Name a common side effect associated with INH.

Isoniazid (INH) is an antibiotic commonly used to treat tuberculosis, and one of the notable side effects associated with its use is hepatotoxicity. This condition refers to liver damage that can occur as a result of medication-induced toxicity. The liver processes many drugs, and isoniazid can produce potentially harmful metabolites that lead to inflammation or damage to liver cells, which may be particularly pronounced in individuals with pre-existing liver disease, alcohol use, or those on concurrent hepatotoxic medications.

Monitoring liver function tests is essential for patients on INH to catch any early signs of hepatotoxicity, as it can progress to more serious conditions like hepatic failure if unaddressed. Understanding the risk of hepatotoxicity is crucial for healthcare providers when prescribing INH, ensuring that patients are appropriately monitored, educated on signs of liver injury, and managed effectively throughout their treatment course.

Other side effects associated with INH, such as gastrointestinal disturbances, dermatologic reactions, and cardiovascular issues, are pertinent to patient care but do not carry the same level of serious risk for long-term damage as hepatotoxicity does.
