How It Works

Researchers don’t know exactly how hydroxychloroquine works to treat malaria. But researchers think the drug alters the way the immune system works to treat symptoms of lupus and arthritis. Specifically, it works by disrupting cell processes at the molecular level to lessen the immune system’s response.

Because the body’s natural immune response can cause inflammation, reducing the immune response helps treat rheumatoid arthritis.

People with lupus have overactive immune systems that attack the body instead of protecting it. Because hydroxychloroquine calms the immune system, it helps control symptoms of lupus.

How to Take Plaquenil

Each Plaquenil hydroxychloroquine tablet contains 200 mg of hydroxychloroquine sulfate. Depending on the condition being treated, the dosage varies. Patients should take the recommended dose with food or milk.

Medical providers may prescribe other drugs with hydroxychloroquine, such as prednisone or other corticosteroids and salicylates (aspirin) to increase treatment effectiveness.

Dosage for Malaria Prevention and Treatment

People trying to prevent malaria should start taking HCQS two weeks prior to traveling to a country or area where malaria is present. Continue taking the drug for four weeks after leaving the area of exposure. The recommended dose is 400 mg once a week on the same day of each week.

In children, the dose is 6.5 mg per kilogram of body weight. The total dose should not exceed 400 mg.

Adults taking HCQS for uncomplicated malaria start with 800 mg. Then they take 400 mg at 6, 24 and 48 hours after the first dose. This is a total of 2,000 mg.

In children with malaria, the dose is 13 mg per kilogram of body weight, not to exceed 800 mg. Then they take 6.5 mg per kilogram, not to exceed 400 mg, at 6, 24 and 48 hours after the initial dose.

Dosage for Lupus

Adults with lupus take 200 to 400 mg as a single daily dose, or divided into two doses. The drug’s medication insert doesn’t recommend doses above 400 mg a day.
