Can I still use Merrill Ibuprofen Suspension in the refrigerator? The answer to this question depends on your use and the expiration date of the medication. If you have bought Merrill, also known as Ibuprofen Suspension, and have not opened the package and have kept it in the refrigerator, it is perfectly fine to use it, it does not matter, just shake this suspension well before you use it, and take it according to the child’s kilograms of body weight out of the exact scale. If you buy Merrill that has been used and then put it in the refrigerator, this is the time to look at how long it has been in the refrigerator. If it has been in the refrigerator for a month, it can still be used, that is, at this time the ibuprofen suspension may not have been contaminated by bacteria or fungi, and can still play a fever, pain relief, anti-inflammatory effect. However, if the ibuprofen suspension has been used once, that is, after opening the lid, and then put the lid back on and put it in the refrigerator for more than six months, it is not recommended to use it again, because long-term refrigerator storage may lead to mold or bacterial contamination of these suspensions, which may be risky if taken again.
