Question:
Hello, I am about eight weeks pregnant with my second child at thirty seven years old. This is the first time I have had the luxury of getting an anti nausea medicine. I am having severe morning afternoon and evening sickness and I called my doctor. He called me in Ondansetron 4MG ODT TAB. I have been researching this medicine and have read the information that came with it. Frankly, they are scary. I also researched the drug Phenegan and found it was pretty safe. I was wondering is the anti cancer drug as safe as the Phenegan? Or should I ask for the Phenegran. Which one is the safest with the least side effects?

Answer:
Motherisk published a study with almost 200 women taking ondansetron and compared them to a group of women who were not exposed and found no difference in any of the outcomes we looked at. Both of these drugs are considered safe to take in pregnancy and it is between you and your doctor to decide which one you should take.
