More than 500,000 asthma inhalers recalled

More than 500,000 asthma inhalers have been recalled nationwide.

GlaxoSmithKline has recalled the inhalers for a defective delivery system.

The inhalers were recalled on March 22 and classified as a Class II recall. According to the FDA, this means the "product may cause temporary or medically reversible adverse health consequences or where the probability of serious adverse health consequences is remote."

The FDA says that some inhalers are "out of specification results for leak rate." They were made at a GSK plant in Zebulon, North Carolina.

The lot numbers involved in the recall include lot number: 6ZP9848, expiration date 03/18 and lot numbers: 6ZP0003, 6ZP9944, expiration date 04/18.
