Combination with hepatotoxic or dermatitis-causing medication should be avoided, as well as with heparin risk of hemorrhage and penicillamine. Eye Keratopathy and retinopathy may occur when large doses of chloroquine are used for long periods.

  6. Chloroquine and hydroxychloroquine can cause toxic retinopathy due to their binding of melanin in the retinal pigmented epithelium RPE as well as direct toxicity to retinal ganglion cells.

    Chloroquine and hydroxychloroquine both belong to the quinolone family and share similar clinical indications and side effects, including retinal toxicity. Chloroquine-induced retinal toxicity was first described in 1959 and the retinal toxic effects of hydroxychloroquine were later described in 1967 3, 4. In 1959, Hobbs established a definite link between long-term use of chloroquine and subsequent development of retinal pathology. In 1962, J Lawton Smith coined the term bull's eye maculopathy, regarded as the classic finding of macular toxicity. Many reports on chloroquine retinopathy exist. The usefulness of hypokalemia as an indicator in the evaluation of chloroquine toxicity was studied in a retrospective series of 191 acute chloroquine poisonings. Results indicated that the risk of severe poisoning and death are proportional to the degree of hypokalemia.
