I recall it coming up recently. One of mine is sick with I'm not sure what yet. We're a just-be-sick family. No flu shots, no flu tests, Tamiflu hadn't crossed my mind, honestly. If it's obviously viral, we just stay home and rest, stay fluid-filled, and take Vitamin C (and now monolaurin). Just wait it out. Good hygiene, etc. None of us are at risk for complications, afaik.
But a relative has suggested the Tamiflu route. Sounds great! Catch it early, greatly reduce severity and length of infection... But could it be like antibiotics except with antivirals, where overuse could contribute to diminishing returns and eventually resistant strains?
