Looked it up on wikipedia real quick,
Sensory neuropathy typically develops at doses of pyridoxine in excess of 1,000 mg per day, but adverse effects can occur with much less, so doses over 200 mg are not considered safe.[34] Symptoms among women taking lower doses have been reported.[35]
Your dosing schedule seems fine. B6 is water soluble so unless you're taking more than 200mg daily, as the quote says, you'll just urinate it out.
