How Do You Administer Intranasal Medication Correctly?

Did you know that intranasal drug delivery can offer a more rapid onset of action compared to oral medication for certain conditions? This is because it bypasses the digestive system and liver metabolism, making it a highly effective method. This guide explains how do you administer intranasal medication using various devices for optimal results.

Quick Summary

This resource provides step-by-step instructions on correctly administering intranasal medications, explaining the proper techniques and common devices used for safe and effective absorption.

Key Points

• Positioning is Key: Tilt your head forward, not back, for most nasal sprays to prevent the medicine from dripping down your throat.

• Aim Away from the Center: To avoid irritation and bleeding, point the nozzle towards the outside of your nostril, away from the central septum.

• Gentle Inhale is Best: Inhale slowly and gently as you spray, as a strong sniff can send the medication to your throat where it is less effective.

• Atomizer Technique is Brisk: When using a mucosal atomization device (MAD), push the plunger quickly and firmly to create a fine mist for better absorption.

• Clear Nasal Passages First: Gently blow your nose before use to clear mucus, which can act as a barrier to absorption.

• Prime the Pump: If using a new spray bottle or one that hasn't been used recently, prime it by pumping it a few times until a mist appears.

• Don't Share Devices: To prevent the spread of bacteria and contamination, never share intranasal spray bottles.

Understanding the Mechanism: Why Intranasal is Effective

Intranasal drug delivery offers a powerful pathway for medication absorption that is both rapid and efficient. The key to this effectiveness lies in the unique anatomy of the nasal cavity. The nasal mucosa, the inner lining of the nose, is highly vascularized, meaning it contains a dense network of tiny blood vessels. This rich blood supply allows medications to be absorbed directly into the systemic circulation, bypassing the gastrointestinal tract and the liver. Avoiding first-pass metabolism in the liver can significantly increase the bioavailability of certain drugs, meaning more of the medicine reaches its target.

Furthermore, for some medications, the intranasal route may also facilitate a direct pathway to the brain via the olfactory and trigeminal nerve pathways. This can be particularly beneficial for drugs targeting central nervous system disorders. Proper technique is crucial to maximize these benefits and ensure the medication is absorbed correctly rather than dripping down the throat or out of the nose.

Proper Technique for Standard Nasal Sprays

Standard nasal sprays, commonly used for allergies or congestion, require specific steps to ensure the medicine reaches the sinuses and is absorbed effectively.

Before You Begin

• Wash Your Hands: Always start by washing your hands thoroughly with soap and water to prevent contamination.
• Clear Your Nose: Gently blow your nose to clear any mucus that might block the medication from being absorbed. Avoid blowing too forcefully.
• Prime the Pump: If it's a new bottle or hasn't been used in a while, prime the pump by spraying it a few times into the air until a fine mist appears. This ensures a full and accurate dose.
• Check Dosage: Always check the medication label for specific dosing instructions, especially regarding the number of sprays and which nostril to use.

Step-by-Step Application

1. Head Position: Tilt your head slightly forward, not backward. Tilting forward helps the spray reach the sinuses and prevents it from running down the back of your throat.
2. Insert and Aim: Gently insert the tip of the bottle into one nostril. Use your other hand to press on the opposite nostril to close it off. Critically, aim the nozzle towards the outside of your nostril, away from the central septum (the wall dividing your nostrils).
3. Spray and Inhale: As you begin to breathe in slowly through your nose, press down firmly and quickly on the spray bottle to release the medicine. A gentle sniff is all that is needed; a hard sniff can send the medicine to your throat.
4. Repeat if Necessary: If you require a spray in the other nostril, repeat the steps for that side.
5. Clean Up: Wipe the nozzle with a clean tissue and replace the cap. Avoid blowing your nose for 5 to 10 minutes to allow for absorption.

Utilizing a Mucosal Atomization Device (MAD)

For certain emergency medications, healthcare providers may use a Mucosal Atomization Device (MAD), which attaches to a syringe. This device creates a fine mist, which improves absorption and is often used in a hospital or pre-hospital setting for medications like naloxone or midazolam.

Procedure with a MAD

1. Prepare the Dose: Draw the correct dose of medication into a syringe. It is often recommended to draw up a small amount extra to account for the "dead space" in the atomizer device.
2. Attach the Atomizer: Securely twist the MAD onto the end of the syringe.
3. Position the Patient: The patient should be positioned correctly, often with their head tilted back slightly.
4. Aim and Administer: Insert the tip of the MAD snugly into the nostril, aiming slightly up and out toward the ear on the same side. This ensures maximum surface area coverage. Quickly and briskly compress the syringe plunger to expel the medication as a fine mist.
5. Divide the Dose: If the dose volume is greater than 0.5 mL, divide it and administer half into each nostril for better absorption.
6. Discard Safely: The MAD and syringe are for single-use and should be discarded safely after administration.

Comparison of Intranasal Drug Delivery Methods

Effective intranasal administration depends on using the right technique for the specific delivery device. The following table compares standard nasal sprays with Mucosal Atomization Devices (MADs).

Feature	Standard Nasal Spray	Mucosal Atomization Device (MAD)
Mechanism	A pump-activated bottle sprays medication into the nasal passages.	An atomizer attached to a syringe expels a high-velocity, atomized mist.
Delivery Speed	Pressure-dependent; can vary. Requires a slow, gentle inhale from the patient.	Very fast and forceful, designed for rapid misting and absorption.
Dose Precision	Consistent, pre-metered dose per pump.	Very precise due to syringe control, but requires careful measurement and preparation.
Target Area	Primarily local effect for allergies and congestion; some systemic absorption.	Rapid systemic absorption via the nasal mucosa, often for emergency use.
User Skill	Relatively easy for self-administration after initial instruction.	Requires more training, typically used by healthcare professionals or trained caregivers.
Common Examples	Fluticasone (Flonase), Oxymetazoline (Afrin).	Naloxone (Narcan) kits, Midazolam for seizures.
Preparation	Shake and prime the pump before first use or if unused for some time.	Draw up the medication into the syringe and attach the atomizer.

Common Errors to Avoid During Administration

To ensure efficacy and minimize side effects, be aware of these common mistakes:

• Incorrect Head Position: Tilting the head back excessively causes medication to drain into the throat, where it is less effectively absorbed and can taste unpleasant.
• Sniffing Too Forcefully: A hard sniff can pull the medicine past the nasal cavity and into the back of the throat and stomach.
• Ignoring a Blocked Nose: Trying to spray into a congested nose will result in poor absorption. Always clear the nasal passages first.
• Not Priming the Device: Failing to prime a new or unused pump spray results in an inconsistent dose being delivered.
• Spraying the Septum: Aiming towards the center of the nose, at the septum, can cause irritation and nosebleeds, reducing effectiveness.
• Immediately Blowing Nose: Blowing your nose too soon after administration removes the medication before it has had a chance to be absorbed.
• Sharing Devices: Each intranasal device should be used by only one person to prevent the spread of germs.

Key Best Practices for Safe Intranasal Delivery

Following a few simple guidelines can improve the safety and effectiveness of intranasal medication delivery:

• Read Instructions Thoroughly: Always read the manufacturer's instructions for your specific medication, as techniques can vary slightly between products.
• Practice Good Hygiene: Always wash your hands before and after administration to minimize the risk of contamination and infection.
• Use the Crossover Method: For standard nasal sprays, use your right hand to spray the left nostril and your left hand for the right nostril. This technique naturally angles the spray away from the septum.
• Store Properly: Ensure the medication is stored according to the manufacturer's directions, often at room temperature.
• Monitor for Side Effects: Be aware of potential side effects such as nasal irritation or congestion and report any persistent issues to a healthcare provider.
• Educate All Caregivers: If the medication is for a dependent individual, ensure all caregivers are properly trained on the correct technique.
• Dispose of Used Devices Safely: Follow instructions for safe disposal of single-use devices like MADs.

Frequently Asked Questions

What is the benefit of intranasal administration over other routes?

It provides a rapid onset of action, avoids first-pass metabolism in the liver, and is a non-invasive alternative to injections. For certain medications, it may also allow for direct delivery to the brain.

Can I use the same technique for all types of nasal sprays?

No, different devices like standard pump sprays and mucosal atomization devices (MADs) require different techniques. Always follow the manufacturer's instructions for your specific product.

Why is it important to aim the spray away from the nasal septum?

The septum is highly vascular, and spraying directly on it can cause irritation or nosebleeds. Aiming outward directs the medication to the more absorbent turbinates for better absorption.

What happens if I sniff too hard during administration?

Sniffing too hard can cause the medicine to drip down the back of your throat, where it is swallowed and less effectively absorbed into the nasal mucosa.

What is a Mucosal Atomization Device (MAD)?

A MAD is a device that attaches to a syringe to convert liquid medication into a fine, aerosolized mist. It is often used for emergency medications due to its fast and effective delivery.

Is it okay to blow my nose immediately after using the spray?

It is best to wait 5-10 minutes after administration. Blowing your nose too soon will likely remove the medication before it has had a chance to be absorbed.

How do I prepare a new spray bottle for its first use?

You must "prime" the pump by spraying a few times into the air until a fine mist is visible. This ensures the correct, full dose is delivered on the first use.

Can I share my nasal spray with someone else?

No, you should never share your intranasal spray bottle. Sharing can spread bacteria and other contaminants, potentially causing infection.
