In an acute asthma exacerbation, the priority is rapid relief of bronchoconstriction and assurance of adequate oxygenation, followed by anti-inflammatory treatment and escalation if needed. Start with a quick-acting bronchodilator delivered by inhalation (a short-acting beta-agonist) to rapidly relax airway smooth muscle. If the response is incomplete or the episode is moderate to severe, add an anticholinergic bronchodilator such as ipratropium to provide additional relief. Administer systemic corticosteroids early to reduce airway inflammation and shorten the course of the attack, using oral or intravenous routes depending on the patient’s ability to take meds and the severity. Continuously monitor oxygen saturation and provide supplemental oxygen to maintain adequate oxygen levels.

If the patient remains in significant distress or doesn’t respond adequately, escalate to higher levels of support: high-flow oxygen, continuous nebulized bronchodilator therapy, or intravenous magnesium sulfate to further bronchodilate and reduce airway hyperreactivity. Admission to hospital or intensive care may be necessary for those with persistent symptoms, rising work of breathing, or signs of respiratory failure.

Antibiotics and chest X-rays are not routine parts of initial management unless there’s a specific suspected infection or another competing diagnosis, and oral antihistamines do not treat an acute asthma flare.
