Nearly 600,000 inhalers have been recalled because of a "defective delivery system," according to the FDA.
The recall affects prescription-only inhalers produced by GlaxoSmithKline that were distributed nationwide. They initiated a voluntary recall of the product on April 4th.
Three lots of Ventolin HFA 200D inhalers are impacted; lot numbers 6ZP9848, 6ZP0003 and 6ZP9944.
