Isoniazid commonly causes dose-related peripheral neuropathy, which results from the depletion of pyridoxine in the presence of the drug. The neuropathy is usually.
Pyridoxine given in large doses is thought to selectively destroy the large-diameter peripheral sensory nerve fibers, leaving motor fibers intact. Pyridoxine overdose has been used in the scientific community as a new paradigm of pure sensory neuropathy loss.
Isoniazid: Acute ingestion of known amount: Initial: A total dose of pyridoxine equal to the amount of isoniazid ingested (maximum dose: 70 mg/kg, up to 5 g); administer at a rate. Sensory neuropathy with axonal degeneration has been reported following a single large dose of pyridoxine (10 g) administered intravenously.
Isoniazid typically causes a sensory peripheral neuropathy which presents with burning and numbness of the extremities. In a few cases, sensory symptoms may progress rapidly with the development of ataxia and motor weakness. Isoniazid acts as a competitive inhibitor of pyridoxine (B6), making its biologically active form.
Among antituberculosis agents, isoniazid and ethambutol (Myambutol) are well known for inducing peripheral neuropathy.10 Isoniazid induces a mixed sensorimotor peripheral neuropathy.
