Magnesium supplementation may reduce blood levels of chloroquine, a compound similar to hydroxychloroquine, and decrease its effectiveness.2 Until more is known, people taking hydroxychloroquine for arthritis who are also using magnesium supplements and are not experiencing relief might try avoiding the supplements or taking them at separate times.The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
