Abstract
Abacavir is a nucleoside reverse transcriptase inhibitor used in combination therapy for the treatment of the human immunodeficiency virus type 1 (HIV-1) that has been associated with a hypersensitivity reaction in approximately 8% of those starting the drug.
Abacavir hypersensitivity reaction is characterized by greater than or equal to two progressive symptoms typically starting from the second week of therapy (median 9 days) with fever, malaise, nausea, vomiting, diarrhea, and later mild-to-moderate skin rash (present in 70% of patients).
Symptoms of abacavir hypersensitivity resolve rapidly with 24 to 72 hours after drug discontinuation.
A previous clinical history compatible with abacavir hypersensitivity is a contraindication to future rechallenge as severe morbidity and even mortality characterized by hypotension and shock has been described.
