What should you know about inhaled steroids for asthma?

The medicine is breathed directly into the airways, where it reduces inflammation that contributes to narrowing, mucus, cough, and wheeze. It is usually a controller rather than a quick fix. A separate reliever may be needed for sudden symptoms, following your personal plan. Asthma symptoms can resemble those of other conditions, so persistent chest tightness or wheezing deserves a clinical review instead of repeated self-treatment.

Take each dose at the prescribed time and ask for a technique demonstration with your specific inhaler. A spacer may improve delivery for some devices. Rinse your mouth and spit after use, and report hoarseness, mouth soreness, or white patches. Keep a spare only if your clinician recommends it, check the device counter, and arrange reviews before changing the treatment. Avoid sharing inhalers.

Seek emergency care for severe breathlessness, blue or grey lips, inability to speak normally, collapse, confusion, or symptoms that do not improve with the prescribed rescue plan. Contact your asthma team when symptoms are becoming more frequent, disturb sleep, or limit exercise despite regular treatment.

Ask whether your inhaled steroid is a preventer, how to recognise poor control, whether a spacer is suitable, and how side effects will be monitored during follow-up.
