When you come into contact with these allergens, your immune system thinks it is under attack and releases a chemical called histamine, which is to blame for those oh-so-familiar symptoms.
Under attack, that's how! One day you're fine, the next you're sneezing, your eyes are sore and watery, and your throat's itchy. You might also get headaches, a stuffy nose or blocked sinuses. Some people even lose their sense of smell or taste. But it's not all bad news - you can fight back with the right weapons. In treatments containing acrivastine, the acrivastine gets to work in 15 minutes to bring effective, long-lasting relief from all the symptoms.
There are also top tips for dealing with allergies, helping you carry on as normal all year round.
It's time to reclaim the summer!
