I-Gesic Eye Drop contains Diclofenac 0.1% w/v, a nonsteroidal anti-inflammatory drug (NSAID) specifically formulated for ophthalmic use. It is indicated for the relief of ocular inflammation and pain associated with conditions such as postoperative inflammation following cataract surgery, corneal injuries, and allergic conjunctivitis. Diclofenac exerts its therapeutic effect by inhibiting cyclooxygenase enzymes (COX-1 and COX-2), thereby reducing the synthesis of prostaglandins, which are mediators of inflammation and pain. The topical application of I-Gesic Eye Drop allows for targeted anti-inflammatory action with minimal systemic absorption, enhancing safety and efficacy. It is typically administered as one or two drops into the affected eye(s) 2 to 4 times daily, as directed by a healthcare professional. Patients should avoid contact lens use during treatment unless otherwise advised. Common side effects may include transient burning or stinging upon instillation, mild ocular irritation, or dryness. Contraindications include hypersensitivity to diclofenac or any component of the formulation. Caution is advised in patients with pre-existing ocular conditions or those using other ophthalmic medications. I-Gesic Eye Drop should be stored at room temperature, protected from light, and kept out of reach of children. It is essential to adhere to prescribed dosage and duration to prevent potential adverse effects and ensure optimal therapeutic outcomes.
