Lidocaine / Lignocaine + Tetracaine is primarily used to numb small areas of skin prior to minor medical procedures and belongs to the group of local anaesthetic medicines.

Lidocaine / Lignocaine + Tetracaine is a combination used as a local anaesthetic.
Lidocaine / Lignocaine works by blocking nerve signals in the area it is applied. This helps in reducing the sensation of pain by stopping these signals from reaching the brain. It provides quick onset of numbness.
Tetracaine, on the other hand, also works by blocking nerve signals of pain, but it provides a longer-lasting numbing effect.
