I've seen testing up to 10 years after expiry with similar efficacy and a quick google suggests the FDA extended that to 20 years recently
Often causes pretty dreadful vomiting, and it's not clear whether it would be of great benefit in the event of a highly pathogenic flu, but it's the standard treatment for the avian flus
(A meta-analysis did find that it didn't reduce hospitalisation, but it's hard to translate to findings given most people taking Tamiflu are going to be at a high risk)
how long can it be stored?
