My daughter is 4 yr old, weight roughly 14 kg , had foul smell in poo for 2 days , lost of appetite & loose motions like thrice a day .I gave her gnorm sachet day before yesterday, before sending her to school because she was playful otherwise. Yesterday morning she started vomiting and had watery motions, so I gave her5 ml of emset syrup 2mg kids bottle, I tried giving her bifilac-zn sachet later , but spit it out . After after three four motions, I felt she was fine, because she eat herself after few days.( just simple daal rice and banana half slice of bread, two slices of Apple) didn t have dinner or anything later in day though. But this morning again she has watery motions and vomit. So , my question is :- 1) what should be the dosage of emset syrup, bifilac- zn sachet? I guess it s 5ml, and 1 sachet respectively, but can it be given just once a day or every time before and after food? Also how much time gap should be given after taking emset to take bifilac- zn? 2) She has been given an appointment to take flu vaccination on Monday .( I live in UK, here this vaccination is given in school to all children because of the cold weather) can she take the vaccination if she is taking bifilac-zn sachet?
