If the hydroxychloroquine effects the Depo-Provera injection??

And what does hydroxychloroquine actually do? Xx

I don't know about the drop injection though it has never affected any birth control I have taken.
What does it do? No one completely knows the answer it is an anti malarial drug that was widely used in the Vietnam war and an incidental finding was that people with Lupus and other autoimmune diseases got dramatically better on it. On that basis it has been used widely for autoimmune diseases since. The actual mechanism of action is not understood.
