Summary
Epinastine is used to treat allergic conjunctivitis, which is an eye inflammation caused by allergies. It helps relieve symptoms like itching, redness, and swelling in the eyes. Epinastine is typically used as a complementary addition to other allergy treatments, such as oral antihistamines, to provide targeted relief for eye symptoms.
Epinastine works by blocking histamine receptors in the eyes. Histamine, which is a chemical released during allergic reactions, causes symptoms like itching and redness. By blocking these receptors, epinastine reduces these symptoms. Think of it like putting a barrier between the histamine and your eyes, preventing the allergic reaction from causing discomfort.
Epinastine is usually taken as an eye drop. The usual dose for adults is one drop in each affected eye twice daily. Use it as directed by your doctor, typically once or twice a day. Wash your hands before use, and avoid touching the dropper tip to prevent contamination.
Common side effects of epinastine include mild eye irritation, burning, or itching. These effects are usually temporary and resolve on their own. If you notice new symptoms after starting epinastine, they might be temporary or unrelated to the medication. Talk with your doctor if you have concerns.
Avoid using epinastine if you're allergic to any of its ingredients. If you experience eye irritation, redness, or swelling, stop using it and contact your doctor. If you wear contact lenses, remove them before using the drops and wait at least 10 minutes before reinserting them. Always follow your doctor's instructions.
