Though I did not personally employ hydroxychloroquine, the reading I have done appears to indicate it to be a low cost, inexpensive drug with a relatively good safety record.

What I actually used to great and good effect with my own family is a naturopathic compound originally called "flu-ban." The powers that shouldn't be apparently forced them to rename it d-lenolate plus. It combines olive leaf extract with other natural sources and it is utterly the most effective remedy for flu that I have ever personally encountered.
