    There are hundreds of drugs with potential retinal toxicity—so many that the National Registry of Drug-Induced Ocular Side Effects doesn’t stratify them by incidence or effect, said Frederick W. “Rick” Fraunfelder, MD, director of the Registry and associate professor of ophthalmology at Oregon Health & Science University in Portland.

    Mg 310 mg base PO once every 7 days. Alternatively, 6.5 mg/kg/dose 5 mg base/kg/dose; Max 400 mg/dose or 310 mg base/dose. Dosing should begin 2 weeks before entering and continue for 4 weeks after leaving the endemic area. The CDC suggests hydroxychloroquine as an alternative to chloroquine. It is available in 200 mg tablets of hydroxychloroquine phosphate each containing 155 mg of hydroxychloroquine. 1 Although commonly used in the treatment of rheumatologic diseases, it is a rare source of overdose in the United States. However, life-threatening symptoms can occur within an hour of ingestion. Nov 02, 2010 Hydroxychloroquine has an extremely long half life of around 32 days. This means that every 32 days, half of the previous amount of hydroxychloroquine in the body disappears. It takes around 5.5 half lives for a drug to be completely eliminated from your body meaning that you may need to wait for around 176 days.

    “It’s a pretty rare thing.” Nevertheless, he urged doctors to master the Academy’s new guidelines, because the effects from chloroquine and hydroxychloroquine, when they do occur, are severe and often irreversible. “Plaquenil toxicity isn’t even in the top 10, or the top 100” if you’re looking at incidence, he said.

    Typical daily doses of 200 to 600 mg are used for lupus and rheumatoid diseases. Hydroxychloroquine has a long terminal elimination half-life in blood 40 days, which exceed those in plasma. The oral bioavailability averages 79%. Hydroxychloroquine accumulates in several organs, especially melanin-containing retina and skin. The terminal elimination half-life of hydroxychloroquine is more than 40 days, thus blood and urine samples were collected for 5 months following each dose to characterise adequately the terminal elimination phase and obtain accurate estimates of the areas under the concentration-time curves. Plaquenil’s long half-life in the body can cause irreversible and progressive damage, Dr. Fung said. Similarly, one study reported that 16 women who’d taken hydroxychloroquine or chloroquine, or a combination of the agents, showed no improvement seven years after stopping drug therapy, and progression occurred in six of the cases. 2
