What is Winolap Eye Drop?
Winolap Eye Drop is manufactured by Sun Pharma and contains Olopatadine HCl 0.1% as a sterile ophthalmic solution. It is a dual-action drug: it blocks H1 histamine receptors (immediate relief from itching, redness, watering) and stabilises mast cells (prevents histamine release in subsequent exposures). This dual mechanism gives both rapid symptom relief and prophylactic benefit.
How It Works
Olopatadine HCl competitively blocks the H1 histamine receptor on conjunctival nerve endings, preventing the itching and vasodilation that histamine causes. It also stabilises mast cell membranes so that subsequent allergen exposure releases less histamine. Onset is within 5–10 minutes; duration is 12–24 hours depending on formulation.
Indications
- Seasonal allergic conjunctivitis (pollen-driven, hay fever)
- Perennial allergic conjunctivitis (year-round, dust mite/pet dander)
- Vernal keratoconjunctivitis (childhood-adolescent severe allergic disease)
- Atopic keratoconjunctivitis
Dosing
1 drop in each eye twice daily. Onset within 5–10 minutes. May be used continuously through allergy season for prophylactic effect.
Side Effects
Local: mild stinging on instillation, transient blurred vision, dry sensation, mild headache, taste disturbance.
Systemic: minimal.
Warnings & Contraindications
- Hypersensitivity to Olopatadine HCl
- Pregnancy — Category B for olopatadine, generally safe; discuss
- Breastfeeding — limited data; minimal topical absorption
- Contact lens wearers — remove before instillation, re-insert after 10 minutes (preservative)
- Children — usually safe from age 3+
Storage
Store at 15–25°C. Discard 28 days after first opening.
Frequently Asked Questions
How quickly does Winolap Eye Drop work?
Itching and redness improve within 5–10 minutes of the first drop. Maximum effect at 30 minutes. Duration is 12–24 hours depending on the formulation.
Should I use Winolap Eye Drop prophylactically through allergy season?
Yes — daily use through your typical allergy season (e.g., March–June for pollen) provides ongoing mast-cell stabilisation, reducing the severity of flares.
Is Winolap Eye Drop better than oral antihistamines?
For ocular symptoms specifically, topical antihistamines work faster, more selectively, and avoid drowsiness. Oral antihistamines also work but are slower at the eye and can dry tear film. Many patients use both for nose+eye symptoms.
Can I use Winolap Eye Drop with contact lenses?
Remove lenses before instillation; reinsert after 10 minutes. The preservative can be absorbed by soft lenses and irritate.
Is Winolap Eye Drop safe in pregnancy?
Olopatadine is Category B with minimal topical absorption. Generally safe. Epinastine — discuss with prescriber. Topical absorption is much lower than oral antihistamines.
Can children use Winolap Eye Drop?
Generally safe from age 3+. Below age 3 — discuss with paediatrician.
What if symptoms don't improve?
Re-evaluate. Possibilities: more severe disease (vernal/atopic keratoconjunctivitis needing steroid pulse), wrong diagnosis (dry eye, infection), or chronic mast-cell disease.
What is dual action?
Olopatadine HCl blocks H1 histamine receptors immediately AND stabilises mast cells over hours-days. The combination gives quick relief plus prophylactic benefit when used regularly through allergy season.
Can I use Winolap Eye Drop with other allergy drops?
Yes if needed — wait 5 minutes between bottles. Most patients find Olopatadine HCl alone sufficient.
What if my eyes are also dry?
Allergy and dry eye often coexist. Add a preservative-free lubricant 4 times daily. Severe dry eye also benefits from cyclosporine.
