Rhinitis is inflammation of the lining of the nose.
Allergy is a common cause but it is not the only one.
Symptoms vary from the itching, sneezing and watery nasal discharge classically associated with allergy to the dry, crusting, and over-patent airway seen in atrophic rhinitis.
Allergic rhinitis is generally managed with one or more of:
- nasal decongestants
- oral antihistamines
- topical steroids
- short courses of oral steroids may occasionally be used
- topical anticholinergics
Additionally, in allergic rhinitis, an additional and very important principle, is identification and avoidance of the allergen if possible.
When the nasal discharge is profuse, blockage of the sinus ostia may occur resulting in acute bacterial sinusitis.
- a systematic review concluded (1):
- there is insufficient evidence of benefit to warrant the use of antibiotics for upper respiratory tract infections in children or adults. Antibiotics cause significant adverse effects in adults. The evidence on acute purulent rhinitis and acute clear rhinitis suggests a benefit for antibiotics for these conditions but their routine use is not recommended
- a meta-analysis concluded that (2):
- common clinical signs and symptoms cannot identify patients with rhinosinusitis for whom treatment is clearly justified.
- this meta-analysis states that antibiotics are not justified even if a patient reports symptoms for longer than 7-10 days
Management of acute rhinosinusitis (3):
- avoid antibiotics as 80% resolve in 14 days without; they only offer marginal benefit after 7days number needed to treat (NNT)15
- use adequate analgesia
- consider 7-day delayed or immediate antibiotic when purulent nasal discharge NNT8
- in persistent infection use an agent with anti-anaerobic activity eg. co-amoxiclav
- antibiotic choice - seven day course (adult)
- amoxicillin 500mg TDS 1g if severe or
- doxycycline 200mg stat then100mg OD or
- phenoxymethylpenicillin 500mg QDS
- for persistent symptoms: co-amoxiclav 625mg TDS
- note amoxicillin, phenoxymethylpenicillin or co-amoxiclav cannot be used if penicillin allergic
Note that prolonged use of nasal nasal decongestants may predispose to rhinitis medicamentosa.
- as the lining of the nose and paranasal sinuses are continuous, it is rare
for inflammation to affect one without the other. As such, the description
rhinosinusitis is often more appropriate
- postnasal drip (PND) is the drainage of secretions from the nose or
paranasal sinuses into the pharynx (4)
- often the condition is described as a chronic condition associated with repeated episodes of cold and flu
- there is accumulation of mucus in the postnasal space due to an abnormality in the mucociliary clearance (patient refers to this as ’catarrh’) (5)
- in UK both chest physician and otolaryngologists recommend the term ‘rhinosinusitis’ for post nasal drip syndrome (PNDS) (5)
- see linked item for more information re: PNDS
- postnasal drip (PND) is the drainage of secretions from the nose or paranasal sinuses into the pharynx (4)
