What is the most appropriate intervention for a teacher with a non-productive cough worsening at night and after waking, with no other significant symptoms?

The most appropriate intervention for a teacher experiencing a non-productive cough that worsens at night and after waking, without any other significant symptoms, is to begin an antihistamine and decongestant.

This scenario suggests a possible upper respiratory issue, such as post-nasal drip or allergic rhinitis, which can often manifest as a cough that is more pronounced during the night or upon waking. The need for symptom relief in this case aligns well with the action of antihistamines, which can help reduce the mucus production and inflammation commonly associated with allergies, thus alleviating the cough. Decongestants can aid in opening the nasal passages, facilitating better airflow and reducing any related cough reflex triggered by congestion.

Utilizing a combination of antihistamines and decongestants targets the underlying issue, potentially improving the quality of sleep and overall comfort for the teacher without the need for more aggressive interventions.
