China’s recommendation to use chloroquine in treatment was quickly followed by a warning. Two days after the treatment guideline update, health authorities in Hubei province — China’s worst-hit region where the outbreak started and which accounted for majority of its over 80,000 patients — asked hospitals to closely watch for, and immediately report, any adverse side effects of chloroquine phosphate, according to a report in local media outlet The Paper. The drug is known to have short-term side effects such as nausea, diarrhoea and tinnitus while long-term use can irreversibly impair eyesight. It’s forbidden for pregnant women as it can cause congenital defects in babies.

China Health Commission revised the dosage in a February 29 notice tightening chloroquine use. The drug cannot be given to pregnant women, those with heart disease, terminal liver and renal disease, retina and hearing loss and patients on antibiotics such as azithromycin and steroid. It can now be given only to patients between 18 to 65 years of age for a seven-day treatment course.

[Dr Anthony Fauci explained] that the FDA is looking for a way to make the drug available for emergency use, but in a manner that gives the government data about whether it’s safe and effective.

On February 25, Shanghai-based The Paper reported that [a woman in Wuhan] took 1.8 grams of the drug she ordered online after suspecting she had the coronavirus. She did not, but the drug caused her to develop malignant cardiac arrhythmic, which can cause sudden death, and she was admitted to the intensive care unit.

Virus drug touted as coronavirus cure can kill in just two grams
