In cases of acute high doses, for example in people receiving daily doses of 2 grams of vitamin B6 per kilogram of body weight, symptoms may be irreversible and may additionally cause pseudoathetosis.In the immediate 2–6 weeks following discontinuation of vitamin B6, patients may experience a symptom progression before gradual improvement begins. This is known as coasting and is encountered in other toxic neuropathies. A vitamin B6 substance dependency may exist in daily dosages of 200 mg or more, making a drug withdrawal effect possible when discontinued. See also
