Which element should be avoided while taking isoniazid?

• A. Alcohol
• B. Caffeine
• C. Salt
• D. Sugar

Answer: (A)

Avoiding alcohol is important because isoniazid can cause liver irritation and, when combined with alcohol, the risk of hepatotoxicity increases. The liver already has to metabolize isoniazid, and alcohol adds extra strain and can enhance the formation of harmful metabolites, raising the chance of hepatitis or liver injury. This protective step is especially crucial for those with preexisting liver issues or slower drug metabolism. Caffeine, salt, and sugar don’t carry the same well-established liver interaction with isoniazid, so they’re not required to be avoided for this reason.
