How long can ibuprofen suspension be stored after opening?

Generally, after opening, ibuprofen suspension can be stored for up to one month under proper storage conditions. If not stored as required, its shelf life may shorten, and it might deteriorate prematurely and thus should not be used further. Detailed explanations are as follows:

Ibuprofen suspension is commonly an oral liquid formulation. After opening, it may become contaminated with microorganisms or lose efficacy due to exposure to air and potential evaporation of ingredients. If the bottle cap is tightly closed after each use and the suspension is stored in a cool, dark place, its quality can be effectively maintained for up to one month, during which it can still be safely used. However, if stored in high temperatures, humid conditions, or under direct sunlight, the medication may show signs of deterioration, such as discoloration, cloudiness, or unusual odor, and should no longer be used even if less than a month has passed. Improperly stored ibuprofen suspension may not only lose potency but also develop bacterial growth, which could cause gastrointestinal discomfort, such as nausea and vomiting, after consumption.

In daily use, it is recommended to label the bottle with the opening date after the first use to keep track of the storage duration. Avoid contact between the bottle opening and unclean utensils to prevent contamination. If the suspension remains unused after one month, it should be discarded promptly and not consumed again, to ensure both the safety and effectiveness of the medication.
