Ketof (Ketotifen Hydrogen Fumarate)

Ketotifen works by blocking histamine H1 receptors, preventing histamine from triggering allergic symptoms. At the same time, it stabilizes mast cells, limiting the release of inflammatory mediators such as leukotrienes and cytokines, which contributes to reduced airway hyper‑responsiveness and ocular irritation.

The dosage of Ketof is determined by the prescribing clinician based on the patient’s age, severity of symptoms, and overall health status. Healthcare providers set the appropriate strength and frequency to achieve optimal therapeutic effect while minimizing adverse reactions.

Safety data for ketotifen 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 professional before starting Ketof.

To request Ketof, 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.

Ketof combines H1‑receptor antagonism with mast‑cell stabilization, offering both symptom relief and preventive benefits. Unlike many first‑generation antihistamines, it has a longer duration of action and is also used for asthma prophylaxis, making it a broader‑spectrum option for patients with multiple allergic manifestations.

Ketof should be stored at ambient temperature, preferably below 25 °C. Keep the tablets in the original packaging, protect them from moisture, excessive heat and direct sunlight to maintain potency throughout the shelf life.

Ketof is supplied as oral tablets intended for swallowing with water. The medication is taken as directed by a healthcare professional, usually once or twice daily, depending on the clinical indication and individual response.

Serious adverse events, although rare, can include severe skin reactions such as Stevens‑Johnson syndrome, anaphylaxis, liver toxicity, and cardiac arrhythmias. Patients should seek immediate medical attention if they notice rash, breathing difficulty, jaundice, or irregular heartbeats.

Ketof is contraindicated in individuals with known hypersensitivity to ketotifen or any excipients in the tablet. Caution is advised for patients with severe hepatic impairment, uncontrolled asthma, or those taking medications that may cause dangerous interactions, such as MAO inhibitors.
