Sinusitis

Sinusitis is a generally self-limiting condition that has an average duration of 2½ weeks.
In suspected cases of sinusitis local measures should be advised in the first instance.
Antibiotic therapy (phenoxymethylpenicillin or doxycycline) should only be used for persistent symptoms and/or purulent discharge lasting at least seven days or if symptoms are severe.
Before prescribing antibiotics, refer to the BNF or BNFC for drug interactions.
Advise patients to space out doses as much as possible throughout the day.

N.B. Ephedrine nasal drops are no longer available to prescribe.
