The Food and Drug Administration is reporting shortages of Zoloft and the generic version of the antidepressant as demand soars and supply chains for key ingredients are interrupted by the pandemic. .

Pfizer, the maker of Zoloft, told the FDA it has a limited supply available of the 100-count bottles of 100-milligram pills due to a “demand increase” for the drug.

Some other doses of Zoloft are still available. .
