US CDC Extends Malaria Treatment From Three to Five Days

The United States Centers for Disease Control and Prevention (CDC) has extended its recommended treatment duration for uncomplicated Plasmodium falciparum malaria from three days to five days when using artemether-lumefantrine.

The updated guidance recommends a 10-dose regimen, with the medicine taken twice daily for five days. The CDC said the change is aimed at reducing treatment failures, particularly late recurrences of malaria.

The recommendation followed a review of malaria treatment failures among international travellers and other patients treated in the United States. The findings were published on August 19 in Clinical Infectious Diseases in a study titled “Extending the Duration of Artemether-Lumefantrine Treatment for Uncomplicated Plasmodium falciparum Malaria.”

The researchers found evidence that a longer treatment course increases exposure to lumefantrine and could reduce the risk of treatment failure. The extended regimen was also considered safe and well tolerated in the clinical studies reviewed.

The CDC’s updated recommendation does not mean Nigerians should automatically extend their malaria medication from three to five days.

The change is specific to US treatment guidance. Artemether-lumefantrine remains a recommended treatment for uncomplicated P. falciparum malaria globally, while treatment guidelines can differ between countries based on local malaria patterns, drug effectiveness and national policies.

The key message for Nigerians is to get malaria confirmed through appropriate testing and follow the treatment prescribed by a qualified healthcare professional rather than changing the duration or dosage of medication based on the US announcement.

The CDC also advises that artemether-lumefantrine should be taken with fatty food or a milky drink to improve absorption.

The new US guidance highlights the continuing need to monitor malaria treatment effectiveness and drug resistance, particularly as researchers call for more data from malaria-endemic countries.
