AFRIN 0.05% Nasal Spray

What is AFRIN 0.05%

AFRIN 0.05% Nasal Drops contain the active ingredient Oxymetazoline Hydrochloride, a topical decongestant used to relieve nasal congestion. It belongs to the class of drugs known as sympathomimetic amines and is primarily indicated for short-term relief of nasal or sinus congestion caused by:

• Common cold
• Sinusitis
• Allergic rhinitis (hay fever)
• Upper respiratory allergies

AFRIN is widely recognized for its fast-acting relief—usually within minutes—and can provide relief for up to 12 hours per dose. It is formulated as a 0.05% solution in a 20ml nasal dropper bottle, making it suitable for both adults and children over 6 years of age under guidance.

Unlike oral decongestants, AFRIN works locally in the nasal passages without producing systemic effects such as drowsiness or increased blood pressure in most users. However, it is intended for short-term use only (typically no more than 3 days), as extended use can lead to rebound congestion or drug-induced rhinitis.

How to use AFRIN 0.05%

Proper usage of AFRIN 0.05% Nasal Drops is crucial to achieving its intended therapeutic benefits while minimizing the risk of side effects or complications. Here are the steps and key points for appropriate use:

• Blow your nose gently before using the drops to clear nasal passages.
• Wash your hands before and after application to maintain hygiene.
• Positioning: Tilt your head slightly backward or lie down with the head hanging over the edge of the bed for maximum effect.
• Instillation: Using the dropper, insert the prescribed number of drops (usually 2-3 per nostril) into each nostril.
• Inhale gently through the nose to help the medication reach deep into the nasal passages.
• Do not share the bottle to prevent the spread of infection.

Dosage frequency:

• Usually administered every 10-12 hours.
• Do not exceed 2 doses in 24 hours.
• Do not use for more than 3 consecutive days without medical advice, as it may lead to rebound congestion.

If a dose is missed, it should be applied as soon as remembered unless it's close to the next dose. Never double up on doses. Consult your physician or pharmacist if symptoms persist beyond 3 days.

Mode of Action AFRIN 0.05%

Oxymetazoline HCl, the active ingredient in AFRIN 0.05%, acts as a potent vasoconstrictor. Here's how it works:

• It stimulates the alpha-adrenergic receptors in the smooth muscle of blood vessels within the nasal mucosa.
• This leads to vasoconstriction—a narrowing of the blood vessels—which reduces blood flow to the nasal passages.
• The reduced blood flow helps to decrease the swelling and inflammation in the nasal passages and sinuses.
• As a result, there is a rapid improvement in airflow and a reduction in nasal congestion and stuffiness.

Its effects begin within minutes and usually last for up to 12 hours, offering significant symptom relief with minimal systemic absorption. Since it works directly at the site of action (the nasal mucosa), it has minimal systemic side effects when used properly.

However, prolonged or excessive use may lead to tachyphylaxis (a rapidly diminishing response to successive doses) and rebound congestion, where symptoms worsen instead of improving.

AFRIN 0.05% Interactions AFRIN 0.05%

Although AFRIN 0.05% is a topical nasal decongestant with minimal systemic absorption, it may still interact with certain medications, especially those affecting the cardiovascular or neurological systems. Caution is advised in the following cases:

• Monoamine Oxidase Inhibitors (MAOIs): Concurrent use can result in hypertensive crisis due to excessive adrenergic stimulation.
• Tricyclic Antidepressants (e.g., Amitriptyline): May enhance the pressor effect of oxymetazoline and lead to increased blood pressure.
• Beta-Blockers (e.g., Propranolol): Can exacerbate blood pressure changes or reduce effectiveness of both drugs.
• Antihypertensives: AFRIN may diminish the effects of antihypertensive medications by causing vasoconstriction.
• Sympathomimetic drugs (e.g., pseudoephedrine): Using multiple vasoconstrictors can increase risk of systemic side effects like palpitations or nervousness.

Always inform your healthcare provider about all medications you are currently taking, including over-the-counter cold or allergy medications, herbal supplements, and vitamins, before using AFRIN.

Dosage of AFRIN 0.05%

The dosing regimen of AFRIN 0.05% must be followed strictly to avoid rebound effects and ensure safe use. Below is a general guideline; however, specific dosing should always follow a healthcare provider’s advice.

• Adults and children over 6 years:
• 2-3 drops in each nostril
• Not more than twice daily (every 10-12 hours)
• Maximum: 2 doses per 24 hours
• Children under 6 years:
• Use is generally not recommended unless advised by a pediatrician.
• Lower concentration formulations may be preferred for this age group.
• Duration of Use:
• Do not exceed 3 consecutive days of use to avoid rebound nasal congestion (rhinitis medicamentosa).

If symptoms persist or worsen, seek medical attention. AFRIN should not be used as a long-term solution for nasal congestion. Repeated or prolonged use increases the risk of chronic nasal mucosa damage.

Possible side effects of AFRIN 0.05%

Like all medications, AFRIN 0.05% may cause side effects, although not everyone experiences them. When used as directed for short-term relief, most users tolerate it well. However, adverse effects may occur, especially with overuse or prolonged use.

• Common side effects:
• Transient nasal burning or stinging
• Nasal dryness or irritation
• Sneezing
• Temporary increase in nasal discharge (runny nose)
• Less common side effects:
• Headache
• Palpitations
• Restlessness or insomnia (especially in children)
• Nausea
• Serious side effects (rare):
• Rebound congestion upon withdrawal
• Elevated blood pressure
• Rapid or irregular heartbeat
• Allergic reactions (rash, swelling, difficulty breathing)

Discontinue use and consult a doctor if side effects are severe or persistent, particularly rebound congestion or cardiovascular symptoms.

AFRIN 0.05% Contraindications AFRIN 0.05%

AFRIN 0.05% should not be used in individuals with the following conditions unless specifically advised by a physician:

• Patients using MAO inhibitors or within 14 days of stopping such therapy
• Severe hypertension or coronary artery disease
• Narrow-angle glaucoma
• Children under 6 years of age (unless directed by a pediatrician)
• History of chronic rhinitis medicamentosa (rebound nasal congestion due to long-term decongestant use)

Caution is also advised in patients with thyroid disorders, diabetes mellitus, and prostatic hypertrophy, due to the risk of systemic sympathomimetic effects.

Storage of AFRIN 0.05%

To ensure the efficacy and safety of AFRIN 0.05% Nasal Drops, proper storage conditions must be maintained:

• Store at room temperature: ideally between 15°C to 25°C (59°F to 77°F).

• Keep the bottle tightly closed when not in use to avoid contamination.
• Do not freeze. Freezing can degrade the solution and damage the dropper mechanism.
• Keep out of reach of children.
• Check the expiry date before use. Do not use expired medication.

Always discard the bottle if the solution becomes discolored, cloudy, or if the dropper is visibly contaminated. For safety and optimal results, follow label instructions and pharmacist recommendations.
