How these guides are written and reviewed →
A Spiromax is a dry-powder inhaler that looks like a puffer. Opening the mouthpiece cover fully loads a dose automatically — there is nothing to twist or press. Then you breathe in forcefully and deeply.
DuoResp Spiromax (budesonide / formoterol) may be prescribed as a preventer only, or as both preventer and reliever (maintenance-and-reliever therapy, or MART). The two regimens are not interchangeable, and extra doses are only safe if MART has been prescribed for you. Your written action plan states which applies — if it does not, ask before taking an extra dose.
Examples of this type
Different medicines come in this device. Common examples include:
- DuoResp Spiromax (budesonide / formoterol)
Brand names are examples only and availability changes — always go by the name on your own inhaler and your prescriber's instructions.
How to use it — step by step
Getting the best from it
- One open = one dose; opening and closing repeatedly wastes medicine.1,2
- Do not cover the air vents with your fingers or lips.
- If also used as a reliever, follow your written action plan.
Looking after your inhaler
Wipe the mouthpiece with a dry tissue only; keep it dry. Watch the dose counter.
Most people lose some accuracy over time.3,4 We can check your inhaler technique at your appointment.
