Nearly 600,000 inhalers were just voluntarily recalled nationwide by GlaxoSmithKline due to "defective delivery system," with a large number of units having "out of specification results for leak rate" (possible package leakage).

The FDA describes the affected inhalers [1] as prescription-only "Ventolin HFA (albuterol sulfate) Inhalation Aerosol, 90 mcg per actuation, 200 metered inhalations, net weight 18 g inhalers." The recall is classified as "Class II," which means "the products might cause a temporary health problem, or pose only a slight threat of a serious nature," the FDA reports.
