Indications & Clinical Uses

Olynth Ha contains Xylometazoline Hydrochloride, a sympathomimetic agent that acts on nasal mucosal blood vessels to reduce congestion.

  • Common cold: Provides rapid relief of nasal blockage and improves airflow.
  • Acute sinusitis: Decreases swelling of the nasal mucosa, facilitating drainage.
  • Allergic rhinitis: Alleviates nasal congestion caused by seasonal allergens.
  • Nasal surgery recovery: Helps maintain clear nasal passages post‑operatively.

How It Works

  • Xylometazoline Hydrochloride is an alpha‑2‑adrenergic agonist that binds to presynaptic alpha‑2 receptors in the nasal mucosa, causing vasoconstriction of the sub‑mucosal blood vessels. This reduces mucosal edema and limits fluid exudation, leading to improved nasal airway patency.

Side Effects

Adverse reactions are generally mild and localized to the nasal cavity.

Common Side Effects

  • Burning or stinging sensation in the nose.
  • Nasal dryness or irritation.
  • Sneezing shortly after application.
  • Mild headache.
  • Transient epistaxis (nosebleed).

Serious or Rare Side Effects

  • Severe or persistent nosebleeds.
  • Allergic contact dermatitis affecting the nasal skin.
  • Rebound congestion after prolonged use (>5‑7 days).
  • Vision changes or ocular irritation if spray contacts the eyes.

Precautions & Warnings

When using Olynth Ha, consider the following safety measures:

  • Limit duration: Do not exceed 5‑7 consecutive days of use to avoid rebound congestion.
  • Pre‑existing conditions: Use cautiously in patients with hypertension, coronary artery disease, diabetes mellitus, or thyroid disorders.
  • Pediatric use: Follow prescriber guidance for children under 12 years of age.
  • Pregnancy & lactation: Use only if clearly needed and prescribed.
  • Drug interactions: Review concomitant nasal or systemic decongestants.
  • Store at ambient temperature: keep in original packaging, protect from moisture and direct sunlight.

Avoid Interactions

Xylometazoline may interact with other agents that affect vascular tone or adrenergic pathways.

Major Interactions (Avoid)

  • Monoamine oxidase inhibitors (MAOIs): increased risk of hypertensive episodes.
  • Systemic sympathomimetic decongestants (oral pseudoephedrine): additive vasoconstriction.

Moderate Interactions (Monitor Closely)

  • Antihypertensive medications: possible reduction in blood pressure‑lowering effect.
  • Beta‑blockers: may blunt the nasal decongestant response.
  • Topical ophthalmic vasoconstrictors: risk of ocular irritation if spray contacts eyes.

Frequently Asked Questions

Olynth Ha is a nasal spray that contains Xylometazoline Hydrochloride, a decongestant used to relieve nasal blockage caused by the common cold, acute sinusitis, allergic rhinitis and short‑term post‑surgical congestion.

Xylometazoline Hydrochloride acts as an alpha‑2‑adrenergic agonist. By stimulating presynaptic alpha‑2 receptors in the nasal mucosa it causes vasoconstriction of sub‑mucosal vessels, reducing swelling and fluid leakage, which opens the nasal airway.

The appropriate dose of Olynth Ha is determined by a qualified healthcare professional based on the patient’s age, condition and response. Prescribers typically advise one or two sprays per nostril, not to exceed the recommended treatment duration.

Safety data are limited, so Olynth Ha should only be used during pregnancy or lactation if the potential benefit outweighs any risk and it is prescribed by a healthcare provider. Consultation with a physician is essential.

To order, submit an enquiry on the Olynth Ha 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 required import documentation.

Olynth Ha’s active ingredient, Xylometazoline, provides rapid vasoconstriction similar to oxymetazoline or phenylephrine but is often preferred for its longer duration of action and lower incidence of systemic side effects when used as directed.

Store the spray at ambient temperature, ideally below 25 °C, in its original container. Protect it from moisture, extreme heat and direct sunlight to maintain potency.

The spray is applied intranasally. The patient gently tilts the head forward, inserts the nozzle into one nostril, and delivers the prescribed number of sprays while breathing in gently. The process is repeated for the other nostril if required.

Serious risks include severe or persistent nosebleeds, allergic reactions such as contact dermatitis, and rebound congestion if the product is used for more than the recommended 5‑7 days.

Individuals with known hypersensitivity to Xylometazinal or any formulation component, patients with severe uncontrolled hypertension, and those using mono‑amine oxidase inhibitors should avoid Olynth Ha unless directed by a physician.
