Should Allegra be taken at night or morning?

Allegra (fexofenadine) can be taken at either morning or night, but it is generally recommended to take it in the morning for best results, especially for daytime allergy relief. Since it is a non-drowsy antihistamine, taking it in the morning helps avoid potential drowsiness during daily activities. However, if you find it makes you sleepy, taking it at night may be preferable. Always consult your healthcare provider for personalized advice.
