The best way to protect yourself from hay fever is to avoid exposure to pollen. For many people, it is very difficult to avoid pollen exposure, especially in the summer when they spend more time outdoors. If you suspect you have been exposed to pollen and experience allergy symptoms, antihistamines, such as Zyrtec, can help alleviate the symptoms. Some people even use Zyrtec ( http://www.samrx.com/buy-generic-zyrtec.aspx ) as a preventive measure during summers to protect themselves from catching hay fever.
