Neurological symptoms include headache, dizziness, occasionally abnormal sensation, numbness of limbs, ataxia, multiple neuritis, etc. Large doses can cause convulsions. A few cases have occurred with urticaria, flushing, itching, cystitis, difficulty urinating, metal taste in the mouth, and leukopenia, all of which are reversible and recover spontaneously after discontinuation of the drug.
