Warrick Pharmaceuticals of Niles, Ill., is recalling 190,000 prescription albuterol inhalers used to fight asthma attacks because one patient discovered the inhaler he bought was empty.
The company said a production error allowed fewer than 150 inhalers to slip through without being filled.
The recalled inhalers bear the lot number 9-BBS-525 on the box and on the cannister's label, and show an August 2001 expiration date. Pharmacies nationwide sold the inhalers from late April through September 1999 for about $18.
Patients who have a recalled inhaler can return it to the drugstore of purchase for a free replacement.
