What is it used for?
It 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.
Before you are given lidocaine
You should not be given lidocaine and should tell your doctor immediately if:
- You suffer from porphyria
- You are allergic to any of the ingredients or to other local anaesthetics
You should tell your doctor if:
- You have epilepsy, any heart problems including heart failure, slow heart beat or delayed heart signals (heart block), very poor breathing, myasthenia gravis, shock, low oxygen levels or low blood volume
- The area to be anaesthetised is infected or cut
- You are pregnant, likely to become pregnant, or breast feeding
- You are taking any other medicines at all, especially ones for your heart (eg. propranolol, and medicines to treat an irregular heartbeat) or ulcers (eg. cimetidine)
- You are going to have a general anaesthetic where suxamethonium will be used.
How much is given?
The lowest dose possible will be given. The usual adult dose is 4ml (160mg). The elderly may need a lower dose. Children can be given up to 3mg for every kg they weigh (so if they weigh 10kg, they could have 3 x 10 = 30mg).
The solution can be sprayed, instilled or applied with a swab to the area to be numbed. It usually works within 5 minutes.
Since this medicine will usually be given to you by a doctor it is unlikely that you will be given too much.
However, if you are worried that you have been given too much, please tell the doctor.
Are there any side effects?
Very rarely, a patient may have an allergic reaction including rashes, swelling (particularly of the lips, face, eyelids, tongue and throat), breathlessness and collapse.
If applied in the mouth it may be difficult to swallow properly until the effect has worn off.
Other side effects may include light headedness, drowsiness, dizziness, mood changes, ringing in your ears, fear, vision difficulties such as blurred or double vision or quivering eyeballs, sickness, sensations of heat, cold or numbness, twitching, fits, shaking, unconsciousness, shallow breathing, stopping breathing, low blood pressure (feeling faint), slow heart beat, collapse including the heart stopping.
If you feel drowsy, dizzy or suffer from blurred or double vision after having lidocaine, do not drive or operate machinery.
The doctor treating you will be watching to see if these effects occur and will have the equipment to treat them.
If you think this medicine has upset you in ANY way, please tell your doctor.
