Pregnancy, Zofran & Severe Morning Sickness

Using Zofran During Pregnancy

The drug Ondansetron (later branded Zofran) was developed in 1984 to reduce the nausea and vomiting of chemotherapy patients. Zofran has been so effective in reducing nausea and vomiting in chemotherapy patients that doctors have begun prescribing it for severe morning sickness.

Is Zofran Safe for Pregnant Women?

While Zofran appears to be effective in treating nausea and vomiting caused by severe morning sickness, with mostly mild side effects (see below), there is no conclusive research to prove that it doesn't harm the mother or the developing baby. Depending on the severity of the morning sickness, it may be in the best interest of the mother and child to take Zofran. Please learn as much as you can about Zofran, and alternatives before you make a decision.

How Zofran Works

Zofran is an antiemetic which means it is effective in stopping nausea and vomiting. It works by blocking the hormone serotonin which causes vomiting.

Zofran Side Effects

Possible side effects from taking Zofran are (see official Zofran site:

  • headache
  • diarrhea
  • constipation
  • fever
  • malaise/fatigue
  • Lightheadedness
  • Drowsiness

Some women have found this drug to be a miracle which allowed them to have a better pregnancy because they were able to stay hydrated and nourished. Hyperemesis Gravidarum can be devastating for the woman and possible to the baby when the woman is unable to keep anything down and has to be hospitalized for intravenous feeding. Some say taking Zofran as well as Phenergan has been helpful.

Breastfeeding and Zofran

In some of the animal trials they found that Zofram was transferred to the mothers milk which would mean that it should not be taken while nursing.

How to Save Money Buying Discount Zofran

Zofran (aka Ondansetron) is very expensive and many insurance companies will not cover the cost of Zofran. However, there are generic brands of Zofran - just ask your doctor for the generic brand of ondansetron. The high cost of Zofran can make it difficult for women who desperately need the drug. Also it seems that a few doctors are reluctant to prescribe it.
