Better not: Nyquil has different formulations, all of them contain an antihistaminic as allegra (fexofenadine), (fexofenadine) and probably a decongestant as well like in allegra (fexofenadine) D / sudafed. Can be taken separately during the day, but not advisable. Kindly read the labels carefully and see your doctor if symptoms aren't controlled with self medicating. Good that you asked, always exercise caution with multiple medications, good luck
