Is INH safe for use in pregnant women?

The statement that INH (isoniazid) can be used in pregnant women but only if absolutely necessary reflects the careful consideration needed when prescribing this medication during pregnancy. INH is an important antibiotic for treating tuberculosis, and while it does have potential risks, especially concerning fetal health, its benefits may outweigh those risks in certain scenarios.

The use of INH during pregnancy should be evaluated on a case-by-case basis. If a pregnant woman has active tuberculosis, the risk of untreated TB to both the mother and the fetus may be significant, and treatment with INH may be warranted, thus making its administration necessary despite potential risks. Healthcare providers must weigh these factors carefully and monitor the patient closely if INH is prescribed.

In contrast, the other options present more absolute stances that do not account for the clinical context surrounding tuberculosis treatment in pregnant women. Therefore, the nuanced approach conveyed by the correct answer is essential for safe and effective care.
