What is Ketotifen?
Ketotifen, the active ingredient in Ketotifen Unit Dose Stulln, is an antihistamine (H1 receptor antagonist) and mast cell stabilizer presented as an ocular unit‑dose formulation for eye‑drop use. It is employed to relieve symptoms of allergic conjunctivitis, seasonal allergic eye disease and vernal keratoconjunctivitis in patients of all ages. GNH USA supplies Ketotifen Unit Dose Stulln as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.
What is Ketotifen used for?
Ketotifen is an ocular antihistamine that targets allergic inflammation of the eye.
Allergic conjunctivitis: reduces itching, redness and tearing associated with allergic eye reactions. Seasonal allergic eye disease: alleviates symptoms during pollen or allergen exposure periods. Vernal keratoconjunctivitis: controls chronic ocular inflammation and helps prevent flare‑ups.
What are the side effects of Ketotifen?
Ketotifen may cause ocular and systemic reactions, most of which are mild and transient.
Common Side Effects: - Eye irritation or burning sensation - Stinging upon instillation - Transient blurred vision - Mild headache - Temporary hyperemia (redness) of the conjunctiva - Mild dryness of the eye
Serious or Rare Side Effects: - Severe allergic reaction (anaphylaxis) with swelling or difficulty breathing - Corneal ulceration or persistent epithelial defect - Persistent eye pain or photophobia - Sudden loss of vision - Severe dermatitis or skin rash around the eye - Significant intra‑ocular pressure increase
What precautions apply to Ketotifen?
Before using Ketotifen Unit Dose Stulln, consider the following safety measures.
Assess patient history: verify no known hypersensitivity to ketotifen or other antihistamines. Avoid use in active eye infection: postpone until infection is resolved. Monitor contact lens wearers: advise removal of lenses before instillation and waiting period before reinsertion. Pregnancy and lactation: use only if the prescriber deems benefits outweigh potential risks. Store at room temperature: keep in the original container, protect from moisture and light.
What does Ketotifen interact with?
Ketotifen may interact with other medications; review patient medication list.
Major Interactions (Avoid): - Concurrent systemic antihistamines: may increase sedation or anticholinergic load. - Use with ocular corticosteroids: can mask signs of worsening inflammation.
Moderate Interactions (Monitor Closely): - Co‑administration with other ocular antihistamines: may heighten ocular irritation. - Use with contact lens solutions containing preservatives: risk of additive eye discomfort. - Systemic MAO inhibitors: potential additive antihistaminic effects, monitor for excessive drowsiness.
