Xolair (Asthma Drug): FDA Demands Black Box Warning

The asthma drug Xolair should carry the strongest warning possible-- a black box warning - about a reaction known as anaphylaxis, according to the FDA. According to the FDA, anaphylaxis -- a severe allergic reaction -- occurs in about one in a thousand patients taking the medication.

It can lead to breathing problems, fainting and hives no matter what dose was given, the agency warned. Doctors and patients should be prepared to treat the reaction, which may occur as late as 24 hours after patients take Xolair.
