Introduction
Under normal circumstances, ibuprofen suspension can be stored for 1-3 months after opening. Before using the stored ibuprofen suspension, check whether the medication has changed color, become cloudy, developed sediment, or has an unusual odor; if any abnormalities are observed, discard it immediately. The suspension should be thoroughly shaken before each use to ensure uniform drug concentration. When administering to children, the dosage must strictly follow the recommendations based on their age and weight.
Generally speaking, after opening, ibuprofen suspension can be stored for 1 to 3 months. Detailed analysis is as follows:
If the ibuprofen suspension is stored sealed at room temperature after opening, and the room temperature remains around 20-25℃ without exposure to direct sunlight, high temperature, or humid conditions, it can be stored for about 1 month. Microorganisms easily proliferate at room temperature, and the drug components may degrade slowly over time. Using the medication within one month helps ensure its effectiveness and safety; beyond that, there may be a risk of reduced efficacy or deterioration.
If the ibuprofen suspension is immediately stored sealed in the refrigerator's chill compartment after opening, and the refrigerator is free of odors and cross-contamination from other easily spoiled foods, the cold environment can inhibit microbial growth and slow down the degradation of the drug components. In this case, it can be stored for 3 months. The low-temperature environment provides stable storage conditions for the medication, extending its effective shelf life; however, it is important to ensure that the container is promptly sealed and returned to the refrigerator after each use.
Before using the ibuprofen suspension during the storage period, check whether the liquid has changed color, become cloudy, developed sediment, or emits an unusual odor. If any abnormalities are observed, discard it immediately. The suspension should be thoroughly shaken before each use to ensure uniform drug concentration. When administering to children, strictly follow the dosage recommendations based on their age and weight, and do not arbitrarily increase or decrease the dose.
