We report a 7 year old girl who developed ipsilateral left facial swelling immediately
after lignocaine injection. Skin prick test showed positive reaction to pure 2% lignocaine
hydrochloride and to lignocaine oral dental gel. Specific Immunoglobulin E (Ig E) to
lignocaine was detected. Lignocaine is a commonly used anaesthetic agent mainly as local
anaesthesia. However type I hypersensitivity to lignocaine is rare and there have been very
few cases reported in the literature.
