Nov 01, 2015 This cumulative dose is created when the common dose of 400 mg/day is used for 6.8 years. Hydroxychloroquine is metabolized and secreted by both the liver and the kidneys. Therefore, disturbed renal or hepatic function might reduce HCQ clearance and increase the propensity for toxicity. The number of reported cases of likely toxicity begins to increase sharply after approximately 5 years of use. 10 A cumulative dose of 1000 g HCQ is reached in 7 years with a typical daily dose of 400 mg, and a cumulative dose of 460 g CQ is reached in 5 years with a typical daily dose of 250 mg.

Toxicity from hydroxychloroquine may be seen in two distinct areas of the eye the cornea and the macula.
