Is thymosin alpha 1 FDA approved?

Not fully. It carries orphan drug designation in the US, a status that supports development for a rare condition but is not the same as full approval, and it is not licensed in the UK, Australia, or Canada. It is approved as Zadaxin in more than 30 other countries, mainly for hepatitis, which is why its regulatory status looks inconsistent depending on where you check.
