Counsel patients on 5% risk of
hypersensitivity reaction associated with
abacavir use. Reaction most often consists
of at least
two of the following:
fever, rash, nausea, vomiting, diarrhea, fatigue, and respiratory symptoms.
Patients experiencing a hypersensitivity reaction should stop antiretroviral
therapy, contact provider, and NEVER receive abacavir
again.
Lactic acidosis with hepatic steatosis is a rare but potentially fatal
toxicity associated with the use of NRTIs.
As with all antiretrovirals, adherence is
crucial. Non-adherence is a
frequent cause of drug failure and viral resistance.
