administer more than
200mg but larger doses may be required especially in patients with phaeochromocytoma. The
rate of infusion may be adjusted according to the response, at the discretion of the physician.
The blood pressure and pulse rate should be monitored throughout the infusion.
It is desirable to monitor the heart rate after injection and during infusion. In most patients,
there is a small decrease in the heart rate; severe bradycardia is unusual but may be controlled
by injecting atropine 1-2mg intravenously. Respiratory function should be observed
particularly in patients with any known impairment.
Once the blood pressure has been adequately reduced, maintenance therapy with Trandate
tablets should be instituted with a starting dose of one 100mg tablet twice daily (see Trandate
tablet SmPC for further details). Trandate Injection has been administered to patients with
uncontrolled hypertension already receiving other hypotensive agents, including beta blocking
drugs, without adverse effects.
In hypotensive anaesthesia: Induction should be with standard agents (e.g. sodium
thiopentone) and anaesthesia maintained with nitrous oxide and oxygen with or without
halothane. The recommended starting dose of Trandate Injection is 10-20mg intravenously
depending on the age and condition of the patient. Patients for whom halothane is contraindicated usually require a higher initial dose of Trandate (25-30mg). If satisfactory
hypotension is not achieved after five minutes, increments of 5-10mg should be given until the
desired level of blood pressure is attained.
Halothane and Trandate act synergistically therefore the halothane concentration should not
exceed 1-1.5% as profound falls in blood pressure may be precipitated.


Following Trandate Injection the blood pressure can be quickly and easily adjusted by altering
the halothane concentration and/or adjusting table tilt. The mean duration of hypotension
following 20-25mg of Trandate is fifty minutes.
Hypotension induced by Trandate Injection is readily reversed by atropine 0.6mg and
discontinuation of halothane.
Tubocurarine and pancuronium may be used when assisted or controlled ventilation is required.
Intermittent Positive Pressure Ventilation (IPPV) may further increase the hypotension
resulting from Trandate Injection and/or halothane.

Safety and efficacy have not been established.
Trandate Injection has been shown to be incompatible with sodium bicarbonate injection BP
4.2% w/v.
Protect from light. Store below 30°C.
For single use only. Discard any unused material.
Shelf life: Unopened: 24 months
Once opened, the product should be used immediately.
