The tablet you have attached is a probiotic. It helps restore healthy bacteria in the gut, which can be useful in diarrhea, but it will not give immediate relief from loose motions. Since you already had multiple watery stools with vomiting, the most important thing right now is to prevent dehydration .take plenty of fluids, ORS, coconut water, etc.
Next Steps
If loose motions are very frequent or you are unable to keep fluids down, please visit a doctor urgently for rehydration. For symptomatic relief, you can be prescribed medicines like ORS, probiotics, and sometimes anti-diarrheal medicines, but these should be taken only after medical advice.
Health Tips
Please monitor your urine output, weakness, or dizziness. if these worsen, seek medical care immediately.
