Summer is ending, you’re heading into fall. But you’re still sneezing and sniffling all day and into the night. What’s going on?
Odds are you’re among the 10% to 30% of Americans who suffer from hay fever, or allergic rhinitis. And most cases of hay fever are caused by an allergy to fall pollen from plants belonging to the genus Ambrosia -- more commonly known as ragweed.
If you have itchy, watery eyes, antihistamine eyedrops may make you feel better. These medicines block histamine buildup in the body. Histamine is a chemical made by your immune system when you come in contact with an allergy trigger. It causes many of your allergy symptoms.
Antihistamine eyedrops are usually recommended as the first treatment for eye allergies after you have tried non-drug methods at home.
Antihistamine eyedrops can quickly relieve eye allergy symptoms. But relief may only last for a few hours. You may need to use the drops several times a day.
