What is a critical storage instruction for Symbicort after opening?

The critical storage instruction for Symbicort after opening is to use it within 90 days. This guideline is essential because the effectiveness of the medication diminishes over time once the inhaler is opened and exposed to the environment. The 90-day recommendation helps ensure that patients receive the full therapeutic benefit from the medication, as its potency may decline due to factors like humidity and exposure to air.

Maintaining this time limit helps prevent the use of a potentially less effective inhaler, which could lead to inadequate control of the patient’s respiratory condition. Therefore, it is crucial for users to be aware of this timeframe for optimal efficacy.
