Vitamin B6

NVP Counselor
Date: 2004-12-09

Question:
I have read that taking a vitamin B6 supplement will help with NVP. Is this true and what are the risks in doing so? Do you have to get the prescription from your doctor that is a time release vitamin/drug or can you just take an over the counter B6 vitamin?

Answer:
Diclectin, the time release medication for NVP, contains 10 mg of Vitamin B6 and 10 mg of doxylamine succinate. Safety of the medication, i.e., both components, has been well established by numerous studies over its 40 years of use. One of our studies confirmed the safety of up to 8 Diclectin per day, i.e., up to 80 mg of Vitamin B6.

For mild symptoms, Vitamin B6 can be tried alone. Our suggestion is to use 25 mg once, twice or 3 times per day. This can be bought over the counter at your local pharmacy.
