Nausea can be a very serious issue for some pregnant moms. In many cases it is something that levels off after she enters her second trimester but for some it can be so severe that it threatens the health of both the mother and unborn baby.
The FDA announced on Monday that they have approved Diclegis (doxylamine succinate and pyridoxine hydrochloride) to treat pregnant women experiencing nausea and vomiting.
They say that Diclegis is a delayed-release tablet intended for women who have not adequately responded to conservative management of nausea and vomiting during pregnancy, such as dietary and lifestyle modifications. These modifications include eating several small meals instead of three large meals, eating bland foods that are low in fat and easy to digest and avoiding smells that can trigger nausea.
“Many women experience nausea and vomiting during pregnancy, and sometimes these symptoms are not adequately managed through recommended changes in diet and lifestyle,” said Hylton V. Joffe, M.D., M.M.Sc., director of the Division of Reproductive and Urologic Products in the FDA’s Center for Drug Evaluation and Research. “Diclegis is now the only FDA-approved treatment for nausea and vomiting due to pregnancy, providing a therapeutic option for pregnant women seeking relief from these symptoms.”
In their press release the FDA notes that Diclegis was studied in 261 women experiencing nausea and vomiting due to pregnancy. Study participants in the clinical trial were at least 18 years old and had been pregnant for at least 7 weeks and up to 14 weeks. Women were randomly assigned to receive two weeks of treatment with Diclegis or a placebo. The study results showed that women taking Diclegis experienced greater improvement in nausea and vomiting than those taking placebo. Additionally, observational (epidemiological) studies have shown that the combination of active ingredients in Diclegis does not pose an increased risk of harm to the fetus.
Diclegis is prescribed to be taken daily. Tablets must be taken whole on an empty stomach. The recommended starting dose is two tablets taken at bedtime. If symptoms are not adequately controlled, the dose can be increased to a maximum recommended dose of four tablets daily (one in the morning, one mid-afternoon and two at bedtime).
Drowsiness or sleepiness, which can be severe, is the most common side effect reported by women taking Diclegis. The FDA also says that women should avoid using Diclegis when engaging in activities requiring mental alertness, such as driving or operating heavy machinery, until cleared to do so by their health care provider.
