What Lignocaine Injection is used for
Lignocaine Injection belongs to two groups of medicines known as local anaesthetics and antiarrhythmic drugs. Local anaesthetics
stop pain and feeling in the area around where it is injected; and antiarrhythmic drugs work by restoring irregular and/or
rapid heart beats to normal.
Lignocaine Injection may be used for the management of other conditions that are not mentioned above. Your doctor will be
able to tell you about the specific condition for which you have been prescribed Lignocaine Injection.
This medicine is available only with a doctor's prescription.
