Since your patient cannot tolerate oral medications and is vomiting frequently, she is at risk of dehydration. Please temporarily pause oral intake, including the probiotic and cough syrup, as forcing them may trigger more vomiting. I highly recommend consulting a doctor or visiting a clinic immediately. Since she cannot keep oral medicines down, she may require an injection or intravenous (IV) therapy to control the vomiting and restore hydration. Once the vomiting stops, oral rehydration solutions and her prescribed medicines can be gradually restarted in small, frequent sips under medical guidance.
