Twice, I spent a month in Africa, I took chloroquine as a preventative, and my husband did also, for two weeks prior to leaving the US, the time we were there and then one week after getting home, so 7 weeks, on two different trips, 14 weeks total. We had no effects from it at all, one pill a day.
I was told that the Africans take it whenever they get sick with anything as it is so harmless, and it cures many different things.
I now can't wait until I catch a common cold --- to see if it works!
I understand the dosage for covid-19 is one pill a day for 6 days. I've seen doctors say that one pill can cure it, it's certainly worth the try, and it can be prescribed as it is already PDA approved, they give prescriptions for rheumatoid arthritis and other ailments.
In answer to, is chloroquine the same as MMS, no, it's not at all.
