In brief: See below
Isoniazid neuropathy develops in the presence of risk factors (hiv, alcoholism, diabetes, renal failure, malnutrition, pregnancy and lactation, neurotoxic medication) and manifests itself initially by burning feet.
Your doctor may also want you to take a supplemental vitamin b6 (pyridoxine) tablet daily during treatment to prevent numbness and tingling caused by low levels of this vitamin.
