Optrex Allergy (Sodium Cromoglicate)

Sodium Cromoglicate works by binding to calcium channels on mast cells in the conjunctiva. This blocks calcium influx, preventing mast‑cell degranulation and the subsequent release of histamine, leukotrienes and other inflammatory mediators that cause eye‑allergy symptoms.

The dosing regimen for Optrex Allergy is determined by the prescribing eye‑care professional. Typically, one or two drops are instilled in the affected eye(s) as directed, but the exact frequency and duration should follow the individual’s prescription.

Safety of Sodium Cromoglicate in pregnancy and lactation has not been definitively established. It should be used only if the potential benefit justifies any possible risk to the fetus or infant, and after consultation with a healthcare provider.

To order Optrex Allergy, submit an enquiry on the product page at gnhindia.com specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

Compared with antihistamine eye drops, Sodium Cromoglicate does not block histamine receptors but prevents its release, offering a prophylactic effect. It is often used when patients need a non‑steroidal option or when antihistamines alone are insufficient for symptom control.

Optrex Allergy should be stored at room temperature, away from direct sunlight and moisture. Keep the bottle tightly closed when not in use, and protect it from extreme temperatures to maintain product stability.

The product is administered as eye drops. The recommended technique is to tilt the head back slightly, pull down the lower eyelid to create a pocket, and place the prescribed number of drops into the conjunctival sac, avoiding contact with the eye or eyelashes.

Serious risks, although rare, include severe eye pain, persistent redness, corneal ulceration, vision loss, systemic allergic reactions and anaphylaxis. Any of these symptoms require immediate medical attention and discontinuation of the product.

Individuals with known hypersensitivity to Sodium Cromoglicate or any excipients in the formulation should avoid using Optrex Allergy. It is also contraindicated in patients with active ocular infections or severe corneal disease until cleared by an eye‑care professional.
