What medicine should I take for a quick recovery from nausea and vomiting caused by a cold?

Nausea and vomiting caused by a cold can generally be relieved with medications such as domperidone, Huoxiang Zhengqi preparations, vitamin B6, metoclopramide, and montmorillonite powder. Specific details are as follows:

1. **Domperidone**: A prokinetic agent that accelerates gastric emptying, improving indigestion and nausea associated with the common cold. By enhancing gastrointestinal motility, it reduces discomfort caused by food retention in the stomach. It acts quickly and is suitable for conditions during a cold involving poor appetite, bloating, and nausea.

2. **Huoxiang Zhengqi Preparations**: These have effects of relieving exterior symptoms, resolving dampness, regulating qi, and harmonizing the middle. They are appropriate for colds caused by exposure to wind-cold externally and internal injury from damp stagnation, particularly when accompanied by nausea. They help alleviate vomiting and diarrhea due to gastrointestinal dysfunction, and also provide supportive relief for dizziness and chest tightness associated with colds. With mild properties, they are suitable for various body types.

3. **Vitamin B6**: Involved in metabolic processes, it helps regulate gastrointestinal function and reduce nausea triggered by colds. It is especially useful for mild nausea resulting from medication irritation or viral effects during a cold. It has minimal side effects, provides rapid symptom relief, and supports recovery.

4. **Metoclopramide**: A central antiemetic with strong anti-nausea and antivomiting effects. It is suitable for frequent nausea and vomiting caused by colds. It suppresses the vomiting center, relieves spasms of gastrointestinal smooth muscles, and significantly improves severe vomiting symptoms. It should be taken according to prescribed dosages to avoid overdose.

5. **Montmorillonite Powder**: Although primarily an antidiarrheal, it protects the gastrointestinal mucosa and reduces mucosal irritation caused by viruses or medications. It is indicated when nausea occurs alongside diarrhea during a cold. It adsorbs harmful substances in the intestines, alleviates gastrointestinal discomfort, indirectly reduces nausea, and aids in mucosal repair.

Before taking any medication, ensure there is no history of drug allergy. Follow instructions on the label or as directed by a healthcare provider, and avoid blindly combining multiple drugs. During a cold, maintain a light and easily digestible diet, avoid greasy and cold foods that may irritate the gastrointestinal tract, and drink plenty of warm water to stay hydrated.
