Yes it is Hydroxychloroquine Sulfate. I have left over pills for when I was taking it for RA 5 years ago. Expired med!
Right now there is a terrible shortage of Plaquenil or Hydroxychloroquine Sulfate. People with lupus and Rheumatoid Arthritis. That is who this drug is supposed to be for. They could die with it.
Further, I have read all the latest information, and Plaquenil does NOT work prophylacticly for COVID-19
IOW you are wasting a drug that is in short supply, needed for autoimmune people, and perhaps for people who have COVID-19. There still are no good studies that say it works, just anecdotal reports.
I was on Plaquenil for a year. I had no side effects. But other people I know have had reactions. This is not doctor supplied, so what will you do if you have a severe allergic reaction. Do you know you need to check with an ophthalmologist, every year for 5 years to make sure you aren't going blind from this drug?
You need to go off and not take it unless you get real COVID-19 symptoms. And feel bad that you are wasting a supply of the drug for nothing. It will not provide you with any immunity, or blocking the virus. Just a complete waste of a drug for people who really need it, for helping a medical condition, that many people do have!
