Are there any over-the-counter allergy medications that do not cause drowsiness?
There are indeed some over-the-counter allergy medications that do not cause drowsiness, however, most traditional allergy medications do. Drowsiness is a common side-effect among most anti-histamines and caution should be used if taking them during the day. However, Claritin® (loratadine) and Allegra® (fexofenadine) are non-drowsy formulations and, therefore, recommended for such use.
