I have a dust allergy and take Levocet M. Why do I still have a blocked nose and severe throat pain in the morning?
Even if you take Levocet M, a blocked nose and severe throat pain in the morning can still happen due to night-time dust exposure, post-nasal drip, dry air, or acid reflux. Allergies can cause mucus to collect while you sleep, leading to throat irritation on waking. Try keeping your room dust-free, using steam inhalation, warm salt-water gargles, and staying hydrated. If this keeps happening, a doctor may add a nasal spray or adjust your treatment.
