How long is it good after opening Hasco Forte with paracetamol?

As I understand it, the question is about children's suspension. According to the leaflet of the suspension Paracetamol Hasco Forte - "after the first opening of the package, the drug retains stability for 12 months." During this time, it should be stored below 25°C. At the same time, remember not to use this medicine after the expiry date stated on the package. The expiry date refers to the last day of the given month. For example, if a suspension valid until the end of 2023 is opened today (19.03.2023), it can only be used until the end of the year, not for twelve months.
