Forum > Hyperemesis Gravidarum: Anticipating HG
Medication as soon symptoms arise

NVP Counsellor
Date: 2008-06-18

Question:
I had Hypervarious Gravidarum my last pregnancy and went through several drug reactions before ending up being treated successfully with Zofran (pms-ondansetron). I know that you suggest, for subsequent pregnancies, going on medication as soon as symptoms arise. Is this true for Zofran, or given the lesser amount of information pertaining to this drug (compared for example to Diclectin), should I try to wait until the main organs are formed (ie. 12 weeks gestation). Thanks.

Answer:
Yes it is true,for whatever medication you are taking including Zofran. When we conducted our study of premptive treatment, many of the women in the study were taking Zofran. You should not wait until you are 12 weeks pregnant, especially if you suffered from HG in your previous pregnancy.
