The ORIGINAL formula for Bendectin was apparently 10 mg. dicyclomine, 10 mg. doxylamine, and 10 mg. pyridoxine, but the dicyclomine was dropped in 1976. Unisom contains 25 mg. of doxylamine, so the closest you can come to Bendectin is a half tab of unisom (12.5 mg. doxylamine) with 10 mg of pyridoxine. Bendectin had a coating on it which was supposed to allow it to be absorbed slowly overnight so your tummy would still be happy in the morning (the recommendation was to take it at bedtime) but we used to bite it in half before swallowing when urgent relief was needed during the daytime. Doses as low as 50-100mg. per day of pyridoxine (B6) can cause a peripheral neuropathy, but it usually takes more than that and most people don't have a problem with it. There was a study in Ob-Gyn in 1991 that concluded that pyridoxine alone (25 mg. tid X 3 d.) is effective for nausea and vomiting of pregnancy. Bendectin was removed from the market in 1983. I remember it well, because I was right in the middle of my first pregnancy and I quickly bought up the remaining stock in the hospital pharmacy.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
