Background – Life-threatening allergic reactions (anaphylaxis) in
relation to dental treatment are rare. The diagnosis may be difficult
to make, but it is important to identify and treat anaphylaxis
promptly. Symptoms from airways and/or circulation, and occasionally
from the gut, are usually accompanied by skin symptoms
e.g. itch, rash or swelling. The treatment is intramuscular adrenalin
0,3 mg, repeated if needed. Allergy investigations should be
carried out to identify the culprit.
Case study – This case describes a young woman who developed
anaphylaxis after rinsing with chlorhexidine following a routine dental
check. Shortly after rinsing she developed vomiting, diarrhoea,
dizziness and fainting associated with a rash. She responded well
to intramuscular adrenalin and is brought to the hospital. Allergy
investigations confirm allergy to chlorhexidine.
Conclusion – This case illustrates the need for recognizing anaphylaxis
promptly and the importance of rapid and correct treatment
of these life-threatening reactions. It also draws attention to
chlorhexidine allergy; a rare allergy, which must not be overlooked.
