2. WHAT IS POST NASAL DRIP?
• Post-nasal drip (PND) occurs when excessive mucus is produced
by the nasal mucosa. The excess mucus accumulates in the back
of the nose, and eventually in the throat once it drips down the back
of the throat.

4. CAUSES OF POST NASAL DRIP
• Rhinitis

5. • Sinusitis

6. • Acute sinusitis is inflammation of the sinuses (cavities within the
facial bones that surround your nose) usually due to a viral or
bacterial infection. Chronic rhinosinusitis is when there is ongoing
inflammation of the lining of the nose and sinuses, with symptoms
lasting longer than 12 weeks. Some people with chronic
rhinosinusitis develop nasal polyps – benign (non-cancerous)
growths that grow from the lining of the nose or sinuses.

7. • GERD

8. SYMPTOMS
• Postnasal drip makes you feel like you constantly want to clear your
throat.
• It also can trigger a cough, which often gets worse at night. In fact,
postnasal drip is one of the most common causes of a cough that just
won’t go away.
• Too much mucus may also make you feel hoarse and give you a sore,
scratchy throat.

9. SYMPTOMS
• If the mucus plugs up your Eustachian tube, which connects your throat
to your middle ear, you could get a painful ear infection.
• You could also get a sinus infection if those passages are clogged.

10. DIAGNOSIS
• Allergy testing if hay fever is considered to be causing your
symptoms and you do not know what you are allergic to. This may
involve skin prick tests or allergy blood tests.
• Other tests that may be suggested include a chest X-ray, lung
function tests and blood tests such a full blood count. A CT scan of
the nose and sinuses is occasionally recommended to confirm a
diagnosis of sinusitis.

14. TREATMENTS
• Non-drowsy antihistamines like loratadine-pseudoephedrine (Claritin) can work to
get rid of postnasal drip. However, these are more effective after you take them
for several days.
• Saline nasal sprays can help moisten your nasal passages and reduce symptoms
of postnasal drip. If you have continual problems with postnasal drip, your doctor
may prescribe a cortisone steroid nasal spray. Sinus irrigation tools like neti
pots or sinus rinses like those from NeilMed can also flush out excess mucus
