1. WHAT LABETALOL IS AND WHAT IT IS USED FOR
Labetalol contains the active substance labetalol. It is used to treat severe hypertension (high blood pressure), including severe hypertension of pregnancy (pregnancy-induced high blood pressure) when rapid control of blood pressure is necessary. Labetalol may also be used to control blood pressure during anaesthesia.
Labetalol belongs to a group of medicines called alpha and beta-blocking agents. These medicines lower blood pressure by blocking the receptors in the cardiovascular (circulatory) system, causing a decrease in blood pressure in the blood vessels far from the heart.
2. WHAT YOU NEED TO KNOW BEFORE YOU ARE GIVEN LABETALOL DO NOT TAKE LABETALOL
- if you are allergic to labetalol or any of the other ingredients of this medicine (listed in section 6)
- if you have certain heart diseases for example heart block or sick sinus syndrome (unless you have a pacemaker), cardiogenic shock or heart failure which is not under the control
- if you have ongoing low blood pressure
- If you have an extremely slow heart rate (severe bradycardia)
- if you have a condition known as Prinzmetal angina
if you have asthma or similar lung disease (obstructive airway disease)
- if you have a particular type of tumour of the adrenal gland (phaeochromocytoma), untreated with an adequate pharmacologic therapy (see section ?Warning and Precautions?)
Warnings and Precautions
Talk to your doctor or pharmacist before you take Labetalol:
- if you have reduced liver function or liver damage
- if you have reduced kidney function
- if you have peripheral vascular disease, for example, Raynaud’s syndrome, intermittent claudication
- if you have diabetes mellitus (type 1 or type 2)
- if you have an overactive thyroid (thyrotoxicosis, hyperthyroidism)
- if you have previously had a severe allergic reaction (anaphylaxis) to any substance
- if you have heart failure or other problems with your heart (for example; poor left ventricular systolic function, first-degree atrioventricular block)
- if you know you are scheduled to have an operation
- if you have metabolic acidosis (when your body produces too much acid or when the kidneys are not removing enough acid from your body) and phaeochromocytoma
- if you have a condition called ischaemic heart disease
- if you have any lung or respiratory system problems
If you develop a low heart rate (bradycardia) as a result of being given Labetalol, your doctor may lower your dose.
If you develop skin rashes and/or dry eyes, or any kind of allergic reaction when you are being given Labetalol, tell your doctor as they may reduce or discontinue your treatment.
Surgery
If you are having surgery requiring general anaesthetic, you must tell your surgeon ahead of your surgery that you are using Labetalol as labetalol may mask the effects of a sudden loss of blood.
Labetalol can affect your pupils during cataract surgery. Tell your eye surgeon ahead of your surgery that you are using this medication. Do not stop using labetalol before surgery unless your surgeon tells you to.
Tests
This medicine may interfere with certain medical tests/laboratory tests and possibly causing false test results. Make sure laboratory personnel and all your doctors know you use this medicine.
Children and adolescents

- general anaesthetics (used in surgery for narcosis)
- tricyclic anti-depressants for example; imipramine (used for the treatment of depression)
- oral antidiabetics, for example; biguanides (e.g. metformin), sulfonylureas (e.g. glimepiride), meglitinides (e.g. repaglinide), and ?-glucosidase inhibitors (e.g. acarbose) which are used to lower glucose levels in the blood
- ergotamine derivates, for example; ergotamine or dihydroergotamine which are used to treat migraine
- cholinesterase inhibitors, for example, donepezil, galantamine or rivastigmine which are used for the treatment of mild cognitive impairment, Alzheimer’s disease and Parkinson’s disease

Pregnancy, breast-feeding and fertility

Labetalol is excreted in breast milk in small amounts. If you are breast-feeding, ask your doctor for advice before you are given Labetalol.

3. HOW LABETALOL IS GIVEN
Labetalol should always be used as instructed by your doctor. Labetalol is intended for intravenous treatment in hospitalised patients and should be administered by healthcare personnel.
It is important that you are lying down when the injection is being given to you. You will be asked to remain lying down for three hours after you have received Labetalol as you may get dizzy (from low blood pressure) if you move to an upright position sooner than this. Labetalol can either be given as a bolus injection (where the medicine is injected directly into a vein) or an intravenous infusion (where the medicine is injected directly into a vein over a longer period of time). Your doctor will decide how Labetalol should be administered and what dose of Labetalol that you should be given.
If you are given more Labetalol than you should
Symptoms of Labetalol overdose include extreme dizziness when you move to an upright position (sitting or standing) and sometimes low heart rate which you will feel like a slow pulse (bradycardia).
Contact a doctor or nurse if you think you have been given too much of this medicine.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
