TB Drug and Skin Testing Solution Shortages
Most TB control programs in the United States have experienced trouble accessing supplies used in the treatment and diagnosis of latent TB infection (LTBI) and TB disease. Shortages of TB drugs and skin testing solution (PPD) used for TB diagnosis, care, and prevention have been reported over the past decade; however, reports of shortages have increased within the past several years. Interruptions in supplies of drugs used for treating infectious diseases pose a significant public health threat by delaying or even preventing some types of patient care allowing disease to spread, and contributing to the development of drug resistance.
Results of Shortages on Patient Care
Results of shortages on patient care include
- Delays in treatment or testing
- Rationing or restriction of drugs
- Using less effective alternative drugs for treatment
- Occurrence of medication errors and adverse events related to using alternative drugs
- Increases in drug costs
- Increases in TB program costs
- Increases in TB program staff time dedicated to drug procurement
Reasons for Shortages
Shortages occur for many reasons, including
- Problems with manufacturing (most common)
- Delays in manufacturing or shipping
- Shortages of active pharmaceutical ingredients (API)
- Imbalances in supply and demand
What is CDC Doing about the Shortages?
CDC is working closely with state and local TB control programs, the U.S. Food and Drug Administration (FDA), and pharmaceutical companies to try to prevent the interruptions to TB supplies. Actions taken by CDC include
- Consulting with TB programs when shortages are identified
- Sharing information about drug availability with TB programs
- Providing evidence of impact of drug shortages and increasing drug costs
- Collaborating with FDA to reduce impact of drug shortages
- Releasing health alerts to advise TB programs on options for patient care during shortages
Current Status of Shortages
