There has been a recall for nearly 600,000 Ventolin Asthma inhalers.
Glaxo-Smith-Kline, a British drug-making company, has received complaints about inhalers leaking.
Although the defect does not put patients in immediate danger, the company says the inhalers may deliver fewer doses than prescribed.
The inhaler recall affects three lots of Ventolin HFA 200D inhalers, including 6ZP0003,
6ZP9848, and 6ZP9944.
GSK is searching for the cause of the issue.
