Identification

Generic Name
Bromothalonil
DrugBank Accession Number
DB14199
Background

Bromothalonil, also known as Methyldibromo glutaronitrile (MDBGN), is a widely used preservative that can be found in many personal hygiene and industrial products. It is also a known allergen and dermatological irritant that has been banned in many EU countries due to increasing rates of contact allergy 1. In 2005, MDBGN was named in the top 15 most frequently positive allergens identified in patch tests by the North American Contact Dermatitis Group (NACDG)3.

Sensitivity to Bromothalonil may be identified with a clinical patch test.
