Cutaneous reactions with tenofovir disoproxil fumarate: A report of nine cases

Adverse drug reactions causing the early discontinuation of therapy are common in patients with HIV infection. Hypersensitivity consisting mainly of a maculopapular rash on the face, extremities and trunk has been observed at a rate higher than expected in patients treated with tenofovir at our clinics. We therefore examined nine patients with suspected tenofovir hypersensitivity reactions in two indigent care HIV clinics. Type I and type IV hypersensitivity may be involved as immunological mechanisms.
