With the expansion and convergence of the HIV and TB epidemics worldwide, clinicians will increasingly will be called to manage and treat co-infected patients. TB and HIV medications have overlapping and additive toxicities that can complicate therapy. Additional clinical challenges include choice of optimal first and second line antiretroviral therapy, appropriate timing of antiretroviral initiation, management of immune reconstitution disease, and TB diagnosed after initiation of HIV therapy. Despite the complexities presented by co-infection, many programmes have integrated care and are successfully treating patients with both HIV and TB.
