Tropisetron

NVP Counsellor

Question:
Hi there, Thanks for taking the time to address my query. I am pregnant with my 2nd child and have been suffering from severe NVP. I was hospitalised at 7 weeks and given iv fluids, iv maxolon, and then a dose of iv tropisetron (Navoban). I have since been trying to find out more about the effects of tropisetron in pregnancy and everything I have come across is quite frightening! I'm hoping you can give me some professional advice on this drug. As mentioned, I only had one dose intravenously. With many thanks

Answer:
Tropisetron is an anti-nauseant in the same family of drugs as ondansetron(Zofran). Tropisetron is relatively new and there are no studies on safety in pregnancy. However, Zofran is considered safe to use in pregnancy, so there is no reason to believe that tropisetron is not. Consult your physician for more information. You may also wish to talk to our Motherisk NVP counselor. She can be reached Monday through Friday, 9 a.m. to 5 p.m. ET by dialing 1-800-436-8477.
