Canada's chief public officer Dr. Theresa Tam is warning against using any medication, including hydroxychloroquine, to try to treat COVID-19 until scientific evidence confirms its efficacy.
The warning follows reports on social media that hydroxychloroquine can cure the respiratory illness.
Among those who have repeated the claim is U.S. President Donald Trump.
Tam says there is a large number of pre-existing medications that scientists are looking at to see whether they can treat COVID-19, but people should not take anything until the results are confirmed.
Tam adds that some of the medications have serious side effects that can actually hurt those who take them.
