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: decreases nasal mucosal edema, facilitating sinus drainage.
• Allergic rhinitis: reduces nasal congestion caused by seasonal or perennial allergens.
• Upper respiratory tract infections: eases congestion and pressure in the nasal passages.
• Nasal surgery recovery: helps maintain clear airways post‑operatively.

• Xylometazoline Hydrochloride is a selective alpha‑adrenergic agonist that stimulates alpha‑1 and alpha‑2 receptors in the nasal submucosal blood vessels. This stimulation causes vasoconstriction, leading to reduced blood flow, decreased mucosal edema, 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).

Serious or Rare Side Effects

• Persistent nasal irritation or ulceration.
• Severe or prolonged nosebleeds.
• Allergic contact dermatitis affecting the nasal skin.
• Hypertensive crisis in susceptible individuals.
• Rebound congestion after prolonged use (>5‑7 days).

Before using Olynth Ha, consider the following safety measures:

• Contraindication: Do not use in patients with known hypersensitivity to xylometazoline or any formulation excipients.
• Age restriction: Avoid use in children under 6 years unless specifically directed by a healthcare professional.
• Duration of use: Limit use to no more than 5‑7 consecutive days to reduce risk of rebound congestion.
• Cardiovascular caution: Use with caution in patients with hypertension or cardiovascular disease.
• Pregnancy and lactation: Consult a healthcare provider before use during pregnancy or breastfeeding.
• Store at ambient temperature: keep in the original packaging, protect from moisture and direct sunlight.

Xylometazoline Hydrochloride may interact with other medications that affect vascular tone or blood pressure.

Major Interactions (Avoid)

• Monoamine oxidase inhibitors (MAOIs): may potentiate hypertensive effects.
• Systemic decongestants (e.g., pseudoephedrine): combined vasoconstriction can increase blood pressure.

Moderate Interactions (Monitor Closely)

• Antihypertensive agents: may require blood pressure monitoring.
• Beta‑blockers: potential additive cardiovascular effects.
• Nasal corticosteroids: monitor for increased local irritation.
• Antihistamines: watch for enhanced dryness of nasal mucosa.
