Summary

This study looked at whether adding metformin, a diabetes medicine, to standard antibiotics for tuberculosis (TB) is safe and tolerable for people also living with HIV. 112 adults with both HIV and TB took either standard TB drugs alone or with metformin for 11 weeks. Researchers monitored side effects, how fast the infection cleared, and lung function.
