Stones causing vomiting can be treated with intravenous pain injections, anti-emetic medications, and in severe cases, surgery. 1. Intravenous painkillers: When stones cause vomiting, intramuscular injections of diclofenac sodium, pethidine hydrochloride and other medications can be given to relieve the pain, and the symptoms of vomiting will be relieved as well. 2. Taking antiemetic drugs: If the pain is not obvious, you can take antiemetic drugs such as domperidone tablets and metoclopramide to treat the vomiting caused by stones. 3. Surgery: If the use of painkillers and antiemetic drugs are ineffective, surgery is needed to remove the stones to relieve the pain and vomiting symptoms. Patients should drink more water, urinate more often, and exercise properly to promote the discharge of stones, and in serious cases, surgery can be used to remove the stones. If you have symptoms of vomiting, you should go to the regular hospital in time, under the guidance of the doctor, to avoid the deterioration of the condition.
