What are common signs of peripheral neuropathy in patients taking INH?

Numbness, tingling, or burning sensations are hallmark signs of peripheral neuropathy, especially in the context of medication like isoniazid (INH), which is used to treat tuberculosis. This class of symptoms occurs due to nerve damage often associated with deficiencies in certain vitamins, particularly vitamin B6 (pyridoxine), which INH can deplete in the body. Patients may report these sensations as they experience changes in nerve function, with the most commonly affected areas being the hands and feet.

These symptoms reflect the dysfunction of the peripheral nervous system, leading to a variety of sensory disturbances. Recognizing these signs early is crucial for healthcare providers so they can manage and possibly mitigate the negative effects of INH on nerve health through dietary supplementation or alternative therapies.

The other options presented do not directly relate to the specific manifestations of peripheral neuropathy associated with INH use. While joint pain, headaches, dizziness, muscle weakness, and cramps can occur for various reasons, they are not specific indicators of peripheral neuropathy resulting from the use of INH.
