1. WHAT LIDOCAINE HYDROCHLORIDE IS AND WHAT IT IS USED FOR

Lidocaine Hydrochloride is a local anaesthetic and belongs to a class of drugs called amide type local anaesthetics. It produces loss of feeling or sensation confined to one part of the body.

Lidocaine Hydrochloride Injection may be used to produce local numbness (anaesthesia) by injection of the solution into or around the area of operation. It may also be used to produce local anaesthesia by injection of the solution close to the nerves whose conduction is to be cut off, or into the epidural space near the spinal cord, or by administering the solution into a vein in a limb that has been isolated from the circulation by means of a tourniquet (bandage that stops the flow of blood from vessel by applying pressure).

2. WHAT YOU NEED TO KNOW BEFORE YOU ARE GIVEN LIDOCAINE HYDROCHLORIDE

You should not be given this medicine:

  • if you know you are allergic to lidocaine hydrochloride, to any of the other ingredients of this medicine (listed in section 6) or to other similar amide type anaesthetics
  • if you suffer from state of decreased blood volume (hypovolaemia)
  • if you suffer from abnormality of impulse propagation in the heart causing decreased blood pressure, slow heart rate (complete heart block)
  • If the solution also contains adrenaline, lidocaine hydrochloride should not be injected into a vein or used in areas such as fingers, toes, ears, nose or penis, as the blood supply to these areas might become inadequate

Speak to your doctor if one of these applies to you before you are given this medicine.

  • you suffer from any heart problem, particularly if it affects the heart rate
  • you suffer from fits (epilepsy)

4. POSSIBLE SIDE EFFECTS

Like all medicines, Lidocaine Hydrochloride can cause side effects, although not everyone gets them.

All medicines can cause allergic reactions although serious allergic reactions are rare.

Any sudden wheeziness, difficulty in breathing, swelling of the eyelids, face or lips, rash or itching (especially affecting your whole body) should be reported to a doctor immediately. Lidocaine may result in abnormal amount of methemoglobin (a form of hemoglobin in blood) which may cause bluish discoloration of skin, headache, shortness of breath, malaise and fatigue.

Other serious side effects are also rare, but may occur if too much Lidocaine Hydrochloride is given or if the drug is unintentionally injected into a blood vessel.

Such side effects may occur with certain frequency, which is defined as follows:

Not known: frequency cannot be estimated from the available data

  • changes in the rhythm and speed of the heart
  • low blood pressure
  • slow heart rate (less than 60 beats/minute)
  • cessation of normal circulation of blood due to failure of the heart
  • pain at the injection site, or numbness or loss of power after the effects of the injection should have worn off
  • temporary pain sensation at the lower back, buttocks, legs which resolves within a few days
  • numbness or tingling/paralysis of legs after administration of lidocaine in the spine
  • difficulty in passing water, problems with the frequency, consistency and/or ability to control your bowel movements (bowel dysfunction)
  • loss of balance, pins and needles around the mouth, numbness of the tongue, difficulty tolerating everyday sounds (hyperacusis), ringing in the ears (tinnitus), dizziness or lightheadedness, confusion, nervousness, restless or twitching, changes in your normal mood or behaviour, involuntary rhythmic muscular contractions, fits or seizures, profound state of unconsciousness (coma)
  • allergic reaction to local anaesthetic e.g. a skin rash or breathlessness or collapse
  • feelings of anxiety or fear
  • blurred vision, double vision or transient visual loss
  • feeling sick (nausea) or being sick (vomiting)
  • breathlessness
  • cessation of breathing (respiratory arrest)
  • feeling drowsy or faint.

Note : If you are having a blood test, tell your doctor, as injection of lidocaine into a muscle can increase the blood levels of an enzyme marker for muscle damage.

If any of the side effects become serious, or if you notice any side effects not listed in this leaflet, please tell your doctor or pharmacist.
