What are the consequences of stopping INH treatment prematurely?

Stopping isoniazid (INH) treatment prematurely can lead to treatment failure, which is the correct understanding. INH is a first-line antibiotic used primarily in the treatment of tuberculosis (TB). It works effectively to kill the bacteria causing TB and helps prevent the development of drug-resistant strains when taken for the full prescribed duration.

When treatment is interrupted, the bacteria may not be fully eradicated, allowing them to survive and potentially multiply. This can result in a resurgence of the infection, making it harder to treat subsequently. Moreover, incomplete treatment can contribute to the development of drug-resistant TB, complicating future treatment options and public health efforts.

The other options do not align with the implications of interrupting therapy. For instance, increased energy levels and improved immune response would not necessarily result from stopping treatment; instead, patients could experience worsening health due to the uncontrolled infection. Similarly, decreased risk of side effects is misleading, as stopping treatment does not eliminate the risk of side effects experienced during therapy; it may instead allow the underlying disease to progress unchecked.
