What should I do if I took metronidazole and then consumed fermented rice (jiuniang)?

Glutinous rice wine (also known as "Laozao") is a sweet rice wine made from fermented glutinous rice mixed with yeast. Generally, consuming Laozao after taking metronidazole may cause discomfort. Treatment may involve monitoring symptoms, drinking more water, inducing vomiting, taking medication, or seeking prompt medical attention. Specific details are as follows:

1. Monitor Symptoms

Metronidazole is an antibacterial and antiparasitic medication. Alcohol-containing products such as Laozao are typically not recommended during treatment, as the alcohol in Laozao may interact with the drug and cause adverse reactions. If only a small amount has been consumed and no obvious discomfort occurs, immediate treatment may not be necessary; however, close observation of symptoms is advised.

2. Drink More Water

Patients can drink moderate amounts of warm water to promote excretion, which may help accelerate alcohol metabolism and reduce the risk of adverse reactions.

3. Induce Vomiting

If Laozao is consumed after taking metronidazole, a reaction between the drug and alcohol may occur. In such cases, throat stimulation to induce vomiting may help expel the ingested substances, reducing alcohol absorption and metabolism, thereby minimizing damage to the body.

4. Take Medication

Under medical guidance, medications such as vitamin C and vitamin B6 may be used to alleviate symptoms. These vitamins can accelerate alcohol metabolism in the body, helping to reduce the interaction between alcohol and metronidazole and effectively relieve discomfort.

5. Seek Prompt Medical Attention

If a large amount has been consumed and symptoms such as severe vomiting or difficulty breathing occur, immediate medical evaluation is necessary. Under a doctor's supervision, gastric lavage may be performed to help alleviate symptoms.

Patients are advised to pay attention to medication contraindications in daily life and avoid alcohol consumption while taking medications to prevent adverse effects.
