Plaquenil is the preferred medication for Lupus.
Plaquenil, also known as hydroxychloroquine.
(Which ofc is why it was dicovered as a treatment in the first place - all the Lupus sufferers being immune to Covid)
Plaquinil is HCQ. My sister was on it for years. She has Lupus and told me you can’t take the vaccine if you have an immunosuppresent condition. Not that she would take it anyway.
