Chapter 1: Clinical Overview
You must refer to the pharmacist, if in your conversation you discover that your patient:
takes other medication, though most of the hay fever treatments do not have significant contra-indications with other medicines.
has other health conditions, or is pregnant, or breastfeeding.
has mucous that is thick and coloured, as there may be a secondary bacterial infection.
is using an unsuitable product such as a decongestant nasal spray for longer than 3 days or a decongestant eye drop for itchy, watery eyes associated with hay fever.
has been using recommended treatments but is not gaining symptomatic relief.
And refer if you are unsure whether it is an allergic reaction, like hay fever, or a viral infection, such as a cold.
