PRETZ NASAL (Nasal)

Uses & Indications

PRETZ NASAL is a nasal spray formulation widely used to relieve nasal congestion and related symptoms caused by various upper respiratory tract conditions. It is primarily indicated for:

  • Allergic rhinitis (seasonal and perennial): Symptoms such as nasal congestion, sneezing, runny nose, and itching caused by allergens like pollen, dust mites, or pet dander.
  • Acute viral rhinitis (common cold): Temporary nasal stuffiness and inflammation caused by viral infection.
  • Sinusitis: Inflammation of the sinuses often accompanied by nasal congestion and discharge.
  • Non-allergic rhinitis: Nasal congestion and irritation from irritants or idiopathic causes.

PRETZ NASAL can be formulated with active ingredients such as nasal corticosteroids (e.g., fluticasone, mometasone), nasal decongestants (e.g., oxymetazoline, xylometazoline), or sometimes a combination, each serving specific purposes in management.

For corticosteroid formulations, PRETZ NASAL is effective for long-term management and prevention of nasal inflammation and allergy symptoms. For decongestant formulations, it provides fast relief of nasal stuffiness.

How It Works

Depending on its formulation, PRETZ NASAL works by one or more of the following mechanisms:

1. Nasal Corticosteroids

Nasal corticosteroids in PRETZ NASAL work by targeting the underlying inflammatory pathways responsible for nasal congestion, sneezing, and runny nose in allergic and non-allergic rhinitis.

  • They bind to glucocorticoid receptors in nasal mucosal cells.
  • This binding suppresses the expression of pro-inflammatory genes and cytokines such as interleukins, tumor necrosis factor-alpha, and histamine-releasing factors.
  • The reduction in inflammatory mediators decreases swelling, mucus production, and recruitment of immune cells like eosinophils and mast cells.
  • Over days to weeks, this leads to reduced nasal mucosal edema, less mucus, and relief of congestion and other symptoms.

Because nasal corticosteroids act locally with minimal systemic absorption, they provide effective symptom control with a good safety profile when used as directed.

2. Nasal Decongestants

Nasal decongestants in PRETZ NASAL act primarily on alpha-adrenergic receptors in the blood vessels of the nasal mucosa:

  • Activation of alpha-1 adrenergic receptors causes vasoconstriction (narrowing of blood vessels).
  • This reduces blood flow to the nasal mucosa, leading to decreased swelling and edema.
  • As the swollen nasal tissue shrinks, the nasal airways open up, easing airflow and relieving the sensation of nasal blockage.
  • The onset of action is rapid, often within minutes.

However, nasal decongestants only relieve symptoms temporarily and do not treat the underlying inflammation or allergy. Prolonged use (>3 days) can cause rebound congestion due to receptor downregulation, termed rhinitis medicamentosa.

Dosage and Administration

The dosing regimen and instructions depend on the exact PRETZ NASAL formulation (corticosteroid vs. decongestant).

Corticosteroid Nasal Spray

  • Adults and children 12 years and older: Usually 1-2 sprays per nostril once daily. In some cases, dosing may be twice daily at the start of therapy.
  • Children 6 to 11 years: Often 1 spray per nostril once daily (dose may be adjusted).
  • Administration:
    • Gently blow your nose before use.
    • Shake the bottle gently if instructed.
    • Insert the nozzle into one nostril, close the other nostril by pressing it with a finger.
    • Spray while breathing in gently through the nose.
    • Repeat in the other nostril.
    • Avoid blowing your nose immediately after administration to allow absorption.

Nasal Decongestant Spray

  • Adults and children 6 years and older: 1-2 sprays in each nostril every 8 to 12 hours as needed.
  • Duration of use: Do not exceed 3 consecutive days to avoid rebound congestion.
  • Administration: Same as corticosteroid spray.
  • Important: Use for the shortest duration possible.

General Precautions for Use

  • Use exactly as prescribed or according to package instructions.
  • Do not share nasal sprays with others to avoid cross-infection.
  • Replace the cap securely after each use to keep the spray sterile.
  • Consult a healthcare provider if symptoms persist beyond 10 days or worsen.

Side Effects

Although PRETZ NASAL is generally safe when used appropriately, side effects can occur depending on the formulation and duration of use.

Common Side Effects

  • Nasal irritation or burning sensation
  • Dryness inside the nose
  • Sneezing immediately after use
  • Mild nosebleeds (epistaxis), especially with corticosteroid sprays
  • Unpleasant taste or smell
  • Headache

Less Common and Serious Side Effects

  • Prolonged use of nasal decongestants (>3 days) may cause rebound congestion (rhinitis medicamentosa), worsening nasal blockage.
  • Allergic reactions such as rash, itching, swelling, or difficulty breathing (rare).
  • Nasal septum perforation in rare cases with long-term corticosteroid use or improper use.
  • Inhaled corticosteroids may rarely cause systemic effects like adrenal suppression, growth retardation in children, or cataracts with prolonged high-dose use, though minimal with nasal delivery.

Warnings and Precautions

  • Do not exceed recommended dosage or duration — particularly important for nasal decongestants to avoid rebound congestion.
  • Use corticosteroids consistently for optimal benefit; symptom relief may take several days to manifest.
  • Avoid using nasal sprays if you have active nasal infections or injuries unless advised by a physician.
  • Monitor for signs of fungal infections or worsening nasal symptoms during prolonged corticosteroid use.
  • Caution in patients with glaucoma, cataracts, or a history of nasal ulcers or surgery.
  • Inform your healthcare provider if pregnant, breastfeeding, or planning pregnancy.
  • Keep out of reach of children and avoid accidental ingestion.
  • Avoid sharing nasal sprays to prevent contamination and infection spread.

Drug Interactions

  • Systemic interactions are rare due to low systemic absorption; however:
  • Concomitant use of other corticosteroids may increase systemic corticosteroid effects.
  • Nasal decongestants may interact with MAO inhibitors, tricyclic antidepressants, or other sympathomimetics, potentially increasing cardiovascular risks such as hypertension or arrhythmias.
  • Inform your doctor of all medications, including herbal supplements, to prevent potential interactions.

Special Populations

Pregnancy and Lactation

  • Limited data suggest nasal corticosteroids are relatively safe during pregnancy when used at recommended doses, but always consult a healthcare provider.
  • Nasal decongestants should be used cautiously in pregnancy due to potential effects on blood flow.
  • Lactating mothers should consult with healthcare providers before use.

Pediatric Use

  • Nasal corticosteroids are approved for children over 2 years in some formulations; dosing varies by age.
  • Decongestant sprays are typically recommended only for children over 6 years.
  • Safety and efficacy in younger children require medical supervision.

Geriatric Use

  • Older adults may be more sensitive to nasal decongestants due to cardiovascular risk factors; use cautiously.
  • Corticosteroids generally well tolerated but monitor for systemic effects.
