What eye drops for allergy to choose?

The classic symptoms of allergy are inflammation of the conjunctiva, which is manifested, for example, by irritation, itching, tearing and redness of the eyes, swelling of the eyelids. Good results in pharmacological treatment are brought by the local use of eye drops. They act quickly, relieving symptoms. Drops for allergy often contain cromoglycan, which stabilizes cell membranes, which prevents the degranulation of mast cells and the release of pro-inflammatory factors. Drops will inhibit the body's response in case of contact with the allergen. However, they do not reduce symptoms when the reaction has already developed. Therefore, the use of eye drops with such an effect should be preventive in nature. e.g. Polcrom - drops with cromoglycate https://www.gdziepolek.pl/produkty/62951/polcrom-krople-do-oczu/apteki?pvid=77178#internetowe Sometimes we also meet ketotifen in the form of drops. Ketotifen is a histamine H1 receptor antagonist. It inhibits the early phase of the inflammatory response. Drops with ketotifen are used in patients from 3 years of age for 1 drop in the conjunctival sac, 2 times a day. For example, Zabak https://www.gdziepolek.pl/produkty/84968/zabak-krople-do-oczu/apteki Olopatadine also has an antihistamine effect by blocking the H1 receptor. It inhibits the early phase of the inflammatory response. In addition, it stabilizes the mast cells of the conjunctiva, belongs to the group of antihistamines of the second generation. E.g. Oftahist https://www.gdziepolek.pl/produkty/55904/oftahist-krople-do-oczu/apteki Due to the content of active substances in allergy eye drops, it is recommended to remove contact lenses before instillation and put them on after about 15 minutes.
