What Levocabastine is used for

Levocabastine is an anti-allergy eye drop, specifically a topical antihistamine, prescribed to relieve symptoms associated with certain eye conditions. It is primarily used for:

• Seasonal allergic conjunctivitis

Seasonal allergic conjunctivitis is a common eye allergy that occurs during specific times of the year, often triggered by allergens like pollen. Symptoms can include itchy, watery, red eyes, and a gritty sensation.

How it works

Levocabastine works as a fast-acting topical H1-antihistamine. When you have an allergic reaction, your body releases a substance called histamine. Histamine is responsible for many of the uncomfortable symptoms you experience, such as itching, redness, and watery eyes. Levocabastine blocks the action of histamine at the H1 receptors in your eyes. By doing this, it helps to reduce and relieve the allergic symptoms, providing comfort and relief from irritation.

How it’s used

Levocabastine eye drops are a prescription medicine and should only be used as directed by a qualified ophthalmologist. It is important to follow their instructions carefully to ensure the medicine is effective and safe for you.

The typical dosing for Levocabastine eye drops is:

• 1 drop twice a day

Before each use, it is crucial to shake the bottle well. This is because Levocabastine is a suspension, meaning the medicine particles are suspended in a liquid, and shaking ensures the medicine is evenly distributed for the correct dose.

Always wash your hands thoroughly before handling eye drops. Tilt your head back, pull down your lower eyelid to create a small pocket, and gently squeeze the bottle to instil one drop into the eye. Try not to touch the tip of the dropper to your eye or any other surface to prevent contamination. Close your eye gently for a moment to allow the medicine to spread. If you are using other eye drops, wait at least 5-10 minutes between different medications.

Always follow your ophthalmologist’s exact instructions.

Precautions & side effects

When using Levocabastine eye drops, it is important to be aware of certain precautions to ensure safe and effective treatment:

• Shake Well Before Use: As Levocabastine is a suspension, it is crucial to shake the bottle well before each use to ensure the medicine is evenly mixed and you receive the correct dose.
• Prescription Medicine: This is a prescription eye medicine. Use it only as directed by a qualified ophthalmologist. Do not self-medicate or reuse an old prescription.
• General Eye Drop Hygiene: Always wash your hands thoroughly before and after applying eye drops. Avoid touching the tip of the dropper to your eye, eyelid, or any other surface to prevent contamination.
• Storage: Store the eye drops as instructed by your ophthalmologist or the package insert, typically in a cool, dry place away from direct sunlight.
• Disposal: Discard the bottle after the recommended period (usually 28 days after opening, even if there is medicine left) to prevent infection.
• Not Routinely Available in India: Please note that Levocabastine is not currently approved or routinely available in India. It is included here for reference. If you are experiencing symptoms of allergic conjunctivitis, please consult your ophthalmologist to discuss approved and available alternatives that are suitable for your condition.

While Levocabastine is considered a legacy but effective treatment, always discuss any concerns or side effects with your ophthalmologist. They are the best resource for personalized medical advice.

Understanding Allergic Conjunctivitis

Allergic conjunctivitis is a common condition where the conjunctiva – the clear membrane that covers the white part of your eye and lines the inside of your eyelids – becomes inflamed due to an allergic reaction. This is often triggered by allergens like pollen, dust mites, pet dander, or mould spores. When these allergens come into contact with your eyes, your immune system overreacts, releasing substances like histamine. This release of histamine leads to the characteristic symptoms of allergic conjunctivitis.

The symptoms can be quite uncomfortable and include:

• Itching: This is often the most prominent and bothersome symptom.
• Redness: Your eyes may appear bloodshot due to dilated blood vessels.
• Watering: Excessive tear production is common as your eyes try to flush out the allergens.
• Swelling: The eyelids or the conjunctiva itself can become swollen.
• Burning or Gritty Sensation: You might feel like something is in your eye.
• Light Sensitivity: Some people experience discomfort in bright light.

Seasonal allergic conjunctivitis, as the name suggests, occurs during specific seasons, typically spring and summer, when pollen counts are high. Perennial allergic conjunctivitis, on the other hand, can occur year-round and is often triggered by indoor allergens. While uncomfortable, allergic conjunctivitis is generally not a serious condition and does not typically cause long-term damage to your vision. However, persistent or severe symptoms should always be evaluated by an ophthalmologist to rule out other conditions and ensure appropriate management.

Correct Application of Eye Drops

Using eye drops correctly is essential for their effectiveness and to prevent contamination. Here’s a step-by-step guide:

1. Wash Your Hands: Always start by washing your hands thoroughly with soap and water. This is crucial to prevent introducing germs into your eyes.
2. Prepare the Bottle: If your eye drops are a suspension (like Levocabastine), shake the bottle well before each use to ensure the medicine is evenly mixed.
3. Remove the Cap: Carefully twist off the cap, being careful not to touch the inside of the cap or the dropper tip.
4. Position Yourself: You can either lie down or sit with your head tilted back. Gently pull down your lower eyelid with one finger to create a small pocket.
5. Instil the Drop: Hold the dropper bottle upside down with your other hand, positioning it directly over your eye. Look upwards, and gently squeeze the bottle to release a single drop into the pocket you created. Try your best not to let the tip of the dropper touch your eye, eyelid, or eyelashes, as this can contaminate the medicine.
6. Close Your Eye: Gently close your eye for a minute or two. Avoid blinking excessively or squeezing your eyes shut tightly, as this can push the medicine out. You can also gently press your finger to the inner corner of your eye (near your nose) for a minute to help prevent the medicine from draining away too quickly.
7. Wipe Excess: If any medicine spills onto your cheek, gently wipe it away with a clean tissue.
8. Replace the Cap: Put the cap back on the bottle immediately and securely.
9. Wash Hands Again: Wash your hands again to remove any medicine residue.

If you need to use more than one type of eye drop, wait at least 5 to 10 minutes between different medications to allow each drop to be absorbed properly.

General Eye Care, Hygiene, and When to Seek Help

Maintaining good eye hygiene is vital, especially when dealing with eye conditions. Always use clean hands when touching your eyes or applying medication. Avoid rubbing your eyes, as this can worsen irritation and potentially introduce more allergens or germs. If you wear contact lenses, your ophthalmologist will advise you on when it is safe to wear them while using eye drops for allergic conjunctivitis. Often, it’s recommended to avoid contact lenses during an allergic flare-up or to remove them before instilling eye drops and wait at least 15 minutes before reinserting them.

Proper storage of your eye drops is also important. Keep them in a cool, dry place, away from direct sunlight and out of reach of children. Always check the expiry date on the bottle and discard the medicine after the recommended period once opened, even if there is still liquid left. Typically, eye drops should be discarded 28 days after opening to prevent bacterial contamination.

While allergic conjunctivitis is usually manageable, it’s important to know when to seek professional medical help. Consult your ophthalmologist if:

• Your symptoms worsen or do not improve after a few days of using the prescribed medication.
• You experience severe eye pain, sudden vision changes, or extreme sensitivity to light.
• You notice pus or thick discharge from your eye, which could indicate an infection.
• Your eyes become very red and painful, or you develop blisters around your eyes.
• You suspect a foreign object is in your eye.

Remember, this information is for general education. Always follow the specific advice and instructions provided by your qualified ophthalmologist, as they can provide a diagnosis and treatment plan tailored to your individual needs. Do not self-medicate or use old prescriptions without consulting your doctor.
