Acetazolamide and nifedpine are commonly used to treat respiratory symptoms in patients suffering from high-altitude pulmonary edema when fluid begins to accumulate in the lungs. A Brooklyn doctor has suggested acetazolamide would be worth examining to see if it could treat similar lung problems observed in many COVID-19 patients.
A Seattle doctor who specialize in pulmonary diseases disagrees, warning against any "false equation" of the lung problems. Using acetazolamide for COVID patients "is just wrong," he has said. High-altitude sickness and COVID are "fundamentally different from each other." Medications used to treat altitude sickness could have dangerous consequences in COVID-19 patients, he warns.
