I was prescribed Hydroxychloroquine for a form of Lupus several years ago. I was very resistant to taking it, as it can cause issues with vision, and I had to also go to the eye doctor every few months for testing to make sure I wasn't losing my vision. (It is permanent).
But I gave in and started to take it 3 or so years ago. I didn't notice any change to my symptoms (which had calmed down a lot since my first diagnosis of Lupus). I saw that it cost my insurance company over $300/month for this drug which I took twice daily.
But then Covid happened, and my Rheumatologist (who prescribed it) wouldn't refill it unless I did an in-person visit, and got a dozen or so blood tests to update my labs. I didn't want to go to any doctors office in 2020, and so I decided to see how it went to go off the drug. I have not noticed any changes, now, after a year of not taking it. But I have always wondered why they would prescribe an anti malaria drug for Lupus, and it is touched on somewhat in this video, but there is not really a full explanation. I can understand for Malaria, because that is a type of parasite, which makes sense. Lupus is when your immune system goes whack.
So after watching this video, I now have a better understanding of what all the drug does (and I think I made the right decision to stop taking it). One interesting thing, I am no longer qualified for the booster (early) because I am not currently taking the Hydroxychloroquine. But I can deal with that.
At any rate, once you get over this guy's hairdo, there is a lot of good information at the cellular level of what this drug does. Thanks for posting!
