Are there any specific dietary restrictions while taking INH?

While taking isoniazid (INH), there are indeed specific dietary considerations to keep in mind, particularly regarding alcohol consumption. One of the significant guidelines is that individuals on INH should avoid alcohol. This is important because isoniazid can affect liver function, and combining it with alcohol increases the risk of hepatotoxicity. Therefore, limiting or completely avoiding alcohol helps minimize the potential for liver damage while on the medication.

The other options mention different dietary restrictions that are not applicable. Carbohydrate intake, dairy products, and fruits and vegetables are not specifically restricted while taking INH. Maintaining a balanced diet, including these food groups, is generally encouraged, as long as the patient's overall health allows for it. However, the avoidance of alcohol remains the most critical dietary restriction for patients undergoing treatment with isoniazid.
