I have lost the dosage and I do not know how many times a day I have to give and how many should be in the syringe.

The frequency of administration and dosage of the drug Augmentin is always selected individually for each patient - not only for weight, but also for a specific disease, therefore none of us will be able to reproduce it. It is not enough to take the drug only as directed in the leaflet. The dosage of the drug should be marked on the prescription - you can reproduce it by entering the child's prescriptions on the Patient's Online Account, calling the pharmacy where you filled the prescription or the clinic where the visit took place, or contacting the doctor who listened to the child: https://www.gdziepolek.pl/blog/jak-telefoniczne-otrzymac-recepte-i-zwolnienie-lekarskie
