Asthma inhalers are medications for inhalation that act directly in the bronchial tubes — where the asthma is located. A distinction is made between preparations that rapidly dilate the airways and those that permanently calm the underlying inflammation; often both are combined. Because the active ingredient reaches the lungs directly, very small amounts are sufficient — this makes the treatment effective and at the same time gentle.
Typical Areas of Use
- Asthma in adults and children
- Episodes of shortness of breath and wheezing
- Chronic cough associated with asthma
- Exercise-induced asthma
- Chronic obstructive pulmonary disease (COPD)
How It Works
- 1The diagnosis is first confirmed, usually with a lung function test and, depending on the situation, an allergy test.
- 2Your doctor puts together the treatment according to a step-by-step scheme. Adults, adolescents, and children aged 6 years and above should not be treated with a fast-acting reliever spray alone: the treatment should include an anti-inflammatory inhaled corticosteroid, because this has been shown to make severe asthma attacks less frequent. Which corticosteroid-containing reliever or maintenance therapy is suitable depends on age, symptom control, and risk of attacks.
- 3You will practice the inhalation technique directly in the surgery or pharmacy — the correct technique is crucial in determining how much active ingredient reaches the lungs.
- 4Follow-up appointments will assess how well the asthma is controlled, and treatment will be adjusted step by step — upwards or downwards.
How to Prepare
- Note the situations in which shortness of breath or coughing occurs — for example, during exertion, pollen season, or infections.
- Bring any inhalers or sprays you are already using so that your technique can be checked.
- Mention any other conditions and medications, particularly beta-blockers.
Side Effects & Risks
- Fast-acting bronchodilator sprays can temporarily cause palpitations, trembling, or restlessness.
- Cortisone-containing inhalers can promote hoarseness and oral thrush (fungal infection in the mouth) — rinsing your mouth after inhalation helps prevent this.
- With incorrect inhalation technique, too little active ingredient reaches the lungs, which can appear like treatment failure.
- Excessive use of the rescue inhaler is a warning sign of poorly controlled asthma and should be assessed by a doctor.
Pay attention to how often you need the rescue inhaler — increasing use, waking at night due to shortness of breath, or limitations in daily life are signs that the treatment should be adjusted. Rinse your mouth after inhaling cortisone-containing medications. If shortness of breath rapidly increases despite using the rescue inhaler, speaking becomes difficult, or symptoms persist for hours, seek medical help — in case of severe shortness of breath, call the emergency number 144.

Cost & Insurance
Physician-prescribed asthma inhalers are usually covered by mandatory basic insurance, as are lung function tests and follow-up check-ups — the Franchise and co-payment apply as usual. This is for guidance only, without guarantee; if in doubt, your health insurer will provide information.
Frequently Asked Questions
- What is the difference between a rescue inhaler and maintenance therapy?
- The function an inhaler has depends on the active substance and the treatment regimen. Some are used regularly as a long-term therapy, others as needed. Certain combinations of inhaled corticosteroid and a fast-acting bronchodilator (ICS/Formoterol) serve both purposes at once: treating the inflammation and providing rapid relief when needed. A purely as-needed treatment without corticosteroid is no longer recommended today.
- Is inhaled cortisone harmful?
- The inhaled amounts are very small and act almost exclusively locally in the bronchial tubes — the feared cortisone side effects from tablets practically do not occur. Untreated asthma is significantly more stressful for the body.
- Do I have to use the maintenance therapy even when I feel well?
- Yes — especially then. Being symptom-free is the effect of the treatment, not a sign that it has become unnecessary. Whether the dose can be reduced is decided by your doctor based on your progress.
- Why is inhalation technique so important?
- Only when inhaled correctly does the active ingredient reach deep into the bronchial tubes; with incorrect technique, much of it remains in the mouth and throat. Therefore, have your technique checked regularly at the surgery or pharmacy — especially when changing devices.
- Can I exercise with asthma?
- Yes, exercise is expressly encouraged with well-controlled asthma and strengthens the lungs. In the case of exercise-induced asthma, your doctor can adjust the treatment so that physical activity is well tolerated.
