Unisom and risk of addiction

NVP Counsellor
Date: 2007-01-19

I'm 8 1/2 weeks pregnant and have had severe nausea since week 5. I have prescriptions for Phenergan and Zofran. Both have worked only so-so, although I have the minimal dosages. Last night, I tried 25 mg B6 with 1/2 Unisom tab. I had virtually no night nausea- something the prescriptions didn't even do for me. Plus, I slept great. I'd like to continue the B6/Unisom combination, but I am concerned about developing a dependency on the Unisom. Do you have any information regarding Unisom dependency/addiction?

Unisom is a sedating antihistamine,that is why you slept so well. Consult your doctor about the combination of B6/Unisom. To our knowledge there should be no risk of addiction.
