Hay fever is an allergic reaction to pollen, typically causing sneezing, a runny or blocked nose, itchy or watery eyes, and sometimes an itchy throat. Symptoms usually follow the pollen season — tree pollen in early spring, grass pollen through late spring and summer, and weed pollen into autumn.
Antihistamines, nasal sprays and eye drops from a pharmacy control symptoms well for most people. Keeping windows closed on high pollen days, showering and changing clothes after being outside, and wearing wraparound sunglasses can all help reduce exposure. See your GP if over-the-counter treatments aren't controlling your symptoms.
