👉 An expired fluid refers to a substance, typically a medication or a medical solution, that has lost its effectiveness due to the expiration date on its packaging. This date is usually set by the manufacturer based on rigorous testing to ensure the product's safety and efficacy. When a fluid is expired, it may no longer contain the active ingredients necessary to treat or prevent the condition it was designed for, and in some cases, it could even contain harmful substances. It's crucial to use only products that have not expired to avoid potential health risks and ensure proper treatment.
