1. What Lidocaine is for
Lidocaine belongs to a group of medicines called local anaesthetics. Local anaesthetics work by numbing the area of the body that they are injected into which stops pain being felt.
Lidocaine is used to numb parts of the body, such as the mouth, throat and lungs, before some medical procedures which would otherwise be uncomfortable or painful. Examples of the kind of procedures Lidocaine is used for are putting a breathing tube in during an operation, putting a tube into the lungs to examine them (bronchoscopy), or taking a specimen from the mouth, throat or lungs.
2. Before you are given Lidocaine
Do not have Lidocaine if:
• You are allergic to Lidocaine or other local anaesthetics
• You are allergic to any of the other ingredients of Lidocaine (see section 6)
• You have acute porphyria (a blood disorder in which excessive blood pigment, porphyrin is excreted in the urine and you are extremely sensitive to light).
If any of the above applies to you talk to your doctor or nurse.
Check with your doctor before you are given Lidocaine if:
• You have epilepsy
• You have liver disease
• You have any heart problems
• You have severe breathing difficulties
• You have myasthenia gravis (a condition where you have weak muscles)
• You suffer from loss of blood circulation or less oxygen in the tissue
• You have unusually low or high levels of potassium in the blood
• The area to be anaesthetised is infected or cut
• You are pregnant, likely to become pregnant, or are breast-feeding
• You are suffering from shock. This is an emergency condition where there is not enough oxygen
reaching all parts of the body. This type of shock can cause many organs to stop working properly.
Tell your doctor if you are taking any of the following medicines:
• Any medicines for a heart condition (e.g. kinidine, disopyramide, amiodarone, bretylium, sotalol,
dofetilide, metoprolol and nadolol)
• Medicines for high blood pressure (e.g. propanolol)
• Medicines for a stomach ulcer (e.g. cimetidine)
• Medicines for epilepsy (e.g. phenytoin), infections (e.g. erythromycin), depression (e.g. fluvoxamine) or glaucoma (e.g. acetazolamide)
• Oral contraception or oral HRT
• Suxamethonium or cistracurium used as muscle relaxants during a general anaesthetic
• Medicines to increase the rate of urination (e.g. loop diuretics or thiazides)
• You are taking any other medicine, including medicines obtained without a prescription If any of the above applies to you talk to your doctor or nurse.
Pregnancy and breast-feeding
If you are pregnant, in labour or breastfeeding, Lidocaine will only be given to you if your doctor considers that the benefit of treatment outweighs the risk to the developing baby or new-born baby. Lidocaine is excreted in breast milk, so if you are breastfeeding, your doctor or nurse will observe your baby for any side effects.
Driving and using machines
Lidocaine may make you feel dizzy or tired. If this happens to you, do not drive a vehicle, operate machinery or carry out complex tasks.
3. How Lidocaine will be given to you Important:
Lidocaine will be given to you by a doctor, or nurse in hospital. Your doctor will choose the dose that is right for you.
The solution can be sprayed, instilled or applied with a swab to the area to be numbed. It usually works within 5 minutes.
Adults
The lowest dose possible will be given. The usual adult dose is 1 to 5 ml (40 - 200mg).
The elderly
The elderly may need a lower dose.
Children
The usual dose is up to 3mg for every kg they weigh (so if they weigh 10kg, they could have 3 x 10 = 30mg).
If you think you may be given more Lidocaine than you should
As this medicine will be given to you by a doctor or nurse, it is unlikely that you will be given too little or too much. However, tell your doctor or nurse if you have any concerns.
The effects of an overdose may include fits (convulsions) and/or collapse of the heart and circulatory system.
