For at undgå forsinkelse af diagnosen og for at mindske risikoen for en livstruende overfølsomhedsreaktion, skal Trizivir seponeres permanent, hvis overfølsomhed ikke kan udelukkes, selv når andre diagnoser er mulige (luftvejssygdomme, influenzalignende sygdom, gastroenteritis eller overfølsomhed over for andre lægemidler).
To avoid a delay in diagnosis and minimise the risk of a life-threatening hypersensitivity reaction, Trizivir must be permanently discontinued if hypersensitivity cannot be ruled out, even when other diagnoses are possible (respiratory disease, flu-like illness, gastroenteritis or reactions to other medications).
