Epinastine HCl
Epinastine HCl is an antihistamine used primarily in the form of ophthalmic solution to treat allergic conjunctivitis (eye allergies). It works by blocking histamine receptors, specifically H1 receptors, in the eyes and preventing the release of inflammatory chemicals that cause symptoms such as itching, redness, and swelling. Epinastine is non-sedating and provides rapid relief from allergic eye symptoms.

The usual dosage of epinastine HCl is:
- One drop in each affected eye twice daily (morning and evening).
Typical Dosing
- For allergic conjunctivitis: Administer one drop in the affected eye(s) twice daily. Continue treatment as prescribed by your healthcare provider, typically throughout the allergy season or as needed.

Who Shouldn't Take Epinastine HCl?

- Contact lens use while the eyes are red or irritated, as contact lenses can exacerbate irritation.
Advice From The Pharmacist
- Epinastine HCl eye drops should be used as directed, typically twice daily.
- Do not wear contact lenses while using the drops if your eyes are red or irritated. Remove contact lenses before applying the eye drops and wait at least 10 minutes after applying before reinserting them.
- To apply, tilt your head back, pull down the lower eyelid to form a pocket, and apply one drop into the eye. Close your eyes and press lightly on the corner of the eye to prevent the medication from draining into your tear duct.
- Wash your hands before and after use, and avoid touching the tip of the dropper to your eye or any surface to prevent contamination.
