Prophylactic Use of Antivirals
Oseltamivir Tamiflur® is a neuraminidase
inhibitor that has been approved for use for post-exposure
prophylaxis against influenza A and/or B in persons ≥ 1 year of
age. Two trials on post-exposure prophylaxis showed a relative
efficacy of 58%94 and 89%95 of oseltamivir compared with controls in
preventing symptomatic, laboratory-confirmed influenza (an absolute
risk reduction of 15% and 11%, respectively) The efficacy of
oseltamivir in preventing influenza has not been established in
immunocompromised persons and those with significant renal
diseases, hepatic dysfunction, cardiac failure or cancer, as these
groups were excluded from clinical trials. No randomized trials
have been conducted to assess the efficacy of oseltamivir in
controlling outbreaks in LTCFs. However, the results of
observational studies of outbreaks in LTCFs have been promising
when oseltamivir was used for both treatment and prophylaxis, along
with vaccination and infection control measures. The use of
oseltamivir is currently contraindicated in children < 1 year of
age as their blood-brain barrier is not fully developed and, on the
basis of animal studies, there is a concern that this could lead to
toxicity. The emergence of oseltamivir-resistant virus during or
after prophylactic use of this antiviral has not yet been reported.
However, 0.33% to 18% of influenza isolates have been noted to be
oseltamivir resistant during follow-up of children and adults in
treatment studies.
What is the shelf life of the pills?
The expiry date is mentioned on each blister. It is different for different batches. The shelf life is 2 years from the date of manufacture and would differ from batch to batch depending on when they were manufactured.
Good Morning:
