SABA reliever dosing
Routine as-needed SABA use; acute attacks require a separate age-specific exacerbation protocol.
Last reviewed January 5, 2026
Contraindications
- Avoid in known salbutamol hypersensitivity.
- Do not rely on frequent reliever-only use as a substitute for controller optimization.
- Reassess risk in patients with severe tachyarrhythmia or medication-triggered adverse effects.
Dosing
Salbutamol MDI (100 mcg/puff)
- Starting dose
- 1-2 puffs every 4-6 hours as needed
- Typical titration / target
- Use spacer when possible; reassess if frequent use
- Monitoring / notes
- More than 2 reliever doses/week suggests inadequate control; this is not acute-exacerbation dosing.

Renal and hepatic considerations
- Routine inhaled reliever dosing usually does not require renal or hepatic adjustment.
- In severe comorbidity, monitor for systemic beta-agonist adverse effects when use becomes frequent.
- Review interacting medications that may increase tachycardia or electrolyte risk.
Pregnancy and lactation cautions
- Maintain maternal respiratory stability with individualized treatment planning in pregnancy.
- Use the minimum effective reliever exposure while optimizing controller strategy.
- During lactation, confirm current compatibility guidance and monitor if frequent dosing is needed.
Monitoring checkpoints
- Teach spacer technique and inhaler priming.
- Track reliever frequency; more than 2 doses/week signals inadequate control (a dose may include more than one puff).
- Review action plan and when to seek urgent care.
Stop or escalate criteria
- Escalate urgently for worsening breathlessness, poor response to reliever, or hypoxia signs.
- Escalate controller therapy if reliever use increases.
- Stop routine self-escalation and reassess promptly if palpitations, tremor, or chest discomfort become significant.
