I accidentally took 2 Allegra-D; [email protected] 10pm and 1 @ 6:30am today. Should I worry? Just feeling a little woozy, but otherwise ok.

Not to worry. The dose and timing of Allegra-D is not concerning. Be careful with the decongestant part as this can cause issues with high blood pressure and elevated heart rate, especially if you already suffer from underlying cardiovascular conditions.
