New Study links Antihistamines to Some Birth Risks.
CEDAR RAPIDS, IA (CBS 2/FOX 28)--If you're pregnant, you may want to think twice before taking antihistamines.
A UCLA study released this morning finds some serious side effects from taking the popular medication.
Doctors sometimes prescribe antihistamines as a way to prevent and reduce the nausea and vomiting from severe morning sickness, but even with the new research, some say the connection still requires more study.
"It can relieve the symptoms in some women,” said Dr. Brandon Bourgeous of the cedar rapids ob-gyn specialists.
That's why antihistamines are frequently prescribed for women with severe morning sickness.
The prescription is meant to help them sleep through the symptoms of nausea..
"Women need to know that they may at risk for preterm birth if they take antihistamines for severe nausea pregnancy, said Marlena Fejzo, assistant professor of research in obstetrics and gynecology at UCLA and study lead author.
The six-year study compared pregnancy outcomes of 254 women with severe morning sickness and 308 women who had normal to no morning sickness.
It found that women with the condition and using antihistamines were four times at risk of low birth weight and premature births.
Bourgeous, says the research is interesting but needs more work.
"It looked like it was a pretty small sample size...they were comparing non-medical interventions vs. Medications and there was a whole bunch of different medications that they compared to that,” he said.
In short, the study needs to be bigger.
Still, he does agree with something the researchers also found.
"They found that those medications only worked 20-percent of the time, the antihistamines, and so that supports my experience that antihistamines won't always take care of the patient's symptoms, Bourgeous said.
There are some things that might help, like eating small frequent snacks rather than huge meals. It also helps to avoid greasy and spicy foods
