Ketisal (Ketotifen Hydrogen Fumarate)

Ketotifen hydrogen fumarate works by stabilizing mast cells, which blocks the release of histamine and other inflammatory mediators. It also blocks H1 histamine receptors in ocular tissues, reducing vasodilation and nerve activation that cause allergy symptoms.

The dosing regimen for Ketisal is determined by the prescribing clinician based on the severity of the allergic eye condition, patient age, and response to therapy. Patients should follow the specific instructions provided by their eye care professional.

Safety data for ketotifen hydrogen fumarate in pregnancy and lactation are limited. Women who are pregnant, planning to become pregnant, or breastfeeding should discuss potential risks and benefits with their healthcare provider before using Ketisal.

To order Ketisal, 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.

Ketisal combines antihistamine activity with mast‑cell stabilization, offering both immediate symptom relief and longer‑term control of allergic inflammation. Compared with pure antihistamine drops, Ketisal may provide more sustained protection against recurrent allergen exposure.

Ketisal should be stored at temperatures below 25 °C in its original packaging. Keep the bottle tightly closed, protect it from moisture and direct sunlight, and discard any product that appears discolored or contains particles.

Ketisal is applied as eye drops. The patient should wash their hands, tilt the head back, pull down the lower eyelid, and instill the prescribed number of drops into the conjunctival sac. The eye should be closed gently for a few seconds to allow absorption.

Serious risks, though rare, include persistent eye pain, significant visual changes, corneal ulceration, and severe allergic reactions such as swelling of the eyelids or systemic rash. Any of these symptoms require immediate medical attention.

Ketisal should be avoided in individuals with known hypersensitivity to ketotifen or any component of the formulation. Patients with active ocular infections, severe corneal disease, or those who have had recent eye surgery should consult an eye specialist before use.
