What should the facility staff do after discovering adverse drug reactions in a patient on a DRTB regimen?

In the context of managing adverse drug reactions in a patient on a drug-resistant tuberculosis (DRTB) regimen, it is crucial for facility staff to take a comprehensive approach that includes several important steps.

First, checking for other potential causes of the adverse event is essential. Adverse reactions can arise from multiple sources, including drug interactions, other medications, or underlying patient conditions. Identifying alternative causes helps ensure that the patient receives appropriate care without attributing all issues to the anti-TB regimen prematurely.

Second, conducting liver function tests to measure serum SGPT (ALT) and SGOT (AST) levels is also a necessary action. This laboratory evaluation helps assess whether the adverse reaction might be a result of hepatotoxicity, which is a known risk with many anti-TB drugs. Monitoring liver function provides vital information that guides further treatment decisions.

Lastly, while the immediate wholesale stoppage of all anti-TB drugs may seem like a prudent choice, it is not often the best immediate course of action. Discontinuing all medications can lead to treatment interruptions and increase the risk of developing drug resistance or treatment failure. Instead, a more measured approach is typically recommended, which could involve stopping specific drugs contributing to the adverse reaction while continuing others.
