I don't wear dentures, but I have 4 caps, 1 crown, 1 implant. I was diagnosed with mai, and prescribed rifampin, azithromycin, and ethambutol. i am concerned about the yellowing that may occur. if my eyes turn yellow, will it go away? or is it permanent? i know that the coloring of the dentures is permanent. i would love to hear about any alternatives i can pursue. the ethambutal might cause joint pain and i already have arthritis in my joints. will that go away if i experience that side effect? thanks so much.
