Asthma Management Guide Malaysia: Triggers, Inhalers & Control

Identifying and avoiding your personal triggers is one of the most important aspects of asthma management. Malaysian asthma patients face specific environmental challenges. House dust mites: the most common indoor trigger worldwide — and particularly prevalent in Malaysia's warm, humid climate. Dust mites live in mattresses, pillows, carpets, and soft furnishings. Practical control measures: use dust mite-proof mattress and pillow covers, wash bedding in hot water (above 60 degrees C) weekly, reduce soft furnishings (remove carpets if possible), use air-conditioning or dehumidifiers to keep indoor humidity below 50%. Haze (jerebu): the annual transboundary haze from peat fires in Indonesia is a major acute asthma trigger in Malaysia. PM2.5 particles penetrate deep into the airways. During high API (Air Pollutant Index) days: stay indoors, keep windows closed, use air purifiers with HEPA filters, and carry your reliever inhaler at all times. Air pollution: vehicle exhaust fumes, factory emissions, and traffic pollution affect urban Malaysians daily. Cycling or walking near busy roads can trigger attacks. Mould and dampness: Malaysia's humidity promotes mould growth in bathrooms, kitchens, and air-conditioning units. Clean air-con filters monthly. Pets: cat and dog dander is a potent trigger. If you have asthma and own pets, keep pets out of the bedroom, bathe them weekly, and use HEPA air purifiers. Other triggers: tobacco smoke (secondhand smoke is a powerful trigger), respiratory infections (the most common cause of asthma exacerbations), exercise in cold or dry air, strong perfumes and chemical fumes, aspirin and NSAIDs (in aspirin-sensitive asthmatics), beta-blocker medications (including eye drops), and emotional stress.

Up to 70 to 80% of asthma patients use their inhaler incorrectly, often without knowing it. Poor inhaler technique is one of the most common reasons for poorly controlled asthma — the medication simply does not reach the airways effectively. For a pressurised Metered Dose Inhaler (pMDI — the classic blue or brown inhaler): 1. Remove the cap and shake the inhaler vigorously for 2 seconds 2. Breathe out fully 3. Place the mouthpiece in your mouth and create a seal with your lips 4. Begin breathing in slowly and deeply, then press the canister down to release one puff 5. Continue breathing in slowly until your lungs are full (about 4 to 5 seconds) 6. Remove the inhaler and hold your breath for 10 seconds 7. Breathe out slowly 8. Wait 1 minute before a second puff if required 9. Rinse your mouth after using a corticosteroid inhaler to prevent oral thrush Using a spacer device significantly improves drug delivery to the lungs — highly recommended for children and adults with poor coordination. A spacer is a chamber attached to the inhaler that allows you to breathe in the medication without needing perfect timing. For dry powder inhalers (DPI) such as Turbuhaler or Accuhaler: - No need to shake - Breathe out fully (away from the inhaler) - Seal lips around the mouthpiece - Breathe in as fast and deeply as possible - Hold breath for 10 seconds At Klinik Muhibbah, our doctors and nurses can demonstrate correct inhaler technique at each visit. This is as important as prescribing the right medication.
