It is generally not recommended to take Allegra and Montair FX together. Montair FX already contains fexofenadine (the active ingredient in Allegra) combined with montelukast. Taking both medications at the same time would lead to an accidental double dose of fexofenadine, which can increase your risk of side effects like drowsiness, dry mouth, or headaches. To keep you safe, please consult your doctor to see which single medication or alternative treatment is best for your eczema.
