MAYO CLINIC ON-LINE


HLA-B*5801 Testing for Allopurinol Severe Cutaneous Adverse Reactions
hla-b5801-hot-topicAllopurinol is a widely used treatment for hyperuricemia-related diseases, but the drug carries the risk of severe adverse cutaneous drug reactions including Stevens Johnson syndrome and toxic epidermal necrolysis. This hypersensitivity reaction to allopurinol has been linked to the HLA-B*5801 allele, which is present in both susceptible and healthy individuals at frequencies that vary by ethnicity. Pretreatment testing for HLA-B*5801, in either blood or saliva, can help identity those at risk for these complications.
