Introduction
Lianhua Qingwen Granules generally have a shelf life of 2 to 3 years. They should be stored sealed in a cool, dry place, away from high temperatures and humid environments. Before use, carefully check the expiration date indicated on the packaging and verify the production date. If the medication shows any abnormalities such as clumping, discoloration, or unusual odor, it should be discarded regardless of whether it is within the shelf life, to avoid potential health risks after consumption.
Generally, the shelf life of Lianhua Qingwen granules is 2–3 years, but the exact duration should be based on the labeling on the packaging. Improper storage can shorten the shelf life. If in doubt, it is recommended to check the package instructions for confirmation. Detailed analysis is as follows:
Lianhua Qingwen granules purchased through正规 channels will have the production date and shelf life clearly labeled on the packaging. Most products have a shelf life of 2 years, while some manufacturers’ products may last up to 3 years—this refers to the effective period under specified storage conditions.
If stored improperly—for example, in damp, high-temperature environments, under direct sunlight, or if the packaging is damaged leading to moisture exposure—the medicine may absorb moisture or clump. Even within the labeled shelf life, such conditions could result in reduced efficacy or changes in composition, significantly shortening the actual effective period. These medications are not recommended for use.
For storage, keep the product sealed in a cool, dry place away from heat and humidity. Always carefully check the expiration date on the packaging before use and verify the production date. If the medication shows abnormalities such as clumping, discoloration, or an unusual odor, it should be discarded regardless of whether it is within the labeled shelf life, to avoid potential health risks after consumption.
