Tamiflu.
It was one of the things that went on shortage when there was the big SARS/Avian flu scare or whatever it was a few years back, along with the N95 grade micron filtration masks that can actually catch an Influenza virus... That and the antibiotic Cipro during the Anthrax scares way back during the 9/11 time-frame...
There's arguments if it even works. Roche hasn't released all their data. There has been an independent review by some other groups that says it's not complete bunk. If it does work, it certainly won't "cure" a case of the flu, if it is helping, it might knock down the the duration/severity to just a few days. It's best use seems at least statistically, to take the edge off and help mitigate the potential for serious complications like pneumonia. It's supposed to prevent the virus from cutting ties with the host cells that have been hijacked into producing more so they don't spread as much.
Although some complain Tamiflu hasn't even gone head-to-head with Aspirin and Tylenol in proper double-blind controlled studies to see how effective it is as compared to very common drugs and supportive therapy, like just keeping an eye on people and keeping them hydrated. Because symptomatic treatments could just as easily be as beneficial to the person's overall health and keeping them from getting sicker etc.
You do have to see the doctor within the first 48 hours I think for it to be the most effective. After that the virus has spread too far or is already inside too many cells forcing them to churn out copies that the inhibitions the drug provides won't help much.
