What will you recommend for pain in a four-year-old with a long expiration date after opening?

In children, liquid medicines with paracetamol or ibuprofen are generally used to combat pain. Many analgesic suspensions after opening should be used up to 3 months. Some suspensions with ibuprofen can be used after first opening up to 6 months, for example, Ibum, Ibunid, Nurofen, Ibuprom for Children, Mig. In the case of paracetamol syrups, some products have a shortened date after opening, but sometimes we will only find the information "do not use this medicine after the expiry date stated on the bottle and on the carton", which is understood as the possibility of using until the end of the expiry date. In this case, if you care about the possibility of longer use, you should make sure directly in the selected pharmacy what is the validity of the drug being purchased. Information about the possibility of using the medicine after opening should always be confirmed by reading the messages on the packaging or in the leaflet, as the composition of the medicines may change over time and may also depend on the product variant. If the pains in the child recur and are undiagnosed, then the cause should be investigated by the pediatrician.
