Olynth Ha (Xylometazoline Hydrochloride)

Xylometazoline Hydrochloride acts on the nasal mucosa to reduce swelling and improve airflow.

• Common cold: alleviates nasal blockage and improves breathing.
• Acute sinusitis: reduces mucosal edema, helping sinus drainage.
• Allergic rhinitis: decreases nasal congestion caused by allergen exposure.
• Nasal polyposis (post‑surgical): supports decongestion after surgical intervention.
• Upper respiratory tract infections: eases congestion symptoms during viral infections.

• Xylometazoline Hydrochloride is a selective alpha‑2 adrenergic agonist that stimulates receptors on the smooth muscle of nasal blood vessels. Activation causes vasoconstriction, which reduces vascular engorgement and limits plasma exudation, leading to decreased mucosal swelling and improved nasal airway patency.

Adverse reactions are generally mild and related to local irritation of the nasal mucosa.

Common Side Effects

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

Serious or Rare Side Effects

• Persistent nasal irritation or ulceration.
• Severe epistaxis requiring medical attention.
• Allergic contact dermatitis of the nasal skin.
• Rebound congestion (rhinitis medicamentosa) with prolonged use.
• Vision changes or ocular irritation if spray contacts the eyes.
• Systemic hypertension (very rare).

Use Olynth Ha only as directed and observe the following safety measures:

• Duration of use: Limit to no more than 3‑5 days to avoid rebound congestion.
• Age restrictions: Not recommended for children under 6 years without medical supervision.
• Pre‑existing conditions: Use cautiously in patients with hypertension, cardiovascular disease, diabetes mellitus, or thyroid disorders.
• Pregnancy and lactation: Consult a healthcare professional before use.
• Concomitant nasal medications: Avoid simultaneous use of other topical decongestants.
• Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.

Xylometazoline Hydrochloride has limited systemic absorption, but certain interactions should be considered. Major Interactions (Avoid):\n- Monoamine oxidase inhibitors (MAOIs): may potentiate vasoconstrictive effects.

• Systemic alpha‑adrenergic agonists (e.g., phenylephrine): risk of additive hypertension.

Moderate Interactions (Monitor Closely)

• Antihypertensive agents: monitor blood pressure if prolonged use occurs.
• Other intranasal decongestants: increased risk of rebound congestion.
• Topical corticosteroids: assess for local irritation when combined.
• Nasal antihistamines: monitor for additive drying effects.
• Herbal decongestants (e.g., ephedra): watch for synergistic vasoconstriction.
