There's a chance that the recalled inhalers won't administer the correct dosage of albuterol.

GlaxoSmithKline is recalling nearly 600K Ventolin inhalers for a "defective delivery system."

The inhalers recalled are Ventolin® HFA 200D with lot numbers 6ZP9848, 6ZP0003 or 6ZP9944 and expire in March or April of 2018.
