Low incidence of abacavir hypersensitivity reaction among African children initiating antiretroviral therapy

Hypersensitivity reactions are reported in approximately 5% of adults receiving abacavir, but there are few published data in children. Among 1150 African children receiving antiretroviral therapy in a randomized trial, suspected hypersensitivity reactions to abacavir were rare (0.3%; 95% CI, 0.01-0.9). Patients were managed successfully through the provision of clear guidelines and education of clinical staff, children, and their caregivers.
