Optilast Eye Drops: Effective Relief for Hay Fever Symptoms
What is Optilast?
Optilast is an effective antihistamine eye drop designed to relieve itchy, watery eyes caused by seasonal allergic conjunctivitis (hay fever) and perennial allergic conjunctivitis. It contains the active ingredient azelastine hydrochloride, which reduces eye irritation by blocking the effects of histamine released in response to allergens like pollen, pet dander, dust, or mould.
What is Optilast Used For?
Optilast is primarily used for treating:
- Seasonal allergic conjunctivitis: Caused by outdoor allergens like pollen, with symptoms during high-pollen seasons.
- Perennial allergic conjunctivitis: Caused by year-round allergens such as dust or pet dander.
How Does Optilast Work?
Optilast’s active ingredient, azelastine hydrochloride, is a type of antihistamine that:
- Blocks histamine, the chemical released by the immune system during an allergic reaction.
- Prevents irritation, reducing symptoms such as itchiness, redness, and excessive tearing.
You can expect noticeable symptom relief within 15-30 minutes of applying the drops.
