Q: What is Avigan?
A: The most promising drug against Covid-19. Developed by Fujifilm as an anti-flu drug.
Q: B-b-but I heard that it causes birth defects?
A: Birth defect is nothing but a meme. Avigan and Remdesivir make little difference in effectiveness. Both can cut recovery time remarkably.
Avigan is cheaper and easier to take as a tablet. Remdesivir is injection. Therefore US media is downplaying Avigan with the birth defect meme.
Q: What is the difference between Avigan and Favipiravir?
A: Favipiravir is a generic name for Avigan, mainly used by China to sell their knock-off products online.
Use "Avigan", the official Japanese brand name, way easier to pronounce and memorize.
