Elestat is a medication that is used for preventing itchy eyes due to eye allergies. It is a prescription eye drop that is approved for use in both adults and children as young as three years old. Although many medications are often used for "off-label" purposes, there are currently no universally accepted off-label uses for Elestat (meaning the drug should only be used to treat eye allergy symptoms).
Elestat® (epinastine ophthalmic solution) is a prescription eye medication used for preventing eye allergy symptoms. In particular, it is approved for preventing eye itching related to allergies. It belongs to a group of medications known as antihistamines.
Allergy symptoms can affect various parts of the body. Eye allergies are known medically as allergic conjunctivitis because the allergic reaction occurs in the conjunctiva (the thin layer that covers the white part of the eye and the inside of the eyelid). Symptoms of eye allergies may include:
- Itchy eyes
- Red or pink eyes
- Burning or stinging of the eyes
- Watery, teary eyes
- Puffy, swollen eyelids.
Combined with strategies to minimize a person's contact with allergens, allergy treatment can make life bearable for even the worst allergy sufferer. Treatment often includes allergy eye drops, such as Elestat. Unlike with over-the-counter decongestant eye drops, you can use Elestat long-term without the risk of actually making the redness and swelling worse after you stop the medication.
Elestat belongs to a group of allergy medications known as antihistamines. Specifically, it is an H1 receptor antagonist. This means that it blocks a specific type of histamine receptor in the body (known as H1 receptors). In addition to blocking histamine receptors, Elestat also seems to decrease the release of histamine from certain cells in the body. Since the symptoms of allergic reactions are partly caused by histamine, Elestat can help prevent or relieve allergy symptoms.
