Got allergies that don't seem to get better, no matter what you do? Check these four common reasons why allergies don't improve -- and what to do about it. Tightening up in these four areas may go a long way toward reducing allergy symptoms of all kinds.
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.
