Dentists urged to reduce prescriptions of pre-treatment antibiotics

Across America, dentists write about 10% of all antibiotic prescriptions, data show, making them the top specialty prescribers of antibiotics in the U.S. one recent year.

Patients who have taken antibiotics face an elevated risk of acquiring the diarrheal disease, and the majority of infections occur in health care facilities, research has shown.

The laundered honey may contain the toxic antibiotic chloramphenicol and other antibiotics or even be adulterated with corn or cane sugar. Schneider […]

Superbug threat increased by COVID-19

A little-reported side effect of surging COVID-19 cases is the likelihood that there will be an increasing number of people exposed to antibiotic-resistant bacteria. At least 15 percent to 20 percent of people infected with SARS-CoV-2, the coronavirus that causes COVID-19, develop a secondary bacterial infection, requiring the use of antibiotics. As a result, most […]
