Patients need to take precautions with isoniazid. This medication is not safe for use in patients with active liver disease. In addition, those with a history of hepatitis should not take it either. Patients should review their medical history with their doctor before starting this medication. Points of note include having a history of kidney disease, diabetes, HIV, nerve issues, liver disease, or malnourishment.

Their doctor will also need to know about the patient's alcohol use and if they have ever used injected drugs. Patients thirty-five or older need to have their liver enzymes checked before starting this medicine. In addition, patients must take this medication on an empty stomach. Ideally, they should take it one to two hours before a meal.
