This is a specific type of ingredient that is called an inflammatory agent and is contained in various eye drop products that can be found either over the counter or in prescription form. There are a large number of people that use this type of product for the relief of bothersome allergy symptoms that they may experience when they have come in contact with allergens that are known to cause the irritating feeling of burning and itchy eyes. One of the most liked advantages that is very beneficial to individuals who choose to use eye drops that contain corticosteroids is that this type of eye drops also offers them a huge amount of relief from a lessening of the swelling and irritation that often occurs when a person is experiencing symptoms that are caused by allergens. They work by decreasing the ability of the body being able to produce the histimine that is responsible for these symptoms. People with an existing eye infection should not use these eye drops. This is because when they are used in combination with anti-allergy drops used in the eyes, they can actually cause an increase in the person’s risk of obtaining an infection.
