Dischem - Pharmacists are not giving us enough information on table labels

Dis-Chem Pharmacists are not giving us enough information on how to take our medication and not writing enough details on the label. My Partner are prescribed to take Anti biotics , he is leaving in Mosselbay and i live in Cape Town, he bought his A.B in Mosselbay and i bought mine at The Dis-Chem in Table Bay Mall on Wednesday 03-02-2021, on his tables label it was stated that he shouldn't take dairy, while on cation was written. I have been taking the A.B for the past 2 days and i would eat All Brans and 250 ml of Milk every morning before taking my Table, as a result i have been having a running tummy, i still currently. i don't know what to do, as i spend my day and night in the toilet. i am so dehydrated and drained. I need feedback on this matter, why are we not given enough info on the tables labels to avoid my present state,.?
