Can I take Allegra M only when needed for my allergies and mucus dripping down the back of my throat, or do I need to take it for a specific number of days in a row?
Allegra M contains fexofenadine and montelukast. Unlike simple allergy medications, Allegra M works much better when taken consistently every day for a specific course, rather than just on-and-off. This is because the montelukast component needs time to build up in your system to successfully block the allergic responses causing your post-nasal drip. To get the most effective and lasting relief, please take it daily for the duration recommended by your doctor.
