Asthma Treatment: Why a Reliever Inhaler Alone Is Not a Plan
Asthma has two separate problems happening in the same airways. The first is bronchoconstriction: the muscle wrapped around the airway tightens, and the tube narrows within minutes. The second is inflammation: the lining is swollen, irritable and producing mucus, and it stays that way between attacks even when breathing feels normal.
A reliever inhaler relaxes the muscle. It does nothing to the inflammation. That distinction is the whole of asthma treatment, and getting it wrong is the reason people still die of a condition that is almost always controllable.
⚠️ The change that matters most, and that many people have not been told. Treating asthma with a reliever inhaler alone is no longer recommended for anyone over the age of 12. It leaves the inflammation untreated, and studies consistently link reliever-only use to more severe attacks and to asthma deaths. Every adolescent and adult with asthma should be on treatment that contains an inhaled corticosteroid. Needing a reliever more than twice a week is a sign that the plan is wrong, not that the reliever is working.
📊 How much reliever is too much
Reliever use is the single most informative thing a person can report, and it is measurable.
| Pattern of reliever use | What it means |
|---|---|
| Twice a week or less | Reasonable control |
| Three or more times a week | Not controlled; treatment needs stepping up |
| Waking at night with symptoms | Not controlled, regardless of daytime |
| Three or more canisters in a year | Associated with a substantially higher risk of a severe attack |
| Twelve or more canisters in a year | Associated with increased risk of death from asthma |
A reliever that works beautifully is reassuring and misleading. It confirms the diagnosis and says nothing about whether the underlying inflammation is being treated.
🔬 Confirming the diagnosis
Asthma is diagnosed on a combination of typical symptoms and demonstrated variable airflow obstruction. Symptoms alone are not enough, because breathlessness and cough have many causes.
- 📈 Spirometry with reversibility testing — airflow measured before and after a reliever. An improvement in FEV1 of at least 12 percent and 200 mL confirms reversible obstruction
- 📉 Peak flow variability — readings taken morning and evening for two weeks. Asthma typically varies by more than 10 percent across the day, and is worst in the early morning
- 💨 FeNO — nitric oxide in exhaled breath, raised in the type of airway inflammation that responds to steroids. A useful pointer, not a standalone test
- 🏃 Exercise challenge where symptoms are exercise-related
- 🌼 Allergy testing where a specific trigger is suspected
A normal spirometry result between attacks does not exclude asthma, which is why repeat testing or a trial of treatment is sometimes needed.
💊 The treatment ladder
Treatment moves up or down in steps, reviewed every few months. Down as well as up: once control has been stable for three months, the aim is the lowest dose that maintains it.
| Step | Treatment | Our products |
|---|---|---|
| 1 to 2 | Low-dose inhaled corticosteroid, plus a reliever | Flovent (Fluticasone), Pulmicort (Budesonide), with Ventolin (Albuterol) or Proventil (Albuterol) |
| 3 | Low-dose ICS combined with a long-acting bronchodilator in one inhaler | Advair Diskus (Fluticasone and Salmeterol) |
| 4 | Medium or high-dose ICS with a long-acting bronchodilator; add-on options | Plus Singulair (Montelukast) or Spiriva (Tiotropium) |
| 5 | Specialist assessment; biologic therapy for severe eosinophilic or allergic asthma | Not stocked; hospital-administered |
⛔ A long-acting bronchodilator is never used alone in asthma. Used without an inhaled corticosteroid, a LABA controls symptoms while inflammation progresses unchecked, and trials found increased asthma deaths. That is why it is dispensed as a combination inhaler. If someone with asthma is holding a salmeterol or formoterol inhaler with no steroid alongside it, that prescription needs reviewing urgently. In COPD the rule is different; in asthma it is absolute.
Tiotropium, normally a COPD drug, has a genuine role as an add-on in asthma that stays uncontrolled on a combination inhaler, and it is available as Tiova (Tiotropium) as well.
💨 Inhaler technique: where most treatment is lost
Studies of patients using their own inhalers find that a large majority make at least one error that meaningfully reduces the dose reaching the lungs. A correctly used cheap inhaler beats an incorrectly used expensive one.
🗜️ Pressurised aerosol inhalers
- Shake, and prime a new or unused inhaler with a test spray
- Breathe out fully, away from the inhaler
- Seal lips around the mouthpiece
- Press and breathe in slowly and deeply at the same time, over four to five seconds
- Hold the breath for ten seconds, then breathe out gently
- Wait about 30 seconds before a second puff
💿 Dry powder inhalers
The opposite technique: breathe in hard and fast, because the device needs the force of the breath to break up the powder. A slow inhalation delivers very little. These also must be kept dry, and never exhaled into.
📦 Use a spacer with any aerosol inhaler. It removes the need to coordinate pressing and breathing, roughly doubles the dose reaching the lungs, and cuts the amount deposited in the mouth and throat, which reduces thrush and hoarseness. One puff at a time into the spacer, then three to five slow breaths. Washed in warm soapy water and left to air-dry without rinsing or wiping, because drying with a cloth creates static that traps the drug on the walls.
🚰 Rinse the mouth after every steroid inhaler dose. Rinse, gargle and spit out. This prevents oral thrush and hoarseness, which are the two side effects that make people abandon controller treatment, and they are almost entirely avoidable.
🚦 A written action plan
An action plan converts asthma from something that happens to you into something with instructions. It is built around personal best peak flow, measured when asthma is well controlled.
| Zone | Peak flow | What to do |
|---|---|---|
| 🟩 Green | 80 to 100 percent of personal best | Continue the usual controller. No reliever, or rarely |
| 🟨 Amber | 50 to 79 percent | Use the reliever as directed, step up the controller as your plan specifies, and contact the clinic if not improving within 48 hours |
| 🟥 Red | Below 50 percent | Reliever immediately, start the oral steroid course if one has been prescribed for this purpose, and seek urgent medical help |
Many people are given a short course of prednisolone to keep at home for exactly this situation, typically 40 mg daily for five days, with instructions on when to start it. Plans of this kind reduce hospital admissions.
🚨 The signs of a severe attack
🚑 Call emergency services for any of these.
- Cannot complete a sentence in one breath, or cannot speak
- The chest has gone quiet — wheezing has stopped while breathing is still a struggle
- Blue or grey lips or fingertips
- Drowsiness, confusion or exhaustion
- The reliever is not helping, or is needed again within an hour or two
- Straining to breathe, with ribs and neck muscles visibly pulling
A silent chest is more dangerous than a loud wheeze. Wheezing is the sound of air forcing through a narrowed tube; when the narrowing becomes severe enough, too little air moves to make any sound at all. Both patients and relatives often interpret the quiet as improvement, which is why this point is worth knowing before it is needed.
While waiting for help: sit upright, do not lie down, and take one puff of the reliever every 30 to 60 seconds, up to ten puffs, ideally through a spacer.
🧩 Triggers, including the ones in a medicine cabinet
- Viral infections
- The most common cause of asthma attacks by a wide margin, and the reason attacks cluster in autumn and winter. Annual influenza vaccination matters here.
- Allergens
- House dust mite, pollen, animal dander, mould. Mite reduction takes mattress covers, 60 degree washing and hard flooring in the bedroom; half-measures achieve little.
- Exercise
- Exercise-induced narrowing peaks 5 to 10 minutes after stopping, not during. Well-controlled asthma usually makes it disappear. A reliever 15 minutes before exercise and a proper warm-up handle the rest, and swimming in warm humid air is better tolerated than cold-air running.
- Cold dry air
- Breathing through a scarf over the nose and mouth in winter helps measurably.
- Reflux, rhinitis and sinus disease
- All worsen asthma and all are treatable. Untreated nasal disease is a common reason asthma stays poorly controlled.
- Smoke, including passive and vaping
- Smoking also makes inhaled steroids work less well, so it reduces the effect of the treatment as well as worsening the disease.
💊 Two groups of medicines that trigger asthma.
Aspirin and other NSAIDs provoke attacks in roughly one in ten adults with asthma, and the rate is far higher in those who also have nasal polyps and a poor sense of smell. Reactions can be severe and start within an hour. Anyone with asthma plus nasal polyps should treat ibuprofen, diclofenac, naproxen and aspirin as suspect until a doctor has confirmed they are safe. Paracetamol is generally tolerated.
Beta-blockers can cause bronchospasm, and that includes eye drops such as timolol used for glaucoma, which are absorbed systemically. Always tell an eye clinic about asthma.
💡 What to know about each controller
🟦 Inhaled corticosteroids
The foundation of treatment. They reduce inflammation over days to weeks, so they do nothing for an acute attack and must be taken every day whether or not symptoms are present — the commonest reason they fail is being used only when unwell.
Side effects at low to moderate dose are local rather than systemic: oral thrush and a hoarse voice, both largely preventable with a spacer and mouth rinsing. In children, inhaled steroids slow growth velocity slightly in the first year with a small effect on final height, which is far outweighed by the risks of undertreated asthma.
🟧 Montelukast
A tablet rather than an inhaler, taken once daily in the evening, useful as an add-on and particularly where asthma coexists with allergic rhinitis or is exercise-related. Weaker than an inhaled steroid and not a substitute for one.
🧠 Montelukast carries a specific warning about mood and behaviour. Regulators added a boxed warning after reports of nightmares, vivid dreams, agitation, depression, aggression and suicidal thoughts, including in children and in people with no psychiatric history. It usually appears within the first weeks. Anyone starting it, or any parent giving it to a child, should know to stop it and seek advice if behaviour or mood changes. The symptoms resolve on stopping.
🟩 Oral steroids
Reserved for attacks, as short courses. Repeated courses — more than two a year — are themselves a marker of poorly controlled asthma and a trigger for specialist referral, because the cumulative effects on bone, glucose and eyes add up.
🤰 Asthma in pregnancy
The principle is short and often misunderstood: uncontrolled asthma is far more dangerous to a pregnancy than asthma medicines are. Poor control is associated with low birth weight, pre-eclampsia and preterm birth, while inhaled steroids and relievers have a long safety record. Controller treatment is continued, not reduced, and attacks are treated promptly, including with oral steroids where needed. Asthma changes in pregnancy unpredictably, improving in about a third of women and worsening in about a third, so review is more frequent rather than less.
📅 Staying in control
- 🔍 Review every 3 to 6 months, and after every attack
- 💨 Technique checked at every review, not just at the start. It deteriorates over time in most people
- 📈 Peak flow diary during unstable periods, and a known personal best
- 💉 Influenza vaccine annually, and pneumococcal where advised
- 📉 Step down when stable for three months, to the lowest effective dose
- 👀 Watch the reliever count, which is the earliest objective sign that control is slipping
❓ Frequently asked questions
Is a reliever inhaler on its own enough?
No, and it is no longer recommended for anyone over 12. A reliever relaxes the airway muscle but leaves the inflammation untreated, and reliever-only use is linked to more severe attacks and to asthma deaths. Treatment containing an inhaled corticosteroid is needed.
How often is it acceptable to use a reliever?
Twice a week or less. Three or more times a week, or waking at night with symptoms, means asthma is not controlled. Using three or more canisters a year is associated with a substantially higher risk of a severe attack.
Do I have to take a steroid inhaler every day if I feel fine?
Yes. It works by reducing inflammation over days to weeks, so it does nothing during an attack and only protects if taken daily. Using it only when unwell is the commonest reason controller treatment fails.
Why do I need to rinse my mouth after my inhaler?
To prevent oral thrush and hoarseness from steroid deposited in the mouth and throat. Rinse, gargle and spit out after each dose. Using a spacer reduces the deposit further.
How do I use an inhaler correctly?
With an aerosol inhaler, breathe in slowly and deeply while pressing, then hold for ten seconds. With a dry powder inhaler, breathe in hard and fast, because the device needs that force to break up the powder. A spacer roughly doubles the dose reaching the lungs from an aerosol.
When is an asthma attack an emergency?
When you cannot complete a sentence, the reliever is not helping, lips look blue, there is drowsiness or confusion, or the wheezing has stopped while breathing is still difficult. Sit upright and take one reliever puff every 30 to 60 seconds up to ten while help is on the way.
Why is a quiet chest worse than wheezing?
Because wheezing is the sound of air forcing through a narrowed airway. When the narrowing becomes severe enough, too little air moves to make any sound. A silent chest during a struggle to breathe is a sign of a life-threatening attack, not of improvement.
Can I take ibuprofen if I have asthma?
Roughly one in ten adults with asthma reacts to aspirin and NSAIDs, and the risk is much higher in those who also have nasal polyps and a reduced sense of smell. Reactions can be severe. Check with a doctor first; paracetamol is generally tolerated.
Are there side effects to montelukast?
It carries a boxed warning about nightmares, vivid dreams, agitation, low mood, aggression and suicidal thoughts, including in children with no psychiatric history. These usually appear in the first weeks and resolve on stopping, so any change in mood or behaviour should prompt advice.
Are asthma inhalers safe in pregnancy?
Yes, and uncontrolled asthma is considerably more dangerous to a pregnancy than the medicines are. Controller treatment is continued rather than reduced, and attacks are treated promptly, including with oral steroids where needed.
