Can I take medicine to strengthen the spleen and stomach after getting vaccinated?

Generally, it is safe to take medications that strengthen the spleen and stomach after vaccination. These are mostly traditional Chinese patent medicines or mild digestive aids that do not directly interfere with the vaccine's immune mechanism, nor do they affect vaccine efficacy or increase the risk of adverse reactions. If severe discomfort occurs after taking medication, or if there are unusual reactions at the vaccination site, medical attention should be sought promptly.

Medications for strengthening the spleen and stomach primarily regulate gastrointestinal function and improve digestion and absorption. Their ingredients are typically food-based herbal substances such as Chinese yam, poria, and white atractylodes, or mild digestive enzyme formulations, none of which interfere with the process by which vaccines prompt the body to produce antibodies.

Common post-vaccination side effects include fever, fatigue, and local redness or swelling—these do not compound with the side effects of spleen- and stomach-strengthening medications. In fact, appropriate use of these medications may help alleviate mild gastrointestinal discomfort that could occur after vaccination. However, drugs containing hormones or immunosuppressants should be avoided, as they may impair immune response.

When taking spleen- and stomach-strengthening medications, follow medical advice or the recommended dosage on the label to avoid overdose. After vaccination, maintain a light and easily digestible diet, avoiding spicy or greasy foods. Ensure adequate rest and avoid strenuous exercise to support the body in simultaneously building immunity and regulating gastrointestinal function.
