Zofran

PRACTICE AREA

Zofran

According to the National Institutes of Health and other published medical research, nausea and vomiting during pregnancy occurs in 80-85% of pregnant women. Several medications can be used to alleviate what is commonly referred to as morning sickness, but there is insufficient data on how these drugs correlate with birth defects. Some anti-nausea medications, which were previously believed to be safe for pregnant women, now come with black box warning labels, the strongest warning label available before a drug must be pulled from the market.

What is Zofran?

Zofran (Ondansetron) was developed to aid cancer patients with nausea after surgery, chemotherapy, and radiation. Zofran is typically administered via an orally swallowed tablet, at a rate of once or twice per day. The drug helps block chemicals in the body that cause nausea, and is commonly prescribed off-label to women facing extreme bouts of nausea and vomiting during pregnancy. Since chemotherapy patients and pregnant women who are already nauseous and vomiting will potentially throw up a tablet, the medication is also available in dissolvable wafers and injections.

Zofran Use During Pregnancy

The U.S. Food and Drug Administration (FDA) has not restricted the sale of Zofran, and doctors are free to prescribe it as they choose, regardless of its intended purpose. Although doctors can legally prescribe Zofran to pregnant women, patients have the right to know the potential risks of their medication, and pharmaceutical manufacturers and distributors must advise pregnant women of the hazards posed to the mother and unborn child.

The majority of pregnancy-induced nausea and vomiting is experienced during the first trimester of pregnancy, when many of the fetus’s primary bodily systems and functions are still developing, making the fetus particularly susceptible to serious side effects from in utero exposure to toxins.

There is an increasing trend to prescribe Zofran for nausea and vomiting in pregnant women, even though its safety for use during pregnancy remains unknown. This is largely because there is no FDA-approved drug for morning sickness. Zofran is not labeled for use to combat nausea and vomiting in pregnancy in either the United States or Canada.

Studies, including one published in China, have found the drug teratogenic (able to cause congenital birth defects) because it is readily able to pass through the placenta in early pregnancy in a concentration high enough to cause abnormal fetal development. The Slone Epidemiology Center and the Centers for Disease Control and Prevention (CDC) found women exposed to the 5HT3-receptor antagonist Zofran during the first trimester of pregnancy had a 2.37 times increased risk of having a child born with a cleft palate birth defect.

Although the medication has proven effective against nausea, the FDA has issued an updated warning that it is continuing to evaluate whether taking Zofran while pregnant may cause serious birth defects or complications for the mother. This medicine is still being prescribed to many women unaware of potential side effects.

What Birth Defects Can Zofran Cause?

Infants born to mothers who took Zofran during pregnancy may be born with malformations of the mouth, including a cleft lip or cleft palate. A cleft palate refers to a split in the roof of the mouth, while a cleft lip includes a gather or split in the mouth area. These disfigurations of the face can range from visible facial marks to massive developmental shortcomings, which can cause difficulty eating and/or breathing. Although modern surgeries can sometimes correct these birth defects, a child may face a lifetime of scarring or injuries so severe they cannot be fully corrected. According to a study conducted by the National Center for Biotechnology Information, taking Zofran during pregnancy can increase a baby’s risk of being born with a cleft palate twofold.

Zofran birth complications also include defects in the development of the infant’s heart. A baby may face life-threatening complications during the pregnancy, birth, or for the rest of his or her life as a result of heart defects, including congenital heart defects that threaten their lives.

At least one study showed women who took Zofran at any time during pregnancy had a 2.0 times increased risk of their baby being born with an APGAR score of less than six as long as five minutes after birth. This commonly used measurement of a newborn’s health determines the condition of the infant on a scale of one to ten, with a score of six or lower after five minutes indicating the baby may need medical assistance. The same study found an increased risk of a major birth defect, preterm birth, and shorter birth length with Zofran ingestion during pregnancy.

An article in Reproductive Toxicology found the risk of a cardiovascular defect, most notably a cardiac septum defect, was increased and statistically significant. This indicates an increased risk that mothers who take Zofran during pregnancy will give birth to a baby with a “hole in the heart,” also known as an atrial septal defect or a ventral septal defect. The article cites a Denmark study showing a 2.0 times increased risk of congenital heart malformation after first trimester in utero exposure to Zofran.
