Pulmicort is a brand-name inhaler that contains the corticosteroid budesonide as its active ingredient. It belongs to the therapeutic class of respiratory health medications, specifically inhaled corticosteroids (ICS). Pulmicort is available in a metered-dose inhaler (MDI) delivering 100 mcg or 200 mcg of budesonide per actuation. In Hong Kong, it is a prescription-only product regulated by the Department of Health and is commonly prescribed for the long-term management of asthma and, in some cases, chronic obstructive pulmonary disease (COPD).
Budesonide is a synthetic glucocorticoid that reduces airway inflammation by binding to intracellular glucocorticoid receptors. This interaction:
When delivered by inhalation, budesonide acts directly on the airway lining, providing high local anti-inflammatory effect while limiting systemic exposure. Onset of action is usually within a few hours, with maximal anti-inflammatory benefit developing after several days of consistent use.
Pulmicort is approved by the Hong Kong Department of Health for:
The medication is intended for regular, daily use to control underlying inflammation, not for immediate relief of acute bronchospasm.
Standard adult dosing:
200 mcg inhaler: 1-2 inhalations (200-400 mcg) twice daily, depending on disease severity.
100 mcg inhaler: 1-2 inhalations (100-200 mcg) twice daily for mild asthma.
Children (6 years and older): 100 mcg inhaler, 1-2 inhalations twice daily, titrated to symptom control.
Administration tips:
Shake the inhaler gently before use.
Exhale fully, place the mouthpiece in the mouth, and press the canister while inhaling slowly and deeply.
Hold breath for 5-10 seconds, then exhale slowly.
Missed dose: Take the missed inhalation as soon as remembered unless the next scheduled dose is within 1 hour; do not double the dose.
Overdose: Signs may include severe throat irritation, coughing, or systemic corticosteroid effects (e.g., swelling, high blood pressure). Seek emergency medical care; treatment is symptomatic.
Discontinuation: Gradual tapering is usually unnecessary for inhaled corticosteroids, but abrupt cessation may lead to rebound airway inflammation. Consult a healthcare provider before stopping.

Yes. Inhalers are allowed in both carry-on and checked baggage. Keep the inhaler in its original packaging and present it for inspection if requested.
Budesonide is not typically screened for in standard workplace or athletic drug tests. However, athletes competing under the World Anti-Doping Agency (WADA) rules should disclose inhaled corticosteroid use, as high systemic levels may require a therapeutic use exemption.
Pulmicort inhalers are white, press-urized canisters with a blue mouthpiece. The label displays “Pulmicort” and the dosage (100 mcg or 200 mcg). The canister bears a unique batch number and a Hong Kong Department of Health registration stamp.
In Hong Kong, Pulmicort is supplied as a metered-dose inhaler containing hydrofluoroalkane (HFA) propellant. Formulations in other regions may use different propellants or device designs, but the active ingredient and dosage strengths remain consistent.
Budesonide was first approved for inhaled use in the early 1990s. Over three decades of clinical experience have established its efficacy and safety as a cornerstone of asthma maintenance therapy.
Large randomized controlled trials, such as the START and FACET studies, demonstrated that regular budesonide inhalation reduces asthma exacerbations, improves lung function, and lowers the need for rescue bronchodilators. These trials informed guideline recommendations worldwide.
Switching inhaled corticosteroids should be supervised by a healthcare professional to ensure appropriate dose equivalence and to monitor for any change in asthma control.
Bathrooms can experience high humidity, which may affect inhaler performance. It is best to store the inhaler in a cool, dry place away from moisture, such as a bedroom drawer.
Dose counters can become misaligned if the inhaler is dropped or stored upside down for prolonged periods. If the counter does not match the expected remaining doses, replace the inhaler promptly.
Generic budesonide inhalers are available in Hong Kong and are typically priced lower than the branded Pulmicort. Pricing varies by pharmacy and insurance coverage; patients should consult their pharmacist for current costs.
