12-Week INH-RPT Regimen for Treatment of Latent TB Infection
In December 2011, the Centers for Disease Control and Prevention (CDC) published recommendations for an additional option for the treatment of latent TB infection (LTBI) in some individuals. This new regimen consists of 12 weekly doses of isoniazid (INH) and rifapentine (RPT). It is intended for use in certain high-risk patients and must be administered as Directly Observed Therapy (DOT) by local health departments. Links to CDC materials about this regimen are listed below.
MDH will supply medications for this regimen through its free TB medications program for patients who meet eligibility criteria and for whom a specific plan is in place to provide monthly physical examinations at a clinic and DOT by the local health department. Local health departments in Minnesota may vary in their ability to provide this service.
