What Does a Blue Inhaler Mean for Your Asthma?

An inhaler delivers medication directly into the lungs to manage respiratory conditions. Among the various types, the blue inhaler holds a specific and important role in managing asthma symptoms. Understanding its purpose and how it functions is crucial for anyone relying on this device for respiratory support.

The Blue Inhaler’s Primary Function

The blue inhaler is known as a “reliever” or “rescue” inhaler, providing rapid relief from asthma symptoms. It contains salbutamol, also known as albuterol in some regions, a short-acting beta-agonist (SABA). This medication works by stimulating specific receptors, called beta2-adrenergic receptors, located in the smooth muscles surrounding the airways. When these receptors are activated, the muscles relax, causing the airways to widen and making breathing easier. This mechanism allows for quick relief of symptoms like wheezing, chest tightness, and shortness of breath.

Using a Blue Inhaler

A blue inhaler is intended for immediate relief during sudden onset of asthma symptoms, such as wheezing, coughing, or shortness of breath. It is not typically used for daily, preventative control of asthma but rather as an as-needed treatment for flare-ups or before engaging in activities known to trigger symptoms, like exercise.

To use a metered-dose inhaler:
Shake the inhaler.
Exhale fully.
Place the mouthpiece in the mouth.
Inhale slowly and deeply as the canister is pressed to release the medication.
Hold your breath for about 5 to 10 seconds.
If a second puff is needed, it is generally recommended to wait about one minute before taking it.

Blue Inhalers Versus Other Types

The blue inhaler’s role is distinct from other inhaler types, which often come in different colors like brown, purple, or red. While the blue inhaler acts as a “reliever” for immediate symptom alleviation, these other colored inhalers typically serve as “preventer” or “maintenance” medications. Preventer inhalers usually contain corticosteroids, which work to reduce inflammation in the airways over time, aiming to prevent symptoms from occurring in the first place. Unlike the blue inhaler, preventer inhalers must be used daily, even when feeling well, to maintain long-term asthma control. The blue inhaler does not treat the underlying inflammation; it only provides temporary relief from tightened airways.

Key Points for Safe Use

While generally safe, using a blue inhaler can sometimes lead to mild side effects such as shakiness, nervousness, a rapid heartbeat, dizziness, or a sore throat. These effects are usually temporary and resolve as the medication wears off. More importantly, frequent reliance on a blue inhaler, such as needing it more than two or three times a week or finishing an entire canister within a month, can indicate that asthma is not well-controlled. Overusing the inhaler might reduce its effectiveness over time and could even worsen asthma control, potentially leading to an increased risk of severe asthma attacks.

It is important to seek medical attention if:
Symptoms do not improve after using the inhaler.
Symptoms worsen.
There is difficulty walking, talking.
Lips or nails turn blue.
