What Epinastine is used for

Epinastine eye drops are primarily used to treat:

Allergic conjunctivitis

Allergic conjunctivitis is a common eye condition where your eyes become inflamed due to an allergic reaction. This can happen when your eyes come into contact with allergens like pollen, dust mites, pet dander, or certain chemicals. When this occurs, your body releases substances that cause symptoms such as itching, redness, watering, and swelling of the eyes. Epinastine helps to manage these uncomfortable symptoms, providing relief and improving your comfort.

At Pristine Eye Hospitals, our ophthalmologists carefully diagnose your condition to ensure Epinastine is the right treatment for you. We understand how disruptive allergic conjunctivitis can be to your daily life, and our goal is to provide effective and safe solutions to help you see and feel better.

How it works

Epinastine works through a dual-action mechanism to combat the symptoms of allergic conjunctivitis. Firstly, it acts as an antihistamine. When your body encounters an allergen, it releases a chemical called histamine, which is responsible for many allergy symptoms like itching and redness. Epinastine blocks the action of histamine, thereby reducing these irritating symptoms.

Secondly, Epinastine is also a mast cell stabiliser. Mast cells are immune cells that release histamine and other inflammatory substances during an allergic reaction. By stabilising these mast cells, Epinastine helps to prevent the release of these chemicals in the first place, offering a more sustained relief from allergic symptoms. This dual action makes Epinastine effective in both immediate symptom relief and preventing future allergic responses.

Importantly, Epinastine is known to have a minimal drying effect on the eyes, which can be a common concern with some other anti-allergy medications. This makes it a comfortable option for many patients experiencing allergic conjunctivitis.

How it’s used

Epinastine eye drops are typically used by instilling 1 drop twice a day into the affected eye(s). It is crucial to follow your ophthalmologist’s specific instructions regarding the dosage and duration of treatment. Do not alter the dose or stop using the drops without consulting your doctor.

For proper instillation of eye drops, please follow these general steps:

Wash your hands thoroughly with soap and water before touching your eyes or the eye drop bottle.
If you wear contact lenses, remove them before applying the drops, unless your doctor advises otherwise. Wait at least 15 minutes after instilling the drops before reinserting your contact lenses.
Tilt your head back slightly and pull down your lower eyelid to create a small pocket.
Hold the dropper bottle upside down with the tip pointing towards your eye. Do not let the tip touch your eye, eyelid, or any other surface to prevent contamination.
Gently squeeze the bottle to release one drop into the pocket you created.
Close your eye gently for a minute or two, without blinking or squeezing, to allow the medicine to be absorbed.
Blot any excess liquid from your eyelid with a clean tissue.
If you need to use drops in both eyes, repeat the process for the other eye.
If you are using other eye drops, wait at least 5-10 minutes between different medications to ensure each drop is properly absorbed.
Replace the cap tightly on the bottle immediately after use.

Always use Epinastine exactly as prescribed by your ophthalmologist at Pristine Eye Hospitals to achieve the best results and ensure your eye health.

Always follow your ophthalmologist’s exact instructions.

Understanding Allergic Conjunctivitis

Allergic conjunctivitis is a common and often irritating eye condition that affects many people in India. It occurs when your eyes react to substances called allergens, which are usually harmless to most people. Common allergens include pollen from trees, grasses, and weeds, dust mites found in homes, pet dander (tiny flakes of skin from animals), and sometimes even certain cosmetics or contact lens solutions. When these allergens come into contact with your eyes, your body’s immune system overreacts, releasing chemicals like histamine. This release causes the blood vessels in your conjunctiva (the clear membrane covering the white part of your eye and the inside of your eyelids) to swell and become red, leading to the characteristic symptoms of allergic conjunctivitis.

The symptoms can range from mild to severe and often include intense itching, redness of the eyes, excessive tearing or watery eyes, a burning sensation, and sometimes swelling of the eyelids. These symptoms can be quite uncomfortable and interfere with daily activities, making it difficult to concentrate, read, or even drive. While allergic conjunctivitis is generally not a serious threat to your vision, it can significantly impact your quality of life. Identifying and avoiding your triggers is a key part of managing the condition, alongside appropriate medical treatment prescribed by an ophthalmologist. At Pristine Eye Hospitals, we help patients understand their condition and provide tailored treatment plans to bring relief and improve eye comfort.

Correct Eye Drop Instillation and Hygiene

Using eye drops correctly is vital for their effectiveness and to prevent eye infections. Many people do not realise that improper technique can reduce the medicine’s benefits or even introduce germs into the eye. Here’s a detailed guide to ensure you are instilling your eye drops safely and effectively:

Wash Your Hands Thoroughly: This is the most critical step. Always wash your hands with soap and water for at least 20 seconds before touching your eyes or the eye drop bottle. This prevents the transfer of bacteria or viruses from your hands to your eyes.
Check the Bottle: Before each use, quickly check the expiry date on the bottle. Do not use expired medication. Also, ensure the dropper tip is clean and intact.
Remove Contact Lenses (if applicable): If you wear contact lenses, remove them before applying eye drops unless your ophthalmologist has specifically advised otherwise. Some eye drops can interact with contact lens materials or cause discoloration. Wait at least 15 minutes after instilling the drops before reinserting your lenses.
Prepare for Instillation: Tilt your head back or lie down. Gently pull down your lower eyelid with one finger to create a small pocket between your eye and the eyelid.
Instil the Drop: Hold the eye drop bottle upside down with your other hand, positioning the tip directly over your eye. Be careful not to let the tip touch your eye, eyelashes, or any other surface. This is crucial to prevent contamination of the bottle’s contents. Gently squeeze the bottle to release a single drop into the pocket you created.
Close Your Eye Gently: After instilling the drop, close your eye gently for about 1 to 2 minutes. Avoid blinking or squeezing your eye tightly, as this can push the medicine out before it has a chance to be absorbed. You can also gently press your finger to the inner corner of your eye (near your nose) for a minute to help keep the drop in the eye and prevent it from draining into your tear duct.
Clean Up: Blot any excess liquid around your eye with a clean tissue. Do not rub your eye.
Replace the Cap: Immediately replace the cap on the bottle tightly to prevent contamination and keep the medicine sterile.
Multiple Drops/Eyes: If you need to use more than one drop in the same eye, or if you are using drops in both eyes, wait at least 5-10 minutes between different drops to ensure each medication is properly absorbed and doesn’t wash out the previous one.

General Advice and When to Seek Help

Maintaining good eye hygiene is paramount, especially when dealing with eye conditions. Always use fresh, clean tissues to wipe your eyes. Avoid sharing eye makeup, towels, or pillowcases, as this can spread infections or allergens. Store your eye drops as directed by your ophthalmologist or the packaging instructions, usually at room temperature and away from direct sunlight and excessive heat. Never store eye drops in the refrigerator unless specifically instructed to do so. Once opened, eye drop bottles have a limited shelf life, typically 28 days, after which they should be discarded even if there is medicine remaining. This is because the preservative in the drops becomes less effective over time, increasing the risk of bacterial contamination.

While Epinastine is generally well tolerated, it is important to be vigilant for any unusual symptoms or worsening of your condition. If your symptoms of allergic conjunctivitis do not improve after a few days of using the drops, or if they worsen, you should contact your ophthalmologist at Pristine Eye Hospitals immediately. Also, seek prompt medical attention if you experience severe eye pain, sudden vision changes, increased redness, discharge from the eye, or any signs of an allergic reaction to the drops themselves (e.g., severe itching, swelling around the eye, rash).
