While researchers are calling this encouraging news to pregnant women, the U.S. Food and Drug Administration (FDA) says more studies must be conducted before the agency will grant approval for the drug to be used in the treatment of morning sickness. After all, the drug carries a black box warning to consumers and health care providers of a serious, debilitating and often irreversible movement disorder called Tardive Dyskinesia. Other problems, it appears, may occur when the medication is taken on a long-term basis, even for pregnant women. 

According to the Canadian research, the length of time on the drug seemed to play a role in the likelihood of birth defects. Children from mothers who took the drug just one week during the first trimester had a 4.9 percent birth defects rate, while babies from mothers who used the drug for more than three months had a 6.1 percent rate of birth defects.

Reglan is approved in the U.S. by the FDA to treat heartburn and a condition known as diabetic gastroparesis. Earlier this year, the FDA issued a black box warning on the medication warning of the increased risk of Tardive Dyskinesia. Individuals who take the medication for longer than 12 weeks are at greatest risk of developing the condition. Elderly women, especially women, are also at greater risk than the general population. Some studies put the risk as high as 20 percent among long-term uses of Reglan.
