The Motherisk Nausea and Vomiting of Pregnancy (NVP) ForumMotherisk receives questions from around the world about morning sickness symptoms, effects, treatments and ways to cope. Those questions and answers are posted here for anyone to read, provided the reader acknowledges and accepts the proviso and disclaimer below.
Is Diclectin better then Fenagren? My wife has NVP. She is vomitting at least 2x a day. She is using Fenagren but it does not seem very effective or not as effective as it was. Why is Diclectin not offered in the U.S.?
The efficacy of medication is never the same for everyone. In Canada, Diclectin is the first line of treatment for NVP. In the U.S., Phenergan is one of the most commonly used medications.
Your wife might want to talk to her doctor about her current dose of Phenergan or discuss the use of other available medications, such as combinations of Vitamin B6 and doxylamine succinate.
As for why Diclectin is not offered in the U.S., please use the Motherisk search engine to see various articles posted on this site about Bendectin, such as this update.
