Hayfever Symptoms & Relief

Symptoms of Hay Fever

Hay fever is caused by an allergic reaction to pollen, which can make the nose, eyes, throat and sinuses become swollen, irritated and inflamed. It’s a common allergy and will affect around one in five people at some point in their lifetime. More than ten million people are thought to suffer with hay fever in England alone.

When pollen levels increase, allergy congestion can make breathing through your nose difficult.

SUDAFED'S ®  Congestion Relief 0.1% Nasal Spray provides rapid relief from allergy congestion. Just one spray gets to work fast, and can provide lasting relief for up to 10 hours. It also moisturises the lining of the nose.
