For at undgå at forsinke diagnosticering og for at mindske risikoen for en livstruende overfølsomhedsreaktion, skal Ziagen 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, Ziagen must be permanently discontinued if hypersensitivity cannot be ruled out, even when other diagnoses are possible (respiratory diseases, flu-like illness, gastroenteritis or reactions to other medications).
