Asthma Treatment in Bangkok: Inhalers, Nebulizer and 24/7 Review
How Doctor Bangkok assesses asthma control, delivers acute treatment, and uses the GINA 2024 stepwise plan.
Clinically reviewed by Dr. Ponlawat Pitsuwan, Physician, Doctor Bangkok
Asthma is a chronic inflammatory airway disease that causes reversible bronchoconstriction, cough, wheeze and shortness of breath. Good control means few daytime symptoms, no night waking, and no reliever use beyond 2 days a week. Doctor Bangkok treats acute exacerbations with salbutamol nebulisation or spacer-delivered bronchodilator, oral or intravenous corticosteroids when indicated, and reviews long-term control based on the GINA 2024 stepwise plan, now built around low-dose ICS-formoterol.
From the clinic: The single biggest change in asthma management in the last decade is that salbutamol-only treatment is now actively discouraged by GINA: repeated short-acting beta-agonist use alone is linked to more exacerbations and more deaths. I still meet patients on “just a blue inhaler when I need it” whose risk is not being managed. Control and rescue inhalers do different jobs, and both usually matter.
Acute flare: what actually helps
During an asthma flare the priorities are fast oxygenation and rapid bronchodilation. At Doctor Bangkok we deliver salbutamol either through a spacer (which works as well as a nebuliser in most mild to moderate flares) or through a nebuliser in severe cases, with oxygen titrated to keep saturations above 94 percent. For moderate or severe flares we add ipratropium nebulisation and start oral prednisolone 40 to 50 mg daily for 5 to 7 days, per the British Thoracic Society and GINA recommendations. Peak expiratory flow (PEF) and saturations guide escalation. Severe flares that fail to respond after three rounds of bronchodilator, or patients with drowsiness, a silent chest, or peak flow below 33 percent of predicted, need hospital transfer, not ongoing outpatient management.
| Mild flare | Severe / life-threatening |
|---|---|
| Talks in full sentences | Cannot complete a sentence |
| PEF above 75% of best | PEF below 50%; 33% is life-threatening |
| SpO2 above 94% | SpO2 below 92% |
| Salbutamol via spacer at home | Nebulised salbutamol + ipratropium |
| Oral steroid if needed | Oral or IV steroid, oxygen, hospital |
| Review technique and action plan | Call emergency services |
Long-term control: GINA 2024 in plain language
GINA 2024 recommends that no adult or adolescent with asthma should be on a short-acting beta-agonist alone. For mild asthma, as-needed low-dose ICS-formoterol (an inhaled corticosteroid combined with formoterol) has replaced “SABA only” at step 1. For more persistent symptoms we step up to a maintenance and reliever therapy (MART) regimen using the same ICS-formoterol both daily and as needed. Severe or poorly controlled asthma may need higher ICS doses, a long-acting muscarinic antagonist such as tiotropium, or biologic therapy. The review visit matters: many patients are under-treated because no one has checked their inhaler technique or counted their reliever use. Concurrent flu symptoms or upper respiratory infection often trigger flares and need treating at the same visit.
When to see a doctor
Book an urgent appointment for a new diagnosis of wheeze, for symptoms waking you from sleep, for reliever use beyond twice a week, or for any flare that does not settle within 30 minutes of reliever use. Seek same-day emergency care for severe shortness of breath, inability to speak in full sentences, blue lips, peak flow below 50 percent of best, or failure to respond to four puffs of salbutamol delivered via spacer every 20 minutes. These signs represent a severe or life-threatening flare and need oxygen, nebulisation and hospital review. Silent chest, drowsiness and exhaustion are pre-arrest signs and warrant immediate ambulance call.
Red flag: If red-flag symptoms appear, do not wait. Book same-day or present to the nearest emergency department as described above.
Prevention and trigger control
Annual influenza vaccination is the single most under-used asthma intervention and reduces exacerbation rates meaningfully. Pneumococcal vaccination is recommended for most adult asthmatics per CDC/ACIP. Identify and reduce triggers: house dust mite with mattress encasings and regular bed washing at 60 degrees, cockroach control in older buildings, cigarette smoke including secondhand, and outdoor air pollution during high-PM days in Bangkok. Treat coexisting allergic rhinitis with a daily intranasal steroid, as uncontrolled rhinitis directly worsens asthma control. Keep a written asthma action plan so you know when to step up treatment and when to seek help.
Inhaler technique: the overlooked half of asthma care
Up to half of asthma patients get little benefit from their inhaler because they use it incorrectly. Pressurised metered-dose inhalers should be used with a spacer in most adults and all children under 12. Dry powder inhalers need a fast, forceful inhalation; MDIs need a slow, deep one. We review technique at every visit and re-demonstrate it when control is poor. No new drug will rescue a badly-used inhaler.
Summary
Modern asthma care is built on two ideas: never use a reliever without a controller, and check inhaler technique at every visit. Those two shifts prevent more hospital admissions than any clever new molecule. As Dr. Pitsuwan puts it: “If you are using your blue inhaler more than twice a week, your asthma is not controlled, even if you think it is.” Doctor Bangkok provides 24/7 acute asthma review and long-term control plans from our Sukhumvit clinic and across our 24/7 medical services.
Frequently asked questions
How do I know if my asthma is controlled?
Few daytime symptoms, no night waking, no activity limitation, and reliever use no more than twice a week. An Asthma Control Test (ACT) score of 20 or higher also indicates good control.
Is it safe to take steroid inhalers long term?
Yes. Inhaled corticosteroids at standard doses have a strong long-term safety profile. The risks of poorly controlled asthma far outweigh those of the inhaler.
What is the difference between a reliever and a preventer?
A reliever (salbutamol) opens airways quickly but does nothing for underlying inflammation. A preventer (inhaled corticosteroid) treats the inflammation and prevents flares. Most patients need both; some need a combination.
Can I use a nebuliser at home?
A spacer is as effective as a nebuliser for most mild to moderate flares and is portable. Home nebulisers are reasonable for some severe asthmatics but must be part of a written action plan, not a substitute for clinic review.
How often should I see a doctor about my asthma?
At least annually if well controlled, every 3 months if not. Every visit should include inhaler technique review, symptom count, and peak flow check.
Does air pollution in Bangkok affect my asthma?
Yes. High PM2.5 days correlate with more flares in asthma patients. Check daily AQI, reduce outdoor exercise on bad days, and consider an N95 mask or indoor HEPA filter during high-exposure weeks.
