Unisom and B6 for Hyperemesis Gravidarum

NVP Counsellor
Date: 2007-02-01

Question:
I am in my 6th week of pg. I began the preemptive treatment of b6, then as soon as I found out I was pg, I started taking unisom, too. Symptoms have been manageable, but are increasing. I had severe HG last time (4 years ago), and wondered what the maximum amount of unisom/b6 is for the day. Thanks and God bless you for your work.

Answer:
To our knowledge, no studies have been conducted to determine the set maximum dose of Unisom and B6. However studies that have been carried out on Unisom at 75mg/day and vitamin B6 up to 200mg/day, have not found increased risk for birth defects or any other adverse effects on the fetus.
