Asthma preventers are only needed when children have symptoms
Is this true? Make your call, then see what the science says.
Short answer: No. The evidence doesn’t support this.
Preventers are usually meant to be taken as prescribed, not only when symptoms show up. Some older teens with mild asthma may have other options, but that is a decision for a doctor.

Australian health guidance says there are two main types of asthma medicine. Relievers are taken when needed. Preventers are taken as prescribed. If a child has been prescribed a preventer, it should be taken as directed. The guidance also says asthma treatment aims to prevent flare-ups, not just ease symptoms.
A 2025 review says low-dose inhaled corticosteroid is the preferred first-line treatment for children. Australian guidance adds that even children whose asthma shows up only occasionally can still have a serious flare-up that needs urgent treatment.
A 2021 guideline update for children over 6 moved away from relying on reliever-only treatment. It suggests an as-needed steroid-plus-bronchodilator option for milder asthma in children over 12. There was not enough evidence to support this for under-12s, so earlier advice stayed in place for them. A 2022 trial of a combination reliever in people 12 and over kept their regular preventer treatment going.
What it doesn’t mean
- Some children have asthma that appears only now and then, and treatment can differ for them. Do not stop or change a preventer without asking your child's doctor.
- If your child needs their reliever more than twice in a week, it may mean their asthma is not well controlled. See your doctor.
- Every child with asthma should have a written asthma action plan from their doctor. In an asthma emergency, call 000.
