What should you know about allergic asthma medication?

A preventer or anti-inflammatory inhaler reduces sensitive, swollen airways over time, while a prescribed reliever opens narrowed airways when symptoms occur. Some combination inhalers can serve both purposes. The right device and schedule depend on age, symptom pattern, previous flare-ups, other health conditions, and the medicines already being used.

Allergic triggers such as dust mites, pollen, mould, or animal dander can set off inflammation and tightening in susceptible airways. Inhaled corticosteroids target that inflammation; they are not the same as anabolic steroids. Reliever medicines relax airway muscles, but relief alone does not treat the underlying inflammation.

Treatment for nasal allergy may also reduce an important trigger burden when allergic rhinitis accompanies asthma, but it does not replace asthma medicine. Tablets or injectable biologic medicines may be considered for selected people whose asthma remains difficult to control after diagnosis, adherence, inhaler technique, and exposures have been reviewed.

Follow the label and your written action plan because inhalers that look similar can contain different medicines. Ask a clinician or pharmacist to watch your technique, and use a spacer if one is prescribed. Keep the mouthpiece clean, check the dose counter and expiry date, and arrange a replacement before the inhaler runs out.

Rinse your mouth and spit after a corticosteroid inhaler to reduce hoarseness and oral thrush. Report tremor, a racing heartbeat, persistent mouth soreness, or any new symptom after a medicine change. Do not stop a preventer suddenly or borrow another person's inhaler. Needing relief more often, waking with symptoms, or limiting activity warrants a treatment review.

Seek emergency help for severe breathlessness, difficulty speaking in full sentences, blue or grey lips, confusion, exhaustion, collapse, or rapidly worsening chest tightness. Sit upright and use the prescribed reliever exactly as the personal action plan directs while help is arranged.

Emergency assessment is also needed when the reliever is not helping, there is no reliever available during marked breathing difficulty, or symptoms return quickly after initial relief. Do not delay urgent care to search for a suspected allergen or to try an unprescribed remedy.

Ask which inhaler is the preventer, which one should relieve symptoms, and whether one device has both roles. Confirm what changes in cough, wheeze, night waking, activity, or peak-flow readings should trigger each part of your action plan.

Bring every inhaler, spacer, and a list of other medicines to the visit. Useful topics include technique, possible side effects, safe exercise, managing nasal allergy, avoiding relevant triggers, and what to do if a dose is missed or the device is lost while travelling.
