Postnasal drip treatment: options and next steps

Postnasal drip happens when mucus from the nose or sinuses reaches the back of the throat. Treatment differs when the main problem is allergic rhinitis, sinusitis, chronic sinusitis, or acid reflux. Congestion and sneezing point toward nasal inflammation, while facial pressure or reduced smell may suggest sinus involvement; throat irritation after meals can fit reflux.

A clinician may review your symptoms, medicines, allergies, and examination findings. A continuing cough should not automatically be labelled postnasal drip, particularly when it affects breathing or daily activity.

Saline spray or rinsing can help wash away irritants and loosen mucus when used as directed. Fluids, avoiding smoke, and reducing exposure to known allergens may support comfort. A pharmacist or clinician may recommend an antihistamine or nasal spray when allergy is involved.

If reflux contributes, discuss meal timing, lying down after eating, and medicines with a clinician. Sinus symptoms may need a different plan. Use nasal decongestants only as directed, because prolonged use can worsen congestion. Check interactions before adding a new medicine.

Seek a routine review for symptoms that persist, recur, disturb sleep, or do not respond to sensible self-care. Get urgent help if you have breathing difficulty, chest pain, coughing blood, confusion, swelling around an eye, severe headache, or rapid worsening.

What cause best matches my pattern of symptoms? Which treatment should I try first, for how long, and what side effects should I watch for? Does my cough or sinus pressure need a separate assessment?
