Acidolac Baby, opinions and questions

Good morning. I'm looking for a probiotic that is a medicine, not a dietary supplement, that will fully protect adults in the event of a trip to Egypt (lactobacillus acidophilus, bifidobacterium bifidum, sacharomyces boulardi strains). Similarly, we would like to protect our son (1.5 years old). Best regards

Ceclor 250 (100ml) husband rushed and added water to the mark on the bottle instead of measuring the pinch. Is the antibiotic made in this way correct? And whether you need to add water to the mark after mixing.
