Foster Inhaler Storage Requirements

Foster inhaler does NOT need to be refrigerated – it should be stored at room temperature below 25°C (77°F) and protected from excessive heat and direct sunlight 1.

Key Storage Instructions

Based on the FDA drug label, Foster inhaler requires the following storage conditions 1:

  • Store below 25°C (77°F) – room temperature storage is appropriate
  • Avoid excessive heat and direct sunlight – keep in the outer carton for protection
  • Keep cap on when not in use – maintains product integrity
  • Do not refrigerate – there is no refrigeration requirement for this product

Important Clarification

You may be confusing Foster with medications that do require refrigeration. The evidence shows that certain medications need cold storage (2°C-8°C), including vaccines, insulin, and some chemotherapy drugs 2. However, Foster inhaler is not among these products.

Why This Matters for Patient Outcomes

Proper storage of inhalers is critical for maintaining drug potency and ensuring effective treatment. Research demonstrates that while some inhalers can tolerate temperature variations, storing medications outside manufacturer recommendations can affect drug delivery 3. For Foster specifically:

  • Storing above 25°C may compromise the formulation
  • The product contains beclometasone dipropionate and formoterol fumarate in a pressurized metered-dose inhaler 4
  • Improper storage could potentially affect the emitted dose and therapeutic efficacy

Common Pitfall to Avoid

Do not place Foster inhaler in the refrigerator – this is unnecessary and could potentially expose it to temperatures that are too cold. Simply store it at room temperature in a cool, dry place away from heat sources and direct sunlight 1.
