Maresyl (Xylometazoline Hydrochloride)

Xylometazoline Hydrochloride is a selective alpha‑adrenergic agonist. By activating α1‑ and α2‑receptors on nasal mucosal vessels, it causes vasoconstriction, which reduces blood flow and edema in the nasal lining. The resulting decrease in swelling quickly eases congestion.

The appropriate dose of Maresyl is determined by a qualified healthcare professional based on the patient’s age, condition and response. Typically, adults may be instructed to spray one or two sprays per nostril every 8‑10 hours, not exceeding the maximum daily frequency advised by the prescriber.

Safety data for Xylometazoline Hydrochloride in pregnancy and lactation are limited. The product should only be used if the potential benefit justifies any possible risk to the fetus or infant, and this decision must be made by a healthcare provider.

To request Maresyl, 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.

Maresyl’s active ingredient, Xylometazoline, belongs to the imidazoline class, which typically provides rapid onset of action and a duration of several hours. Compared with phenylephrine‑based sprays, Xylometazoline often has a slightly longer effect and may be better tolerated, though individual response can vary.

Store Maresyl at room temperature, below 25 °C, in its original packaging. Protect the container from moisture, direct sunlight and extreme temperatures. Keep the product out of reach of children and do not use it after the expiration date printed on the label.

Maresyl is applied as a nasal spray. The user gently inserts the tip into each nostril, presses the pump to deliver the prescribed number of sprays, and then inhales lightly. The recommended frequency and maximum daily dose should follow the instructions given by the prescribing clinician.

Serious adverse events, though rare, include severe nasal bleeding, allergic reactions such as rash or swelling, marked hypertension, tachycardia, and rebound congestion (rhinitis medicamentosa) after prolonged use. If any of these occur, discontinue the product and seek medical attention promptly.

Maresyl should be avoided in individuals with known hypersensitivity to Xylometazoline or any excipients, in patients with severe nasal septum perforation or recent nasal surgery, and in those for whom prolonged use (beyond 3‑5 days) is contraindicated. Children under the age recommended on the label should also not use it without medical advice.
