Chloroquine and Hydroxychloroquine Information for Providers and Public Health Officials

Chloroquine and Hydroxychloroquine Information for

Providers and Public Health Officials

Responding to COVID-19

The Centers for Disease Control and Prevention (CDC) has learned of two people who ingested non-pharmaceutical chloroquine phosphate, a chemical for aquarium use that is commercially available at stores and internet websites. One of the individuals died shortly after arrival at a hospital. The second individual was critically ill.

Ohio Department of Health Director Amy Acton, M.D., MPH, strongly recommends that clinicians and public health officials take the following actions:

  • Educate patients on the serious risks of misusing non-pharmaceutical chloroquine products and other aquarium use chemicals.
     
  • Counsel your patients on the importance of taking medications only as prescribed and as directed by healthcare providers.
     
  • Contact your local poison center (1-800-222-1222) to report cases and to obtain specific medical management of chloroquine and hydroxychloroquine poisoning.
     
  • Report adverse events related to non-pharmaceutical products by emailing FDA-COVID-19-Fraudulent-Products@fda.hhs.gov or calling 1-888-InfoFDA (1-888-463-6332). Report adverse events related to pharmaceuticals to the FDA MedWatch program (https://www.fda.gov/safety/medwatch-fda-safety-information-and-adverse-event-reporting-program).

Additional information:

  • Chloroquine phosphate, when used without a prescription and supervision of a healthcare provider, can cause serious health consequences, including death. Chloroquine, and the related compound hydroxychloroquine, should be used only under the supervision of a healthcare provider as prescribed medication and according to instructions provided.
     
  • In overdose situations or when otherwise used inappropriately, these medications can lead to severe toxicity, including cardiac rhythm disturbances (such as prolonged QT), severe hypokalemia, cardiovascular collapse, seizures, coma, and death.
     
  • Inappropriate uses include taking commercially available non-pharmaceutical products, taking chloroquine phosphate or hydroxychloroquine sulfate without a prescription, and taking additional doses not recommended by a healthcare provider. Chloroquine phosphate has a narrow therapeutic index — it can be toxic at levels not much higher than those prescribed — which raises the risk of inadvertent overdose.
     
  • There are no routinely available pharmaceutical products that are FDA-approved for the prevention or treatment of COVID-19.
