Can an 8-month-old baby with G6PD deficiency (favism) take Jianwei Xiaoshi Pian (a traditional Chinese medicine for promoting digestion and strengthening the stomach)?

An 8-month-old infant with favism (glucose-6-phosphate dehydrogenase deficiency, or G6PD deficiency) may generally take Jianwei Xiaoshi Pian (a traditional Chinese medicine for promoting digestion and strengthening the stomach), but it must be administered strictly under a physician’s guidance. Self-medication or excessive dosing should be avoided to prevent adverse effects on the infant’s health.

Favism is a genetic disorder caused by deficient activity of glucose-6-phosphate dehydrogenase (G6PD) in red blood cells. Ingestion of fava beans or fava bean–containing products commonly triggers acute hemolytic anemia—hence the name “favism.” It predominantly affects boys under age 10. Clinical manifestations during an acute episode typically include vomiting, jaundice, nausea, anorexia, and dizziness. Without prompt medical intervention, severe hemolysis may become life-threatening. Therefore, once favism is diagnosed, fava beans and related products must be discontinued immediately to prevent hemolytic crises and associated complications.

During treatment, ensure the infant gets adequate rest, drinks plenty of warm water, and monitor their mental status closely. Seek immediate medical advice if any signs of discomfort arise. For formula-fed infants, avoid preparing overly concentrated formula. For breastfed infants, mothers must strictly avoid consuming fava beans or fava bean–derived products.
