Som ved anden anti- hiv- medicin har patienter, der tager Trizivir, risiko for at udvikle lipodystrofi (ændringer i fordelingen af kropsfedt), immunreaktiveringssyndrom (reaktioner mod de sygdomsfremkaldende organismer i kraft af, at immunsystemet genvinder sin funktion) og osteonekrose (celledød i knoglevævet, hvilket gør knoglerne skrøbelige).
As with other anti-HIV medicines, patients taking Trizivir may be at risk of developing lipodystrophy (changes in the distribution of body fat), immune reactivation syndrome (reactions to disease-causing organisms by the recovering immune system) and osteonecrosis (death of cells in the bone, which makes the bones fragile).
