When should rescue medication be used?

Rescue medication should be used during the onset of asthma symptoms, as this allows for immediate relief of acute symptoms such as wheezing, shortness of breath, and chest tightness. These medications, often fast-acting bronchodilators, are designed to quickly relax the muscles around the airways, providing prompt relief and assisting individuals in returning to their normal breathing patterns.

Using rescue medication at this stage helps prevent the situation from escalating into a more severe asthma attack. It is essential for individuals with asthma to recognize early symptoms and administer rescue medication promptly, as this can greatly influence the outcome and severity of the attack.

In contrast, using rescue medication only when symptoms are severe is not recommended because that approach may lead to worsening of the patient’s condition before relief is achieved. Taking it as a preventative measure before exercise or once daily as a routine treatment doesn’t align with its intended purpose. Rescue medications are specifically formulated for immediate relief, while long-term control medications would be used for daily management of the condition.
