Storage Requirements for Salbutamol and Budesonide Nebules
Patients do not need to refrigerate salbutamol or budesonide nebules—both should be stored at room temperature (20°C to 25°C or 68°F to 77°F) and protected from light. 1
Budesonide Nebule Storage
Budesonide inhalation suspension must be stored upright at controlled room temperature and protected from light. 1 The FDA labeling provides specific guidance:
- Store at controlled room temperature 20°C to 25°C (68°F to 77°F) 1
- Keep ampules in their aluminum foil envelope to protect from light 1
- Once the foil envelope is opened, unused ampules have a shelf life of only 2 weeks when returned to the protective envelope 1
- Any opened ampule must be used promptly and cannot be saved 1
- Do not freeze 1
- Keep out of reach of children 1
Salbutamol Nebule Storage
Salbutamol nebules should be stored at room temperature and do not require refrigeration. While the provided guidelines do not specify exact storage temperatures for salbutamol, the British Thoracic Society emphasizes that drugs should be put into the nebulizer immediately before use as they no longer contain preservative. 2
Critical Storage Pitfalls to Avoid
Never refrigerate or freeze these medications as this can affect drug stability and efficacy. 1 The most common storage errors include:
- Leaving opened budesonide ampules exposed to light for extended periods 1
- Attempting to save partially used ampules for later use 1
- Storing medications in bathrooms or other humid environments (though not explicitly contraindicated, room temperature storage in dry conditions is optimal)
- Keeping opened foil envelopes beyond the 2-week shelf life for budesonide 1
Practical Handling Instructions
Drugs should be added to the nebulizer chamber immediately before each treatment session. 2 This practice prevents:
- Crystallization in the residual fluid 2
- Growth of micro-organisms 2
- Drug degradation from prolonged exposure to air and light
For budesonide specifically, gently shake the ampule using a circular motion before use. 1 This ensures proper suspension of the medication for optimal nebulization.
