evidence: President Trump is sticking by his use of hydroxychloroquine to prevent the coronavirus despite criticism he has received from media pundits and some medical experts. [...] Hydroxychloroquine, which is available as a generic drug, is often used to treat conditions such as rheumatoid arthritis and lupus but has been touted by the president as a potential treatment for the coronavirus. However, it is recommended by medical experts not to be taken by those with underlying respiratory conditions or heart ailments, and its side effects can cause muscle weakness and heart arrhythmia. A Department of Veterans Affairs study showed that a number of veterans in a vulnerable population with underlying conditions died while taking hydroxychloroquine at a hospital, but Trump poked holes in the survey discrediting the drug.
