How does Diphenhydramine affect mucus secretion in nasal allergies, and can it effectively reduce nasal congestion and sinus pressure in allergic patients?
Diphenhydramine has minimal effect on mucus secretion. It primarily relieves allergy symptoms via antihistamine action but is not effective in reducing nasal congestion.
Diphenhydramine, primarily an antihistamine, does not significantly reduce mucus production in nasal allergies and is less effective for easing nasal congestion and sinus pressure.
