Marin County Public Health has issued an advisory to healthcare providers after regional law enforcement agencies seized a large number of counterfeit 30-milligram Percocet pills that contain fentanyl – not oxycodone hydrochloride – as their sole active ingredient. The tablets visually appear to be the pharmaceutical version—circular in shape, light blue in color, with an “M” stamped on one side and a “30” on the other side. Opioid overdoses tied to these tablets have increased since August 2019 across the region, including one case in Marin County last week. Fentanyl is 80 to 100 times more potent than morphine and 40 to 50 times more potent than heroin. Talk with your children and alert them to the current risk. Remind them to only take pharmaceutical pills prescribed by their physician, and only take them as directed. Do not share or sell medicines and do not buy medications not prescribed to them. When in doubt about a pharmaceutical, reach out and ask your doctor. Read more.
