Epina 5 mL Eye Drop is an ophthalmic antihistamine eye drop containing epinastine, a medicine used to relieve allergy symptoms in the eyes. Each drop delivers epinastine from the 5 mL bottle, which is used to help calm itchy, red, watery eyes caused by allergic conjunctivitis. It is a prescription-style eye care product that works locally in the eye rather than treating a general body allergy. Epina 5 mL Eye Drop is not for infection, and it will not replace antibiotic eye medicines when those are needed.
How it works: Epinastine works by blocking histamine, the chemical that triggers itching, redness, and tearing during an allergic reaction. As an eye drop, Epina 5 mL Eye Drop acts directly on the eye surface to reduce allergy symptoms where they start.
Epina 5 mL Eye Drop is supplied as a 5 mL eye drop bottle, which is a convenient size for people who need regular allergy-eye treatment. Since there are no other strengths or forms listed for this brand, this product is used according to the prescriber’s directions for the condition being treated. A doctor may choose this eye drop when symptoms are focused in the eyes and a local antihistamine effect is preferred over an oral allergy medicine.
Epina 5 mL Eye Drop is a 5 mL bottle, and the amount used per dose is measured as drops, not milligrams you swallow. The usual schedule for epinastine eye drops is often twice daily, but the exact number of drops and how long to use it must be decided by your doctor. Do not use more often than prescribed, because extra doses usually do not work better and may increase side effects.
Do not change your dose or stop the medicine without speaking to your doctor.
Common side effects of Epinastine may include:
