Alcaftadine
About Alcaftadine
Alcaftadine is an ophthalmic (eye) drop used to prevent itchy eyes caused by allergic conjunctivitis. It is designed to target and relieve eye allergies triggered by pollen, dust, pet dander, and other common airborne irritants. By treating the symptoms directly at the source, it helps restore comfort to your eyes.
To get the most benefit, you should use Alcaftadine consistently at the same time each day as prescribed by your doctor. Because this medicine is applied directly to the eyes, it can be used with or without food. Making simple lifestyle adjustments, such as keeping windows closed during high-pollen seasons, can further support your eye comfort.
Most people can use these eye drops without experiencing major issues, but mild side effects like a temporary burning or stinging sensation can occur. If you notice more serious symptoms, such as severe eye pain, changes in your vision, or worsening eye redness, you should stop using the drops and consult your doctor right away.
Do not use this medicine if you are allergic to any of its ingredients. If you wear soft contact lenses, you must remove them before applying the drops, as the solution contains preservatives that can absorb into and discolour the lenses. Talk to your doctor before starting this medicine if you have an active eye infection or other eye-related health conditions.
While the active ingredients in these eye drops primarily act locally in the eye, it is still important to discuss all other medications you are using with your health provider. If you are pregnant, planning to become pregnant, or breastfeeding, consult your doctor or pharmacist to ensure these drops are safe for your specific situation.

Habit Forming
Diet & Lifestyle Advise
Managing eye allergies effectively involves both medical treatment and reducing your exposure to triggers. Consider these practical adjustments:
- Monitor pollen counts: Keep windows closed and stay indoors as much as possible on days when pollen levels are high.
- Use cool compresses: Apply a clean, cold, damp cloth over closed eyes to soothe itching and inflammation.
- Avoid rubbing your eyes: Rubbing can release more histamine, worsening the itchiness and potentially leading to corneal irritation or infection.
- Wash your face and hands: After spending time outdoors, wash your face, hands, and hair to remove trapped allergens.
- Keep indoor air clean: Use high-efficiency particulate air (HEPA) filters in your home and vacuum carpets regularly to minimise dust and pet dander.
Special Advise
Remove your contact lenses before using Alcaftadine to avoid any unpleasant side effects.
Do not put two eye drops together. Try to maintain a gap of at least 5-10 minutes between the two eye drops.
Patients Concern
Disease/Condition Glossary
Allergic conjunctivitis: Allergic conjunctivitis is a quite common eye inflammation that happens when your eyes come into contact with an allergen. Symptoms such as itching, redness of the eyes can occur because the overreacting immune system causes the body to release histamine and other active substances. As a result, the blood vessels dilate or expand, irritates the nerve endings. Allergic conjunctivitis is different from infective conjunctivitis.
