Any dangers of overdosing on allegra (fexofenadine)?
A doctor has provided 1 answer
Possibly: Allegra (fexofenadine) has been studied at very high doses with no clinically significant adverse events. However, if a high enough dose is taken there may be adverse effects. I would be most concerned about potential cardiac arrhythmias at very very high doses.
