Abbott Norvir Cost Chart Misrepresents Therapeutic Dose, Price – FDA Warning Letter

The pricing chart, created to explain a 2003 price increase, compares the cost of Norvir 100 mg daily to higher, labeled doses of other protease inhibitors, and implies that Norvir may be used as a monotherapy at a low dose, FDA said. The agency previously sent Abbott a letter citing Norvir promotional materials in 2001.
