There is no cure for hayfever, but most people can relieve their symptoms with treatment and self care including:

• Try to stay indoors when the pollen count is high
• Keep windows and doors shut as much as possible
• Wear wraparound sunglasses to stop pollen getting in eyes
• Shower and change clothes after spending time outside, to remove pollen
• Vacuum and damp dust regularly, ideally use a HEPA filter vacuum
• Use a pollen filter on car air vents
• Avoid cutting the grass 
• Don't keep fresh flowers in the home
• Avoid smoking or being around cigarette smoke as it can make symptoms worse
• Avoid drying clothes outside

If the self-care tips don't help then there are a number of over the counter treatments available including:-

• Oral antihistamines
• Intranasal antihistamines
• Intranasal corticosteroids
• Oral decongestants
