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.

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.
