Hayfever can start before summer arrives and may continue well into autumn depending on grass, tree and weed pollen levels.
Antihistamines, nasal sprays and eye drops work best when they are matched to your symptoms and started early enough.
If you need treatment every day for weeks, ask us to check that you are using the right product in the right way.
Wheezing, shortness of breath, facial pain, fever or symptoms on one side only should be assessed by a healthcare professional.
