Update about Vitamin B6 & Unisom

Unisom is the brand name of doxylamine, a drug used for the short-term treatment of insomnia. It is manufactured by Chattem, Inc. and is available in several local pharmacies without a prescription. It can also be used to relieve allergy symptoms by blocking the action of chemical histamine. Vitamin B-6 is a water-soluble vitamin that plays an important role in fighting infections and maintaining nerve function. It can be obtained from foods such as avocados, bananas, legumes, nuts, meat, and synthetic supplements. Unisom in combination with vitamin B-6 can help control nausea and vomiting.

About Nausea and Vomiting
Nausea is the urge to vomit, while vomiting forces the stomach contents up and out of the mouth; in this way the body responds to invaders and irritants. Certain infections, medications, dizziness, morning sickness, chemotherapy, and brain tumors often lead to nausea and vomiting. In addition to avoiding triggers, certain medications can also help prevent the conditions.

Unisom and Vitamin B-6 for Nausea and Vomiting
Taking vitamin B-6 supplements along with doxylamine is a safe and effective way to reduce nausea and vomiting associated with morning sickness and should be considered the first line of treatment, according to guidelines issued by the American Congress of Obstetricians and Gynecologists. An article published in the October 2010 issue of the New England Journal of Medicine states that this combination can reduce nausea and vomiting by almost 70 percent.

Side effects
Doxylamine and vitamin B-6 used to be sold together as a combination. However, it was discontinued because some previous studies indicated that this combination increased the risk of birth defects. These concerns have now been found to be unfounded, says Mindy A. Smith,who is the author of “Twenty Common Problems in Women’s Health Care” . Doxylamine, or Unisom, is also associated with side effects such as dry mouth, drowsiness, headache, and nervousness, while large doses of vitamin B-6 can also cause numbness and sensory changes.

Although both vitamin B-6 and Unisom are available without a prescription, it is best to talk to a doctor to see if they are right for you. Your doctor can also help determine an appropriate dose. Tell your doctor about any other medications or pre-existing conditions to avoid possible interactions and complications.
