Treatment Regimens for Latent TB Infection (LTBI)
Guidelines for the Treatment of Latent Tuberculosis Infection: Recommendations from the National Tuberculosis Controllers Association and CDC, 2020
Baseline Laboratory Testing
Baseline laboratory testing (measurements of serum AST, ALT, and bilirubin) are not routinely necessary
Laboratory testing at the start of LTBI therapy is recommended for patients with any of the following factors:
- Liver disorders
- History of liver disease (e.g., hepatitis B or C, alcoholic hepatitis, or cirrhosis)
- Regular use of alcohol
- Risks for chronic liver disease
- HIV infection
- Pregnancy or the immediate postpartum period (i.e., within 3 months of delivery)
Baseline testing can be considered on an individual basis, especially for patients taking other medications for chronic medical conditions.
After baseline testing, routine periodic retesting is recommended for persons who had abnormal initial results and other persons at risk for hepatic disease.
At any time during treatment, whether or not baseline tests were done, laboratory testing is recommended for patients who have symptoms suggestive of hepatitis (e.g., fatigue, weakness, malaise, anorexia, nausea, vomiting, abdominal pain, pale stools, dark urine, chills) or who have jaundice. Patients should be instructed, at the start of treatment and at each monthly visit, to stop taking treatment and to seek medical attention immediately if symptoms of hepatitis develop and not to wait until a clinic visit to stop treatment.
AST or ALT elevations up to 5 times normal can be accepted if the patient is free of hepatitis symptoms, and up to 3 times normal if there are signs or symptoms of liver toxicity.

Prescription Donation Program
Clinicians and Local Public Health Agencies that have unused TB medications are able to send them to the Iowa Prescription Drug Corporation (IPDC) for certification for re-use by the Iowa TB Control Program. Once meds have been certified they are sent back to our pharmacy to be reissued by our program.
Once the form below is completed, mail it and the medications to the address in the upper right corner of the form. The form only needs to be completed once and will be kept on file at IPDC for any future donations.
