Frequently asked questions

What conditions is Ketotifen Stada used for?+
Ketotifen Stada is used to manage allergic rhinitis, allergic conjunctivitis, and to provide prophylactic treatment for bronchial asthma. It helps relieve nasal and ocular allergy symptoms and reduces the frequency of asthma attacks by stabilizing mast cells and blocking histamine receptors.
How does ketotifen work in the body?+
Ketotifen works by stabilizing mast cells, preventing them from releasing histamine and other inflammatory mediators. It also selectively blocks H1‑histamine receptors, which reduces the body’s response to any histamine that is present, thereby alleviating allergic symptoms and supporting asthma prevention.
What is the usual dose of Ketotifen Stada?+
The appropriate dose of Ketotifen Stada is determined by a qualified prescriber based on the patient’s age, condition severity, and response to therapy. Dosage instructions are provided on the prescription label and should be followed exactly as directed by the healthcare professional.

Safety of Ketotifen Stada in pregnancy or while breastfeeding has not been definitively established. Women who are pregnant, planning to become pregnant, or nursing should discuss potential risks and benefits with their healthcare provider before using this medication.
How do I order Ketotifen Stada from GNH USA?+
To order Ketotifen Stada, submit an enquiry on the product page at gnh-usa.com, specifying the required quantity. GNH USA supplies hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.
How does Ketotifen compare with other antihistamines?+
Ketotifen combines mast‑cell stabilization with H1‑receptor antagonism, offering both preventive and symptomatic relief. Unlike many first‑generation antihistamines, it has a longer duration of action and is also used for asthma prophylaxis, making it a versatile option for patients with both allergic and asthmatic conditions.
What are the storage and handling requirements for Ketotifen Stada?+
Ketotifen Stada should be stored at ambient temperature, preferably below 25 °C. Keep the tablets in their original container, protect them from moisture and direct light, and ensure the packaging remains tightly closed to maintain product stability.

Ketotifen Stada is taken orally, usually with a glass of water. The tablet should be swallowed whole and not chewed or crushed unless otherwise directed by a healthcare professional. Follow the prescribing information for timing relative to meals.
What are the most serious risks associated with Ketotifen Stada?+
Serious risks, though rare, include severe allergic reactions such as anaphylaxis, cardiac arrhythmias, and significant liver enzyme elevations. Patients should seek immediate medical attention if they experience symptoms like difficulty breathing, swelling of the face or throat, irregular heartbeat, or jaundice.
Who should not use Ketotifen Stada?+
Ketotifen Stada should be avoided in individuals with known hypersensitivity to ketotifen or any of its excipients. Caution is also advised for patients with severe liver impairment, uncontrolled cardiac conditions, or those taking medications that may cause dangerous interactions, unless supervised by a physician.
