The mechanism of hydroxychloroquine retinal toxicity has yet to be fully elucidated. Studies have shown that the drug affects the metabolism of retinal cells and also binds to melanin in the RPE, which could explain the persistent toxicity after discontinuation of the medication. Jan 05, 2020 Hydroxychloroquine binds to melanin, accumulates in the RPE, and remains there for long periods of time. It is directly toxic to the RPE, causing cellular damage and atrophy 2. This occurs due to disruption of RPE metabolism, specifically from lysosomal damage 5, and reduced phagocytic activity toward shed photoreceptor outer segments.

The mechanism is unknown. Combining telbivudine Tyzeka and hydroxychloroquine may increase the risk of unexplained muscle pain, tenderness, or weakness because both drugs cause such side effects. Hydroxychloroquine suppresses the immune system and should not be combined with drugs that also suppress the immune system or live vaccines. Hydroxychloroquine is a 4-aminoquinoline with immunosuppressive, antiautophagy, and antimalarial activities.
