Hydroxychloroquine Sulfate Information
(hye drox ee klor' oh kwin)Hydroxychloroquine is currently being studied for the treatment and prevention of coronavirus disease 2019 (COVID-19). Only limited clinical trial information is available at this time to support the use of hydroxychloroquine for the treatment or prevention of COVID-19. Several hydroxychloroquine clinical studies are in progress in people with COVID-19 in China and other countries. However, more information is needed to know how well hydroxychloroquine works for the treatment or prevention of COVID-19. There also are concerns about the possible side effects and drug interactions that may occur from hydroxychloroquine. Of note, the FDA has approved an Emergency Use Authorization (EUA) to allow hydroxychloroquine to treat adults and adolescents who weigh at least 110 pounds (50 kg) and who are hospitalized with COVID-19, but who are unable to participate in a clinical study. Hydroxychloroquine should ONLY be taken under the direction of a doctor.
Before taking hydroxychloroquine,
- tell your doctor and pharmacist if you are allergic to hydroxychloroquine, chloroquine, primaquine, quinine, or any other drugs.
- tell your doctor and pharmacist what prescription and nonprescription drugs, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention acetaminophen (Tylenol, others); azithromycin (Zithromax); cimetidine (Tagamet); cyclosporine (Gengraf, Neoral, Sandimmune); digoxin (Lanoxin), insulin and oral medication for diabetes; medications for seizures such as carbamazepine (Carbatrol, Epitol, Equetro, Tegretol, Teril), phenytoin (Dilantin, Phenytek), or valproic acid (Depakene); certain medications for irregular heartbeat such as amiodarone (Pacerone); methotrexate (Trexall, Xatmep); moxifloxacin (Avelox); praziquantel (Biltricide); and tamoxifen (Nolvadex). Your doctor may need to change the doses of your medications or monitor you carefully for side effects. Many other medications may also interact with hydroxychloroquine, so be sure to tell your doctor about all the medications you are taking, even those that do not appear on this list.
- if you are taking antacids, take them 4 hours before or 4 hours after hydroxychloroquine. If you are taking ampicillin, take it at least 2 hours before or 2 hours after hydroxychloroquine.
- tell your doctor if you have or have ever had liver disease, heart disease, a prolonged QT interval (a rare heart problem that may cause irregular heartbeat, fainting, or sudden death), an irregular heartbeat, a low level of magnesium or potassium in your blood, psoriasis, porphyria or other blood disorders, G-6-PD deficiency (an inherited blood disease), dermatitis (skin inflammations), seizures, vision problems, diabetes, kidney problems, or if you drink large amounts of alcohol.
