Frequently asked questions

What is Levoreact used for?+
Levoreact is a nasal spray containing levocabastine hydrochloride, used to relieve symptoms of allergic rhinitis such as nasal congestion, itching, sneezing, and runny nose. It is indicated for both seasonal and perennial allergic rhinitis in patients who need rapid, localized antihistamine action.
How does levocabastine work?+
Levocabastine selectively blocks histamine H1 receptors in the nasal mucosa. By preventing histamine from binding, it stops the cascade that leads to blood vessel dilation and increased permeability, thereby reducing swelling, fluid secretion, and the sensory irritation that cause allergy symptoms.
What is the usual dose of Levoreact?+
The dosing regimen for Levoreact is determined by the prescribing healthcare professional based on the patient’s age, severity of symptoms, and clinical response. Patients should follow the prescriber’s instructions and the product label for the number of sprays per nostril and frequency of use.
Is Levoreact safe during pregnancy or breastfeeding?+
Safety data for levocabastine during 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 Levoreact.
How do I order Levoreact from GNH USA?+
To order Levoreact, submit an enquiry on the product page at gnh-usa.com, specifying the required quantity. GNH USA supplies hospitals, pharmacies, and procurement teams worldwide, and will request trade or institutional credentials before providing pricing, availability, shipping details, and any necessary import documentation.
How does Levoreact compare with other antihistamine nasal sprays?+
Levoreact’s active ingredient, levocabastine, is a selective H1‑receptor antagonist offering rapid onset of action with minimal systemic absorption. Compared with some older antihistamine sprays, it may cause fewer sedative effects and provides targeted relief directly in the nasal passages.
How should Levoreact be stored and handled?+
Levoreact should be stored at room temperature, below 25 °C, in its original packaging. Keep the bottle tightly closed, protect it from moisture and direct sunlight, and avoid exposing it to extreme temperatures that could affect spray performance.
How is Levoreact administered?+
Levoreact is administered as a nasal spray. The patient gently shakes the bottle, inserts the tip into one nostril, and sprays the prescribed number of sprays while breathing in gently. The same procedure is repeated in the other nostril if directed by the prescriber.
What are the most serious risks associated with Levoreact?+
The most serious risks include rare but severe allergic reactions such as anaphylaxis, persistent nosebleeds, and significant nasal ulceration. Users should seek immediate medical attention if they experience swelling of the face or throat, difficulty breathing, or prolonged bleeding.
Who should not use Levoreact?+
Levoreact should not be used by individuals with known hypersensitivity to levocabastine or any other component of the formulation. It is also contraindicated in patients with severe nasal infection, trauma, or those currently taking monoamine oxidase inhibitors without medical supervision.
