Severe Asthma Attack Warnings for Serevent
The FDA recently asked the makers of Serevent Diskus, Advair Diskus, and Foradil Aeolizer to update thier labels to include risk of severe asthmatic attack. The drugs work to keep asthma episodes to a minimum with a medicine called "long-acting beta 2-adrenergic agonists" (LABA). All asthma drugs with this medicine will include this warning.
The problem is the drugs lower the frequency of asthma attacks, but actually greatly increase the severity of an attack when they occur. There is at least one death reported from the use of these drugs.
