I swallowed by mistake a medical disinfectant called Zafarin Forte about a teaspoon. I thought it was cough medicine. I drank as much water and milk as I could. This was at midnight at 10 am my throat is sore and red painful to a degree but not extremely so. Within 20 mins of swallowing the disinfectant I began having watery stools and minor cramps. Is there anything else I should be doing treatment wise?
