Authors' objectives:

This report investigates the evidence about the use of two neuraminidase inhibitors (NIs), zanamivir (Relenza) and oseltamivir (Tamiflu), for the prophylaxis of influenza. What is the evidence for effectiveness in termsof demonstrated harm (side effects and drugresistance) and benefit from oseltamivir andzanamivir prophylaxis (post-exposure, outbreak, seasonal or prolonged) versus other medical care or no prophylaxis against influenza, including avian influenza, for people with or without underlying health conditions, long-term care residents, health care workers with or without close patient contact, household contacts, and public health responders?

Authors' recommendations: There is enough evidence to conclude that the antiviral drugs zanamivir and oseltamivir are effective in preventing the acquisition of common LCI, and are well tolerated by healthy humans and those whose health is compromised (the elderly and those living in LTCF). There is no evidence about prophylaxis among very young children, pregnant women, or HCWs, though there is no reason to expect that HCWs would respond differently from other healthy people. There is no strong evidence that these drugs provide protection against ILIs. These agents are most effective inproviding seasonal prevention, though there is a dearth of evidence on the safety of prophylactic use after a few weeks. The evidence in this report reflects data from seasonal influenza and isolated outbreak situations; it may be impossible to generalize to a pandemic scenario. There is no evidence on the use of these drugs for public health responders and HCWs, and no evidence about the drugs- performance in post-exposure prophylaxis for people with underlying health conditions.
