Hello, Fuzi Lizhong Pill, Baizhi Dihuang Pill and Cefalexin cannot be taken at the same time. Fuzi Lizhong Pill warms the middle warmer and strengthens the spleen, in which Fuzi is a little hot, while Baizhi Dihuang Pill nourishes yin and tonifies kidney, among which Cortex Phellodendri and Rhizoma Anemarrhenae have strong heat-clearing effects, and their properties are opposite, so they should not be taken at the same time. But Fuzi Lizhong Pill or Baizhi Dihuang Pill can be taken together with Cefalexin, before meals with Chinese patent medicine and after meals with western medicine.
