Lastin is an ocular antihistamine that acts on the allergic conjunctivitis pathway to relieve eye allergy symptoms. - Allergic conjunctivitis: alleviates itching, redness, tearing and swelling of the conjunctiva. - Seasonal allergic conjunctivitis: provides rapid symptom relief during pollen or allergen exposure periods. - Perennial allergic conjunctivitis: maintains consistent control of eye‑related allergy signs with regular use.

Common Side Effects: - Eye irritation or burning sensation. - Bitter taste after instillation. - Transient headache. - Blurred vision. - Mild conjunctival redness. Serious or Rare Side Effects: - Severe allergic reaction (anaphylaxis). - Corneal ulcer or epithelial defect. - Significant increase in intra‑ocular pressure. - Vision loss. - Persistent severe eye pain.

Before using Lastin, consider the following precautions: - Assess patient history: check for hypersensitivity to azelastine or other antihistamines. - Avoid use in active eye infection: postpone treatment until infection resolves. - Monitor for ocular irritation: discontinue if severe or persistent. - Caution in patients with glaucoma: evaluate intra‑ocular pressure regularly. - Pregnancy and lactation: use only if potential benefits justify the risk. - Store at room temperature: keep in the original container, protect from light and moisture.
