If the patient consumes a small amount of the tasteless beverage, for younger patients with no obvious primary underlying disease or patients with good immunity, no special treatment is necessary and the patient’s condition can be observed. However, for older patients with obvious primary underlying diseases, once the patient has consumed the tasteless beverage, he/she should go to the hospital for the next step of treatment by drinking large amounts of saline and vomiting it by picking his/her throat. If the patient has obvious nausea, vomiting, acid reflux, heartburn and other symptoms, symptomatic medications such as omeprazole, rabeprazole and other drugs can be used for gastrointestinal protection, and injectable vitamin C and other drugs can be applied for symptomatic treatment. If the patient has significant abdominal pain, mannitol injection can be applied for enema to completely expel toxic substances that are not completely and thoroughly absorbed in the intestinal tract.
