NS-Aid Eye Drop contains Diclofenac 0.1% w/v, a nonsteroidal anti-inflammatory drug (NSAID) indicated for the relief of ocular inflammation and pain associated with conditions such as postoperative inflammation following cataract surgery, corneal injury, and allergic conjunctivitis. Diclofenac acts by inhibiting cyclooxygenase enzymes (COX-1 and COX-2), thereby reducing the synthesis of prostaglandins, which are mediators of inflammation and pain. NS-Aid Eye Drop is administered topically to the affected eye(s), providing targeted anti-inflammatory effects while minimizing systemic exposure. It is particularly useful in reducing ocular pain, photophobia, and swelling, facilitating faster recovery and improved patient comfort. The formulation is preservative-free or contains minimal preservatives to reduce the risk of ocular irritation. NS-Aid Eye Drop should be used with caution in patients with known hypersensitivity to diclofenac or other NSAIDs. It is contraindicated in patients with active corneal infections or those with a history of corneal epithelial breakdown. Common adverse effects may include transient burning or stinging upon instillation, blurred vision, or mild eye irritation. Patients should avoid contact lens use during treatment unless otherwise advised by a healthcare professional. NS-Aid Eye Drop should be used under medical supervision, with dosing and duration tailored to the specific clinical condition.
