Brief Answer:
No adverse interaction between the two

Detailed Answer:
Hello,

Welcome and thanks for your query.
Both Keflex and Bactrim are antibiotics and Keflex is likely to have better action on the skin infections than Bactrim. There is no need to change Keflex or add Bactrin unless any culture done on the pus showed that the bacteria is more sensitive to Bactrim than Keflex. There is no adverse interaction between Keflex and Bactrim or with any of the other medicines you are on.
Best wishes,
